If MICROPY_HW_RTC_USE_BYPASS is enabled the RTC startup goes as follows:
- RTC is started with LSE in bypass mode to begin with
- if that fails to start (after a given timeout) then LSE is reconfigured
in non-bypass
- if that fails to start then RTC is switched to LSI
The qstr window size is not log-2 encoded, it's just the actual number (but
in mpy-tool.py this didn't lead to an error because the size is just used
to truncate the window so it doesn't grow arbitrarily large in memory).
Addresses issue #4635.
When running Linux on WSL, Popen.kill() can raise a ProcessLookupError if
the process does not exist anymore, which can happen here since the
previous statement already tries to close the process by sending Ctrl-D to
the running repl. This doesn't seem to be a problem on other OSes, so just
swallow the exception silently since it indicates the process has been
closed already, which after all is what we want.
Since commit da938a83b5 the tcp_arg() that is
set for the new connection is the new connection itself, and the parent
listening socket is found in the pcb->connected entry.
Use uos.dupterm for REPL configuration of the main USB_VCP(0) stream on
dupterm slot 1, if USB is enabled. This means dupterm can also be used to
disable the boot REPL port if desired, via uos.dupterm(None, 1).
For efficiency this adds a simple hook to the global uos.dupterm code to
work with streams that are known to be native streams.
These macros are unused, and they can conflict with other entities by the
same name. If needed they can be provided as static inline functions, or
just functions.
Fixes issue #4559.
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.
For gpio_hold_en() to work properly (not draw additional current) pull
up/down must be disabled when hold is enabled. This patch makes sure this
is the case by reworking the pull constants to be a bit mask.
Adding section about on how to disable use of the linker flag
-flto, by setting the LTO=0 argument to Make. Also, added a
note on recommended toolchains to use that works well with
LTO enabled.
Removing linker script for nrf52840 s140 v6.0.0 as pca10056
target board now points to the new v6.1.1. Also, removing the
entry from the download_ble_stack.sh script.
