It wasn't being run due to a rework done only on the atmel-samd port.
The rework itself isn't needed now that the heap check triggers safe
mode instead of throwing a Python exception. So, I've removed the
rework.
This creates a common safe mode mechanic that ports can share.
As a result, the nRF52 now has safe mode support as well.
The common safe mode adds a 700ms delay at startup where a reset
during that window will cause a reset into safe mode. This window
is designated by a yellow status pixel and flashing the single led
three times.
A couple NeoPixel fixes are included for the nRF52 as well.
Fixes#1034. Fixes#990. Fixes#615.
The backtrace cannot be given because it relies on the validity
of the qstr data structures on the heap which may have been
corrupted.
In fact, it still can crash hard when the bytecode itself is
overwritten. To fix, we'd need a way to skip gathering the
backtrace completely.
This also increases the default stack size on M4s so it can
accomodate the stack needed by ASF4s nvm API.
This started while adding USB MIDI support (and descriptor support is
in this change.) When seeing that I'd have to implement the MIDI class
logic twice, once for atmel-samd and once for nrf, I decided to refactor
the USB stack so its shared across ports. This has led to a number of
changes that remove items from the ports folder and move them into
supervisor.
Furthermore, we had external SPI flash support for nrf pending so I
factored out the connection between the usb stack and the flash API as
well. This PR also includes the QSPI support for nRF.
This enables various things in order to support the CPython standard library.
MICROPY_PY_BUILTINS_NOTIMPLEMENTED:
Support NotImplemented for easy conversion of stdlib.
It doesn't do fallbacks though, only raises TypeError.
MICROPY_PY_COLLECTIONS_ORDEREDDICT:
collections.OrderedDict
MICROPY_PY_FUNCTION_ATTRS:
Support function.__name__ for use as key in the function attribute workaround.
MICROPY_PY_IO:
uio module: BytesIO, FileIO, StringIO, TextIOWrapper
Also add 'io' alias.
MICROPY_PY_REVERSE_SPECIAL_METHODS:
Support the __r*__ special methods.
MICROPY_PY_SYS_EXC_INFO:
sys.exc_info() used by unittest when collecting exceptions.
MICROPY_CPYTHON_COMPAT:
Some of the things it adds:
>>> object.__init__
<function>
>>> object.__new__
<function>
>>> object.__class__
<class 'type'>
>>> object().__class__
<class 'object'>
>>> object.__name__
'object'
>>> 'Hello'.encode()
b'Hello'
>>> b'Hello'.decode()
'Hello'
Named tuple field names from string:
namedtuple('Point', 'x y')
