We are doing sdio brcm4339 chip wifi test on i.MX8M EVK from NXP, board is based on android 8.1 from NXP.
wifi driver (bcmdhd.ko) is from android 8.1 kernel. if insmod bcmdhd.ko, MMC code will meet crash. we don't make any modification to kernel code in android 8.1. could you tell me that i.MX8M board support sdio wifi?
crash log is below:
