I now need to burn the app firmware and modem firmware of multiple 9160 chips at the same time. Using pynrfjprog to write a program to burn the firmware for ten chips(Open ten threads to burn ten chips).
use：python3.8.3 pynrfjprog-10.11.1
When I start ten threads to burn, the program often exits automatically when burning app firmware or modem firmware. VScoede debugging did not report any errors, the program looks like it shuts down normally. I cannot locate my error right now. Is there any way I can find the error.
notes：
When I turn on the debug log, the console output log increases, resulting in longer burning time and the problem cannot be reproduced
logger = logging.getLogger() logger.setLevel(logging.DEBUG)
The last log on exit:
