Description

opened on May 2, 2025

Port, board and/or hardware

nrf port, PROMICRO board

MicroPython version

MicroPython v1.26.0-preview.59.g79abdad9e; PROMICRO with NRF52840

Reproduction

  1. Have nrf port v1.26.0-preview.59.g79abdad9e built and flashed (board PROMICRO in my case) onto an nRF52840 chip.
  2. Connect and reset the board to make sure it's running MicroPython and isn't busy.
  3. cd to tests and run ./run-tests.py -t /dev/ttyACM<port_number>.
  4. Some tests willl run just fine (like extmod/machine1.py), others should either be skipped or fail.
  5. In reality, this test will fail to fail and only hang.

Expected behaviour

Expected to pass this test. But this port probably doesn't support it yet.

Observed behaviour

$ strace ./run-tests.py -t dev/ttyACM0
