Because DMA2 may be in use by other peripherals, eg SPI1.
On PYBD-SF6 it's possible to trigger a bug in the existing code by turning
on WLAN and connecting to an AP, pinging the IP address from a PC and
running the following code on the PYBD:
def spi_test(s):
while 1:
s.write('test')
s.read(4)
spi_test(machine.SPI(1,100000000))
This will eventually fail with `OSError: [Errno 110] ETIMEDOUT` because
DMA2 was turned off by the CYW43 driver during the SPI1 transfer.
This commit fixes the bug by removing the code that explicitly disables
DMA2. Instead DMA2 will be automatically disabled after an inactivity
timeout, see commit a96afae90f

Quail (https://www.mikroe.com/quail, PID: MIKROE-1793) is based on an
STM32F427VI CPU, featuring 2048 kB of Flash memory and 192 kB of RAM. An
on-board Cypress S25FL164K adds 8 MB of SPI Flash.
Quail has 4 mikroBUS(TM) sockets for Mikroe click(TM) board connectivity,
along with 24 screw terminals for connecting additional electronics and two
USB ports (one for programming, the other for external mass storage).
4 UARTs, 2 SPIs and 1 I2C bus are available for communication.

Was incorrectly added as 7MB for an 8MB SPI flash, but this board has a
16MB chip, not 8MB, so it should be 15MB leaving 1MB for MicroPython.

The rp2.StateMachine.exec errors when supplying a sideset action. This
commit passes the sideset_opt from the StateMachine though to the parser.
It also adds some value validation to the sideset operator.
Additionally, the "word" method is added to the exec to allow any other
unsupported opcodes.
Fixes issue #7924.
- Makefile: update to use new ASF4 files, support frozen manifest, and
include source files in upcoming commits
- boards/manifest.py: add files to freeze
- boards/samd51p19a.ld: add linker script for this MCU
- help.c: add custom help text
- main.c: execute _boot.py, boot.py and main.py on start-up
- modules/_boot.py: startup file to freeze
- modutime.c: add gmtime, localtime, mktime, time functions
- mpconfigport.h: enabled more features for sys and io and modules
- mphalport.h: add mp_hal_pin_xxx macros
- mphalport.c: add mp_hal_stdio_poll
Don't force the 'HAL' string to be part of the platform string because
it doesn't have a sensible meaning for all possible platforms, and
swap it with the PLATFORM_ARCH string so the strings which most platforms
have come first.
Although the pyboard has only 4 LEDs, there are some boards that (may) have
more. This commit adds 2 more LEDs to the led.c file that if defined in
the board-specific config file will be compiled in.
This commit swaps the dimensions of the `framebuffer.FrameBuffer` in the
docs example from 10x100 to 100x10 pixels to avoid clipping.
This is done to better fit the subsequent example code, which writes
text of size 96x8 followed by a 96x1 horizontal line.
The y coordinate of the horizontal line is also adjusted such that it is
drawn inside of the new canvas bounds.
Expected result of const.py will be matched only when MICROPY_COMP_CONST is
enabled. For easy understanding, added description at the first of the
test code.
Some toolchains will have string.h defining various macros which can lead
to compile errors for string function implementations. Not including
string.h fixes this.
An implementation of __memcpy_chk is provided for toolchains that enable
_FORTIFY_SOURCE.
Fixes issue #6046.

- Add board.md files for MIMXRT1060_EVK and MIMXRT1064_EVK warning about
their experimental state.
- Add separate deploy_teensy.md and deploy_mimxrt.md files.
The ARCH MIX board exposes the Ethernet Pins at it's connectors. Therefore
the software is configured for using a LAN8720 PHY device. Breakout boards
with the LAN8720 are easily available.
This commit adds I2S protocol support for the rp2 port:
- I2S API is consistent with STM32 and ESP32 ports
- I2S configurations supported:
- master transmit and master receive
- 16-bit and 32-bit sample sizes
- mono and stereo formats
- sampling frequency
- 3 modes of operation:
- blocking
- non-blocking with callback
- uasyncio
- internal ring buffer size can be tuned
- DMA IRQs are managed on an I2S object basis, allowing other
RP2 entities to use DMA IRQs when I2S is not being used
- MicroPython documentation
- tested on Raspberry Pi Pico development board
- build metric changes for this commit: text(+4552), data(0), bss(+8)
