imx8 mini ap6255 unable to connect to password-protected wifi

[fu_qiang]

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

Hi fu

i.MX8M Mini was not supported by nxp in kernel 4.1.98, suggest to try latest

from source.codeaurora.org/external/imx/linux-imx repository
linux-imx - i.MX Linux kernel 

Embedded Linux for i.MX Applications Processors | NXP 

latest brcmfmac drivers:

Cypress Linux WiFi Driver Release (FMAC) [2020-... | Cypress Developer Community 

Best regards
igor

Sorry, I made a mistake. The current version is 4.14.98. The system is currently operating normally.
