`gpio:stop/0` on esp32 causes VM crash #816

Closed UncleGrumpy closed 8 months ago

UncleGrumpy commented 1 year ago

I have deleted the AtomVM/build and AtomVM/src/platforms/esp32/build directories and done a complete clean rebuild of the esp32 image several times. The following is the simplest way to reproduce the crash is:

start() ->
    _GPIO = gpio:start(),
    timer:sleep(500),
    io:format("Stopping GPIO driver.~n"),
    gpio:stop().

For some reason I have not had stack traces with the last several rebuild of the image either, but the output is similar to:

AtomVM init.

Here is idf.py monitor output of the crash when gpio:stop() is called:

...
