Damien George ea033bf25a stm32/powerctrl: Add hooks for a board to perform actions on sleep/wake. 2019-07-03 01:27:33 +10:00
Damien George caabdd99c0 stm32/qspi: Handle bus acquisition.
When going out of memory-mapped mode to do a control transfer to the QSPI
flash, the MPU settings must be changed to forbid access to the memory
mapped region.  And any ongoing transfer (eg memory mapped continuous read)
must be aborted.

Damien George 2034c0a2e3 stm32/qspi: Force a reset of the QSPI peripheral when initialising it.
To ensure it is in a known state on start up.

Damien George 8da39fd182 stm32/qspi: Use MPU to allow access to valid memory-mapped QSPI region.
The Cortex-M7 CPU will do speculative loads from any memory location that
is not explicitly forbidden.  This includes the QSPI memory-mapped region
starting at 0x90000000 and with size 256MiB.  Speculative loads to this
QSPI region may 1) interfere with the QSPI peripheral registers (eg the
address register) if the QSPI is not in memory-mapped mode; 2) attempt to
access data outside the configured size of the QSPI flash when it is in
memory-mapped mode.  Both of these scenarios will lead to issues with the
QSPI peripheral (eg Cortex bus lock up in scenario 2).

To prevent such speculative loads from interfering with the peripheral the
MPU is configured in this commit to restrict access to the QSPI mapped
region: when not memory mapped the entire region is forbidden; when memory
mapped only accesses to the valid flash size are permitted.

Damien George 999733b1fb minimal: Use soft float for CROSS=1 Cortex-M4 target.
When compiled with hard float the system should enable FP access when it
starts or else FP instructions lead to a fault.  But this minimal port does
not enable (or use) FP and so, to keep it minimal, switch to use soft
floating point.  (This became an issue due to the recent commit
34c04d2319 which saves/restores FP registers
in the NLR state.)

Chris Mason 3786592097 stm32/boards: Optimise flash and RAM allocation for L4 boards.
Optimisations are:
- Remove FLASH_ISR section since devices with a small flash sector erase
  size don't need special FLASH_ISR handling.  This reduces flash image by
  approx 1.5k.
- Make SRAM2 contiguous with SRAM1 where possible.
- Simplify configuration of 2k RAM buffer used for flash filesystem.

RAM changes with this commit:
- L432: stack   6k -> 10k,  bss + heap   42k ->  52k
- L476: stack  16k -> 30k,  bss + heap   80k ->  96k
- L496: stack 206k -> 16k,  bss + heap  112k -> 302k

Damien George d21d578644 stm32/usb: Fix regression with auto USB PID value giving PID=0xffff.
Commit 9e68eec8ea introduced a regression

Damien George 89ebb3325b stm32/boards/pllvalues.py: Support HSx_VALUE defined without uint32_t. 2019-06-25 14:18:24 +10:00
Damien George 04c7cdb668 stm32: Enter bootloader via a system reset.
Entering a bootloader (ST system bootloader, or custom mboot) from software
by directly branching to it is not reliable, and the reliability of it
working can depend on the peripherals that were enabled by the application
code.  It's also not possible to branch to a bootloader if the WDT is
enabled (unless the bootloader has specific provisions to feed the WDT).

This patch changes the way a bootloader is entered from software by first
doing a complete system reset, then branching to the desired bootloader
early on in the start-up process.  The top two words of RAM (of the stack)
are reserved to store flags indicating that the bootloader should be
entered after a reset.

Damien George b80bccccff esp32/modnetwork: Still try to reconnect to WLAN even with AUTH_FAIL.
WIFI_REASON_AUTH_FAIL does not necessarily mean the password is wrong, and
a wrong password may not lead to a WIFI_REASON_AUTH_FAIL error code.  So to
improve reliability connecting to a WLAN always reconnect regardless of the
error.

Chris Mason 14cf91f704 stm32: In link script, define start of stack separately from heap end.
Previously the end of the heap was the start (lowest address) of the stack.
With the changes in this commit these addresses are now independent,
allowing a board to place the heap and stack in separate locations.

