Other Parts Discussed in Thread: AM625,
I am facing a Linux driver crash issue with the CC33xx. The Linux kernel version used is 6.1.119-ti, and the CC33xx driver version is 1.0.2.10. What could be the reason for this error? Normally, the CC33xx works fine, I can connect and send data using both Wi-Fi and BLE, but this error occurs sometimes.
