I used the rt818etv wireless network card test, and the SDK(ti-sdk-am335x-evm-07.00.00.00) integration driver was used, and the following errors were reported after repeated hot insertion.
so,I also tested it in the latest SDK(ti-processor-sdk-linux-rt-am335x-evm-04.01.00.06), tt will still cause the kernel to crash
What should I do?
