In 9.0.x, serial_bytes_available returned a bool and tud_cdc_available was
harmlessly checked twice for any characters.
When the routine was changed to return an int, the double checking led to
over-reporting the number of characters available. In code that would attempt
to read this many bytes from sys.stdin, this made the read call block since
only 1 byte was actually available.
This behavior came up in the discussion of #9393. I don't mark this bug as
closing that one, because that issue seems to be reporting multiple things that
this change would not address, such as delays in `sys.stdout.write()` or
problems seen while using webserial.
The previous implementation would always start BLE and rely on
advertising logic to make the workflow not available when on USB.
This change removes the "always enable" call in favor of a default
value that is on if 1) we determine we should be discoverable or 2)
we're already bonded over BLE.
This runs in the Renode simulator and enables easier tracing and
debugging of the CircuitPython core. This port can also serve as
a starting point for new ports because it implements the minimal
necessary for the CP core to run.
It is enabled on:
* SAMD51 boards with 1MB flash (SKU ending in 20A)
* Feather RP2040 DVI. Others have PIO usb host.
* All ESP32 boards.
* All nRF boards
Fixes#8676
The guard against running when flash is disabled isn't perfect and
may lead to calling the row handler anyway. We were crashing due
to mp_hal_delay_us being in flash. So, move it to RAM.
Also move the panic handler to IRAM so we get nice output when this
happens.
Turn off JTAG by default so its pins can be used by code.py.
Fixes#8987
I tested this by fetching a .txt file repeatedly using curl while
running the fancy camera demo. (100+ times without failure). I also
repeatedly loaded the filesystem view http://.../fs/#/sd/ which worked
10+ times without failure, but does take some time (multiple seconds) to
show a listing with a few dozen files.
(I suspect there's an accidentally quadratic behavior in oofatfs to stat
every file in a directory, because it repeatedly does a linear search of
the directory for the stat information of each file, but that's not an
issue for Right Now(TM))
Closes: #8980
- add tuh_event_hook_cb() in SRAM, required when updated to latest tinyusb
- bump up pico-pio-usb to latest
- bump up tinyusb to latest for new tuh_hid_receive_abort(), and all endpoint abort when
