Description

Above is the serial output via tio for one example run. You can ping about 8-10 times, then it HardFaults.

The same code with time.sleep(1) does not seem to crash.

This happens on both ESP32-S2 and ESP32-S3, on both 7.3.3 and 8.0.0-beta0.

Additional information

This was originally reported by @Wind-stormger here todbot/circuitpython-tricks#10

[Wind-stormger]

Thanks for testing again.

Is this distinct from #5980?

[todbot]

Yep, this is a dupe of 5980, with the only addition is that it is still a problem in 8.0 and on ESP32-S2 and ESP32-S3.

I will close this issue. Apologies, I didn't search hard enough in existing issues before submitting this one.

[anecdata]

Tod would you mind commenting with the updated findings?

There's an older ping issue on Espressif, but it's closed espressif/esp-idf#5202

[todbot]

You mean leave a comment in 5980 with 8.0 & S2/S3 info?

[anecdata]

Please, yes, that would bring the comments up to date.
