When UART is used for REPL and the MCU frequency is changed, the UART
has to be re-initialised. Besides that the UART may have to be recreated
after a frequency change, but with USB REPL this is not a problem.
Thanks to @HermannSW for spotting and providing the change.
Using the standard machine.freq().
The safe ranges tested were 10 and 12-270MHz, at which USB REPL still
worked. Requested settings can be checked with the script:
pico-sdk/src/rp2_common/hardware_clocks/scripts/vcocalc.py. At frequencies
like 300MHz the script still signaled OK, but USB did not work any more.
sm.get(buf) was waiting for one item more than the length of the supplied
buffer. Even if this item was not stored, sm_get would block trying to get
an item from the RX fifo.
As part of the fix, the edge case for a zero length buffer was moved up to
the section where the function arguments are handled. In case of a zero
length buffer, sm.get() now returns immediately that buffer.
The bitmasks supplied for initialization of out/set/sideset were only 8 bit
instead of 32. This resulted in an error, that not more than 8 consecutive
pins would get initialized.
Fixes issue #6933.
From a version numbering point of view this is a downgrade (2.17.0 ->
2.16.x). However the latest commit for version 2.17.0 is from March 2019
and no further minor release happened after 2.17.0. This version is EOL.
2.16.x though is still actively maintained as a long term release, hence
security and stability fixes are still being backported, including
compatibility with upcoming compiler releases.
This allows the user to enable wake-up sources using the EWUP bits, on F7
MCUs.
Disabling the wake-up sources while clearing the wake-up flags follows the
reference manual and ST examples.
state.reset_mode is updated by `MICROPY_BOARD_BEFORE_SOFT_RESET_LOOP` but
not passed to `init_flash_fs`, and so factory reset is not executed on
boards that do not have a bootloader. This bug was introduced by
4c3976bbcaFixes#6903.
A corrupt filesystem may lead to a request for a block which is out of
range of the block device limits. Return an error instead of passing the
request down to the lower layer.
Two of the defaults have also changed in this commit:
- MICROPY_HW_RFCORE_BLE_LSE_SOURCE changed from 1 to 0, which configures
the LsSource to be LSE (needed due to errata 2.2.1).
- MICROPY_HW_RFCORE_BLE_VITERBI_MODE changed from 0 to 1, which enables
Viterbi mode, following all the ST examples.

Instead of raising a ZeroDivisionError, this tool now just skips any
elements in the DFU file that have zero size.

These ports already have uzlib enabled so this additional ubinascii.crc32
function only costs about 90 bytes of flash.

This allows a port to specify a custom qstrdefsport.h file, the same as the
QSTR_DEFS variable in a Makefile.

Add LPUART1 as a standard UART. No low power features are supported, yet.
LPUART1 is enabled as the next available UART after the standard U(S)ARTs:
STM32WB: LPUART1 = UART(2)
STM32L0: LPUART1 = UART(6)
STM32L4: LPUART1 = UART(6)
STM32H7: LPUART1 = UART(9)
On all ports: LPUART1 = machine.UART('LP1')
LPUART1 is enabled by defining MICROPY_HW_LPUART1_TX and
MICROPY_HW_LPUART1_RX in mpconfigboard.h.

Previously, the MICROPY_PY_BLUETOOTH_ENABLE_CENTRAL_MODE macro
controlled enabling both the central mode and the GATT client
functionality (because usually the two go together).
This commits adds a new MICROPY_PY_BLUETOOTH_ENABLE_GATT_CLIENT
macro that separately enables the GATT client functionality.
This defaults to MICROPY_PY_BLUETOOTH_ENABLE_CENTRAL_MODE.
This also fixes a bug in the NimBLE bindings where a notification
or indication would not be received by a peripheral (acting as client)
as gap_event_cb wasn't handling it. Now both central_gap_event_cb
and peripheral_gap_event_cb share the same common handler for these
events.

This commit fixes two issues on the esp32:
- it enables machine.soft_reset() to be called in main.py;
- it enables machine.reset_cause() to correctly identify a soft reset.
The former is useful in that it enables soft resets in applications that
are started at boot time. The support is patterned after the stm32 port.
This commit implements basic NVS support for the esp32. It follows the
pattern of the esp32.Partition class and exposes an NVS object per NVS
namespace. The initial support provided is only for signed 32-bit integers
and binary blobs. It's easy (albeit a bit tedious) to add support for
more types.

This enables -Os for compilation, but still keeps full assertion messages.
With IDF v4.2, -Os changes the GENERIC firmware size from 1512176 down to
1384640, and the GENERIC_SPIRAM firmware is now 1452320 which fits in the
allocated partition.

So that mboot can be used to program encrypted/signed firmware to regions
of flash that are not the main application, eg that are the filesystem.
