Sincerely yours,

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

We are not familiar with auvidea j121 board. rel-32.1 is kind of old. Do they provide new release?

Share the dmesg may help know your problem.

Sorry for the late reply, I solved my problem flashing my card with the SDK manager.