Damien George 8b18cfedee stm32/usbd_msc: Allow to compile when USB enabled and SD card disabled. 2019-06-11 21:01:14 +10:00
Damien George 53200247b7 stm32/usb: Add "msc" kw-arg to pyb.usb_mode to select MSC logical units.
With this the user can select multiple logical units to expose over USB MSC
at once, eg: pyb.usb_mode('VCP+MSC', msc=(pyb.Flash(), pyb.SDCard())).  The
default behaviour is the original behaviour of just one unit at a time.

Damien George 9e68eec8ea stm32/usb: Use ARG_xxx enums to access kw args in pyb_usb_mode. 2019-06-11 15:50:21 +10:00
Damien George 38bcc99a58 stm32/usbd_msc: Provide Mode Sense response data in MSC interface.
Eventually these responses could be filled in by a function to make their
contents dynamic, depending on the attached logical units.  But for now
they are fixed, and this patch fixes the MODE SENSE(6) responses so it is
the correct length with the correct header.
2019-06-11 15:43:59 +10:00
Damien George 829aa58c5c stm32/usbd_msc: Provide custom irquiry processing by MSC interface.
So the MSC interface can customise the inquiry response based on the
attached logical units.
2019-06-11 15:43:58 +10:00
Damien George 518aa571ab stm32/usbd_msc: Rework USBD MSC code to support multiple logical units.
SCSI can support multiple logical units over the one interface (in this
case over USBD MSC) and here the MSC code is reworked to support this
feature.  At this point only one LU is used and the behaviour is mostly
unchanged from before, except the INQUIRY result is different (it will
report "Flash" for both flash and SD card).

Damien George fd839221fd stm32/boards/PYBD_SFx: Enable ussl module using mbedTLS. 2019-06-05 15:38:01 +10:00
Damien George fed4c23590 stm32: Integrate optional mbedTLS component for ussl module.
To use it a board should define MICROPY_PY_USSL=1 and MICROPY_SSL_MBEDTLS=1
at the Makefile level.  With the provided configuration it adds about 64k
to the build.
2019-06-05 15:37:31 +10:00
Damien George 9d72f07b6d unix/mpconfigport.mk: Update comment about TLS implementations.
As long as the submodule is checked out, mbedTLS is now fully integrated

2019-06-05 15:28:30 +10:00
Damien George ce8262a164 stm32/modnetwork: Replace generic netif NIC polling with specific code.
It doesn't work to tie the polling of an underlying NIC driver (eg to check
the NIC for pending Ethernet frames) with its associated lwIP netif.  This
is because most NICs are implemented with IRQs and don't need polling,
because there can be multiple lwIP netif's per NIC driver, and because it
restricts the use of the netif->state variable.  Instead the NIC should
have its own specific way of processing incoming Ethernet frame.

This patch removes this generic NIC polling feature, and for the only
driver that uses it (Wiznet5k) replaces it with an explicit call to the
poll function (which could eventually be improved by using a proper
external interrupt).

Nicko van Someren 8e3af7d4c8 esp32: Add machine.SDCard class using built-in HW SD/MMC controller.
This adds support for SD cards using the ESP32's built-in hardware SD/MMC
host controller, over either the SDIO bus or SPI.  The class is available
as machine.SDCard and using it can be as simple as:

    uos.mount(machine.SDCard(), '/sd')

",PA0".  If the board-pin name starts with a hyphen then it's available as
a C definition but not in the firmware, eg "-X1,PA0".
2019-05-31 21:41:30 +10:00
Damien George 3fc7c8e35c stm32/usb: Include py/mpconfig.h instead of mpconfigboard.h.

Martin Dybdal de76f73d34 esp32/machine_timer: Reuse Timer handles, deallocate only on soft-reset.
The patch solves the problem where multiple Timer objects (e.g. multiple
Timer(0) instances) could initialise multiple handles to the same internal
timer.  The list of timers is now maintained not for "active" timers (where
init is called), but for all timers created.  The timers are only removed
from the list of timers on soft-reset (machine_timer_deinit_all).

Fixes #4078.

Damien George 0c29502ad9 stm32/usb: Refactor CDC VCP code to enable N CDC interfaces.
The board config option MICROPY_HW_USB_ENABLE_CDC2 is now changed to
MICROPY_HW_USB_CDC_NUM, and the latter should be defined to the maximum
number of CDC interfaces to support (defaults to 1).

