The pyb.Flash() class can now be used to construct objects which reference
sections of the flash storage, starting at a certain offset and going for a
certain length. Such objects also support the extended block protocol.
The signature for the constructor is: pyb.Flash(start=-1, len=-1).
This commit refactors and generalises the boot-mount routine on stm32 so
that it can mount filesystems of arbitrary type. That is, it no longer
assumes that the filesystem is FAT. It does this by using mp_vfs_mount()
which does auto-detection of the filesystem type.
The address, adv payload and uuid fields of the event are pre-allocated by
modbluetooth, and reused in the IRQ handler. Simplify this and move all
storage into the `mp_obj_bluetooth_ble_t` instance.
This now allows users to hold on to a reference to these instances without
crashes, although they may be overwritten by future events. If they want
to hold onto the values longer term they need to copy them.
Using mp_hal_delay_ms allows the scheduler to run, which might result in
another transmit operation happening, which would bypass the sleep (and
fail). Use mp_hal_delay_us instead.
The compile-time configuration value MICROPY_HW_RTC_USER_MEM_MAX can now be
used to define the amount of memory set aside for RTC.memory(). If this
value is configured to zero then the RTC.memory functionality is not
included in the build.
Remove existing scan result events from the ringbuf if the ringbuf is full
and we're trying to enqueue any other event. This is needed so that events
such as SCAN_COMPLETE are always put on the ringbuf.
The IDF heap is more fragmented with IDF 4 and mbedtls cannot allocate
enough RAM with 16+16kiB for both in and out buffers, so reduce output
buffer size.
Fixes issue #5303.
This commit removes the Makefile-level MICROPY_FATFS config and moves the
MICROPY_VFS_FAT config to the Makefile level to replace it. It also moves
the include of the oofatfs source files in the build from each port to a
central place in extmod/extmod.mk.
For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1
at the level of the Makefile. This will include the relevant oofatfs files
in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.
defindex.html (used by topindex.html) is deprecated, but topindex.html was
already identical other than setting the title, so just inherit directly
from layout.html.
This commit adds support for littlefs (v2) on all esp32 boards.
The original FAT filesystem still works and any board with a preexisting
FAT filesystem will still work as normal. It's possible to switch to
littlefs by reformatting the block device using:
import uos, flashbdev
uos.VfsLfs2.mkfs(flashbdev.bdev)
Then when the board reboots (soft or hard) the new littlefs filesystem will
be mounted. It's possible to switch back to a FAT filesystem by formatting
with uos.VfsFat.mkfs(flashbdev.bdev).
While the new manifest.py style got introduced for freezing python code
into the resulting binary, the old way - where files and modules within
ports/*/modules where baked into the resulting binary - was still
supported via `freeze('$(PORT_DIR)/modules')` within manifest.py.
However behaviour changed for symlinked directories (=modules), as those
links weren't followed anymore.
This commit restores the original behaviour by explicitly following
symlinks within a modules/ directory
This commit adds a sys.implementation.mpy entry when the system supports
importing .mpy files. This entry is a 16-bit integer which encodes two
bytes of information from the header of .mpy files that are supported by
the system being run: the second and third bytes, .mpy version, and flags
and native architecture. This allows determining the supported .mpy file
dynamically by code, and also for the user to find it out by inspecting
this value. It's further possible to dynamically detect if the system
supports importing .mpy files by `hasattr(sys.implementation, 'mpy')`.
Replace the is_running field with a tri-state variable to indicate
running/not-running/pending-exception.
Update tests to cover the various cases.
This allows cancellation in uasyncio even if the coroutine hasn't been
executed yet. Fixes#5242
This wasn't necessary as the wrapped function already has a reference to
its globals. But it had a dual purpose of tracking whether the function
was currently running, so replace it with a bool.
