Based on my experience, there's rather non-zero chance to have an image be
flashed incorrectly. As --verify option is now works well in teh latest
esptool.py, enable it by default.
By design, at wake up from deepsleep, the RTC timer will be reset, but
the data stored in RTC memory will not [1]. Therefore, we have to adjust
delta in RTC memory before going into deepsleep to get almost correct
time after waking up.

Instead of calling strlen(), which won't work if there're 32 chars in
returned ESSID. struct bss_info::ssid_len is not documented in SDK API
Guide, but is present in SDK headers since 1.4.0. Just in case, previous
code is left commented.
ESP-SDK system_get_rtc_time() returns uint32 and therefore overflow
about every 7:45h. Let's write the last state of system_get_rtc_time()
in RTC mem and use it to check for overflow. This commit require running
pyb_rtc_get_us_since_2000() at least once within 7 hours to avoid
overflow.
This implementation makes use of vfs.stat() and therefore has the same
properties. Known issues for all ports: uos.stat(".") on the top level
returns the error code 22, EINVAL. The same happens with
uos.stat("dirname/") where dirname IS the name of a directory.
Ctrl-C will raise a KeyboardInterrupt and stop the scan (although it will
continue to run in the background, it won't report anything). If
interrupted, and another scan() is started before the old one completes
in the background, then the second scan will fail with an OSError.
ets_loop_iter processes pending tasks, and tasks are considered lower
priority than interrupts, so tasks shouldn't be processed if interrupts
are disabled.
Make dupterm subsystem close a term stream object when EOF or error occurs.
There's no other party than dupterm itself in a better position to do this,
and this is required to properly reclaim stream resources, especially if
multiple dupterm sessions may be established (e.g. as networking
connections).
Adding a very first start section to get people going after flashing.
I tried to condense it to a minimum to avoid as much as possible
redundancy and bloating.
That one was missing in the module, even if it was available in the
vfs object. The change consist of adding the name and preparing the
call to the underlying vfs module, similar to what was already
implemented e.g. for remove.
Rename is useful by itself, or for instance for a safe file replace,
consisting of the sequence:
write to a temp file
delete the original file
rename the temp file to the original file's name
These symbols are still defined in terms of the system Exxx symbols, and
can be switched to internal numeric definitions at a later stage.
Note that extmod/modlwip still uses many system Exxx symbols.
This is kind of compensation for 4K FatFs buffer size which is eaten away
from it on FS mount. This should still leave enough of networking ("OS")
heap.
It interferes with running testsuite. master branch should be optimized for
development, so any features which interfere with that, would need to be
disabled by default.