Paul Sokolovsky c4a6d9c631 zephyr: Switch back to enabling I2C in board-specific configs.
I2C can't be enabled in prj_base.conf because it's a board-specific
feature.  For example, if a board doesn't have I2C but CONFIG_I2C=y then
the build will fail (on Zephyr build system side).  The patch here gets the

Damien George e1e3704aa1 stm32/modmachine: Create dedicated asm function to branch to bootloader.
Recent gcc versions (at least 9.1) give a warning about using "sp" in the

The old code also didn't validate the return value of setsockopt, missing
the bug completely.

Damien George b8c74014e4 stm32/usbd_cdc_interface: Don't retransmit chars if USB is reconnected.
Before this change, if the USB was reconnected it was possible that some
characters in the TX buffer were retransmitted because tx_buf_ptr_out and
tx_buf_ptr_out_shadow were reset while tx_buf_ptr_in wasn't.  That
behaviour is fixed here by retaining the TX buffer state across reconnects.

Fixes issue #4761.

Damien George 97753a1bbc stm32: Move factory reset files and code to separate source file.
The new function factory_reset_make_files() populates the given filesystem
with the default factory files.  It is defined with weak linkage so it can
be overridden by a board.

This commit also brings some minor user-facing changes:

- boot.py is now no longer created unconditionally if it doesn't exist, it
  is now only created when the filesystem is formatted and the other files
  are populated (so, before, if the user deleted boot.py it would be
  recreated at next boot; now it won't be).

- pybcdc.inf and README.txt are only created if the board has USB, because
  they only really make sense if the filesystem is exposed via USB.

Damien George 34942d0a72 stm32/machine_uart: Change default UART timeout to 0, for non blocking.
It's more common to need non-blocking behaviour when reading from a UART,
rather than having a large timeout like 1000ms (the original behaviour).
With a large timeout it's 1) likely that the function will read forever if
characters keep trickling it; or 2) the function will unnecessarily wait
when characters come sporadically, eg at a REPL prompt.

Also, the LED module has been updated to support individual base level
configuration of each LED. If set, this will be used instead of the
common configuration, MICROPY_HW_LED_PULLUP. The new configuration,
MICROPY_HW_LEDX_LEVEL, where X is the LED number can be used to set
the base level of the specific LED.

Chris Mason 2a791170ce stm32/boards: Add NUCLEO_F413ZH board configuration.
The alternate function pin allocations are different to other NUCLEO-144
boards.  This is because the STM32F413 has a very high peripheral count:
10x UART, 5x SPI, 3x I2C, 3x CAN.  The pinout was chosen to expose all
these devices on separate pins except CAN3 which shares a pin with UART1
and SPI1 which shares pins with DAC.

stijn 34a7d7ebeb unix/gcollect: Make sure stack/regs get captured properly for GC.
When building with link time optimization enabled it is possible both
gc_collect() and gc_collect_regs_and_stack() get inlined into gc_alloc()
which can result in the regs variable being pushed on the stack earlier
than some of the registers. Depending on the calling convention, those
registers might however contain pointers to blocks which have just been
allocated in the caller of gc_alloc(). Then those pointers end up higher on
the stack than regs, aren't marked by gc_collect_root() and hence get
sweeped, even though they're still in use.

As reported in #4652 this happened for in 32-bit msvc release builds:
mp_lexer_new() does two consecutive allocations and the latter triggered a
gc_collect() which would sweep the memory of the first allocation again.

reset the device if the interval expires (instead of just printing an error
message).

Damien George 8031b7a25c stm32/powerctrl: Deselect PLLSAI as 48MHz src before turning off PLLSAI.
On the STM32F722 (at least, but STM32F767 is not affected) the CK48MSEL bit
must be deselected before PLLSAION is turned off, or else the 48MHz
peripherals (RNG, SDMMC, USB) may get stuck without a clock source.

In such "lock up" cases it seems that these peripherals are still being
clocked from the PLLSAI even though the CK48MSEL bit is turned off.  A hard
reset does not get them out of this stuck state.  Enabling the PLLSAI and
then disabling it does get them out.  A test case to see this is:

    import machine, pyb
    for i in range(100):
        machine.freq(122_000000)
        machine.freq(120_000000)
        print(i, [pyb.rng() for _ in range(4)])

On occasion the RNG will just return 0's, but will get fixed again on the
next loop (when PLLSAI is enabled by the change to a SYSCLK of 122MHz).

Fixes issue #4696.

Damien George 0646e607b5 ports: Convert to use pyexec_file_if_exists() to execute boot/main.py.
The stm32 and nrf ports already had the behaviour that they would first
check if the script exists before executing it, and this patch makes all
other ports work the same way.  This helps when developing apps because
it's hard to tell (when unconditionally trying to execute the scripts) if
the resulting OSError at boot up comes from missing boot.py or main.py, or
from some other error.  And it's not really an error if these scripts don't
exist.

Damien George aa7b32c811 stm32/dac: Rework DAC driver to use direct register access.
This patch makes the DAC driver simpler and removes the need for the ST
HAL.  As part of it, new helper functions are added to the DMA driver,
which also use direct register access instead of the ST HAL.

Main changes to the DAC interface are:

- The DAC uPy object is no longer allocated dynamically on the heap,
  rather it's statically allocated and the same object is retrieved for
  subsequent uses of pyb.DAC(<id>).  This allows to access the DAC objects
  without resetting the DAC peripheral.  It also means that the DAC is only
  reset if explicitly passed initialisation parameters, like "bits" or
  "buffering".

- The DAC.noise() and DAC.triangle() methods now output a signal which is
  full scale (previously it was a fraction of the full output voltage).

- The DAC.write_timed() method is fixed so that it continues in the
  background when another peripheral (eg SPI) uses the DMA (previously the
  DAC would stop if another peripheral finished with the DMA and shut the
  DMA peripheral off completely).

Based on the above, the following backwards incompatibilities are
introduced:

- pyb.DAC(id) will now only reset the DAC the first time it is called,
  whereas previously each call to create a DAC object would reset the DAC.
  To get the old behaviour pass the bits parameter like: pyb.DAC(id, bits).

- DAC.noise() and DAC.triangle() are now full scale.  To get previous
  behaviour (to change the amplitude and offset) write to the DAC_CR (MAMP
  bits) and DAC_DHR12Rx registers manually.

Maureen Helm 2befcb8a9d zephyr/i2c: Add support for hardware i2c.
Adds support for hardware i2c to the zephyr port. Similar to other ports
such as stm32 and nrf, we only implement the i2c protocol functions
(readfrom and writeto) and defer memory operations (readfrom_mem,
readfrom_mem_into, and writeto_mem) to the software i2c implementation.
This may need to change in the future because zephyr is considering
deprecating its i2c_transfer function in favor of i2c_write_read; in this
case we would probably want to implement the memory operations directly
using i2c_write_read.

Tested with the accelerometer on frdm_k64f and bbc_microbit boards.

Andrew Leech 0c60cb1fc4 stm32/qspi: Set pin speed to very-high and allow to config some options.
The default speed of the QSPI interface is 72Mhz whereas the standard AF
pin speed (high) is only rated to 50Mhz, so increase speed to very-high.
2019-03-08 23:17:50 +11:00
Andrew Leech 89ff506513 py: Update and rework build system for including external C modules.

Francisco J. Manno f938e70c69 stm32: Add compile-time option to use HSI as clock source.
To use HSI instead of HSE define MICROPY_HW_CLK_USE_HSI as 1 in the board
configuration file.  The default is to use HSE.

HSI has been made the default for the NUCLEO_F401RE board to serve as an
example, and because early revisions of this board need a hardware
modification to get HSE working.

Damien George 84479569de stm32/boards/STM32F769DISC: Use external QSPI flash to store some code.
This demonstrates how to use external QSPI flash in XIP (execute in place)
mode.  The default configuration has all extmod/ code placed into external
QSPI flash, but other code can easily be put there by modifying the custom
f769_qspi.ld script.
2019-03-04 22:40:15 +11:00
Damien George c8bbf2c170 stm32/Makefile: Allow a board to specify its linker sections for FW.
A board can now use the make variables TEXT0_SECTIONS and TEXT1_SECTIONS to
specify the linker sections that should go in its firmware.  Defaults are
provided which give the existing behaviour.
2019-03-04 22:26:55 +11:00
Damien George f8f2724297 stm32/qspi: Enable sample shift and disable timeout counter.
This makes the QSPI more robust, in particular the timeout counter should
not be used with memory mapped mode (see F7 errata).
2019-03-01 16:15:14 +11:00
Damien George 47e551ba59 cc3200/mpconfigport.h: Disable compiler optimisation of OrderedDict.

