Ap6255 is currently used on the IMx8 Mini. It is found that the driver of this part is already available on the kernel using 4.1.98. It can be started normally just by configuring the relevant device tree.But now the problem is that I used the IW command to connect to wifi without password, but I reported an error when I used wPA_supplicant to connect to wifi with password,Using iwConfig will also report an error.Do I need to modify the driver or is there any way to solve this problem.Here are some of the error messages. Thank you
