Привет, я скомпилировал ядро с включенной поддержкой comedi. Я использую это руководство от jetsonhacks:
https://www.jetsonhacks.com/2018/03/22/build-kernel-modules-nvidia-jetson-tx2-2/
В настоящее время я установил Comedilib и скомпилировал некоторые из их примеров программ. Для / dev / comedi0 используется правильный драйвер, однако, когда я запускаю какой-либо из них, выходных данных нет, и экземпляр bash зависает. Я проверил вывод dmesg, и он содержал эту строку:

Любая помощь будет оценена заранее спасибо.