Damien George 8ce22662fe esp8266/modmachine: Call ets_event_poll after waiti in machine.idle.
Because "waiti 0" may have waited for a while (eg 500ms) and the internal
WDT may need to be fed immediately.

Fixes issue #4459.

Petr Kracík 21f9329d5d esp32/modnetwork: Fix wifi.isconnected to return False after disconnect.
esp_wifi_connect will return ESP_OK for the normal path of execution which
just means the reconnect is started, not that it is actually reconnected.
In such a case wifi.isconnected() should return False until the
reconnection is complete.  After reconnect a GOT_IP event is called and it
will change wifi_sta_connected back to True.
2019-02-26 00:49:40 +11:00
Damien George 55ff562c70 unix/modffi: Eliminate unused-argument warning when debugging disabled. 2019-02-25 14:53:17 +11:00
Petr Kracík 5801a003f0 esp32/network_lan: Make power arg to constructor optional.
A value of None for this argument is already supported, so the argument can
be made optional.

Glenn Ruben Bakke ca2bb66127 nrf/bluetooth: Resolve compilation warning in ble_drv.c.
This patch makes sure that the char_data.props is first
assigned a value before other flags are OR'd in.
Resolves compilation warning on possible unitialized variable.
2019-02-20 07:25:51 +01:00
Glenn Ruben Bakke 0c6f5bc529 nrf/bluetooth: Improve advertisment behavior for nrf52 targets.
This patch makes sure that advertisment data is located in
persistent static RAM memory throughout the advertisment.

Also, setting m_adv_handle to predifined
BLE_GAP_ADV_SET_HANDLE_NOT_SET value to indicate first time
usage of the handle. Upon first advertisment configuration
this will be populated with a handle value returned by the
stack (s132/s140).
2019-02-20 07:25:51 +01:00
Glenn Ruben Bakke ee3a01f25c nrf/readme: Update link to nrfjprog download.
After new layout of nordicsemi.com the direct links to
command line tools (nrfjprog) has changed to become dynamic.
This patch removes the old direct links to each specific OS
variant and is replaced with one single link to the download
landing page instead.
2019-02-20 07:13:36 +01:00
Andrew Leech 8ed4a28dae stm32/sdram: Increase GPIO speed for SDRAM interface to "very high".
Currently all usages of mp_hal_pin_config_alt_static() set the pin speed to
"high" (50Mhz).  The SDRAM interface typically runs much faster than this
so should be set to the maximum pin speed.

This commit adds mp_hal_pin_config_alt_static_speed() which allows setting
the pin speed along with the other alternate function details.

Dave Hylands 92fec603d0 stm32/make-stmconst.py: Improve regex to parse more constants.
A few RTC constants weren't being parsed properly due to whitespace
differences, and this patch makes certain whitespace optional.  Changes
made:

- allow for no space between /*!< and EXTI, eg for:
  __IO uint32_t IMR; /*!<EXTI Interrupt mask register, Address offset: 0x00 */

- allow for no space between semicolon and start of comment, eg for:
  __IO uint32_t ALRMASSR;/*!< RTC alarm A sub second register, Address offset: 0x44 */

Damien George c65e5c88b8 stm32/boards/stm32f429.ld: Increase uPy heap size by 64k for F429 MCU.
The F429 has 256k total RAM, with 64k already set aside for flash write
cache, so the uPy heap can be increased this much.

Yonatan Goldschmidt 66f0afc91d unix/modmachine: Handle repeated /dev/mem open errors.
If opening of /dev/mem has failed an `OSError` is appropriately raised, but
the next time `mem8/16/32` is accessed the invalid file descriptor is used
and the program gets a SIGSEGV.

Mike Causer 812969d615 all: Change PYB message prefix to MPY.
Replaces "PYB: soft reboot" with "MPY: soft reboot", etc.

Having a consistent prefix across ports reduces the difference between
ports, which is a general goal.  And this change won't break pyboard.py
because that tool only looks for "soft reboot".
