|

#
|
||||
# Flash libraries for CC2652: read, write, verify...
|
||||
#
|
||||
# The serial protocol requires the CC2652 to boot in BSL (bootloader) mode.
|
||||
# On Sonoff Zigbee Bridge Pro, it requires to reset the MCU with DIO_8 low.
|
||||
#
|
||||
# When starting the flasher, normal zigbee operations are aborterd. Restarting
|
||||
# normal zigbee functions requires a Tasmota restart.
|
||||
#
|
||||
# Required condiguration:
|
||||
# - Zigbee Rx: must be configured as `Zigbee Rx` or `TCP Rx`
|
||||
# - Zigbee Tx: must be configured as `Zigbee Tx` or `TCP Tx`
|
||||
# - Zigbee Reset: must be configured as `Zigbee Rst - 1``
|
||||
# - Zigbee BSL mode (low): must be configured as `Zigbee Rts - 2`
|
||||
# For Sonoff Zibeee Bridge Pro: Rx=23 Tx=19 Rst-1=15 Rst-2=22
|
||||
#
|
||||
# How to use:
|
||||
# - `import cc2652_flasher as cc`
|
||||
# aborts all zigbee operations and configures the serial port
|
||||
# Output: `FLH: cc2652_flasher rx=23 tx=19 rst=15 bsl=22`
|
||||
#
|
||||
# - `cc.start()` to start the flasher`
|
||||
# restarts the CC2652 in BSL mode, and establishes connection
|
||||
# Use `cc.start(true)` to enable debug verbose mode
|
||||
#
|
||||
# - `cc.ping()` sends a ping command and waits for ACK (does nothing)
|
||||
#
|
||||
# - `cc.cmd_get_chip_id()` returns the chip ID
|
||||
#
|
||||
# - `cc.flash_read(addr, len)` reads `len` bytes from address `addr``
|
||||
# len must be a multiple of 4 and less or equal than 128 bytes
|
||||
# Returns a bytes() object
|
||||
#
|
||||
# - `cc.flash_crc32(addr, len)` returns the CRC32 of a flash region
|
||||
#
|
||||
# - `cc.flash_write(addr, data)` writes bytes to the flash
|
||||
# `data` is a bytes() buffer, its len must be a multiple of 4 and less or equal than 128
|
||||
# This call does not erase the flash, so it must have been erased before.
|
||||
# The bootloader checks that the bytes were correctly written, i.e. that
|
||||
# the appropriate bits were changed from `1` to `0`.
|
||||
# Chaning bits from `0` to `1` requires a flash erase.
|
||||
#
|
||||
# - `cc.flash_erase()` erase the entire flash.
|
||||
# Use with caution. After the flash is erased, there is no valid application
|
||||
# in flash so the MCU always starts in BSL bootloader mode until a valid
|
||||
# app is flashed.
|
||||
#
|
||||
# - `cc.flash_dump_to_file(filename, addr, len)` dumps the CC2652 flash into a file
|
||||
# `filename` is the output file in binary format, make sure there are 360KB free in filesystem.
|
||||
# Dumping the complete file is done as follows (it takes 3 minutes during which Tasmota is unresponsive):
|
||||
# `cc.dump_to_file("cc2652_dump.bin", 0x00000, 0x58000)`
