Hi Martin,

Timeout cmd id (1584563353.27844) = 0xa9, act = 0x0
This shows that there is no reply to the first command sent in
mwifiex_sta_init_cmd()
There is a possibility that the firmware has responded to this command but the SDIO interrupt gets stuck somewhere.
Are you able to hook up an oscilloscope to check whether SDIO DAT1 pin stays low or not?
Indeed,
DAT1 goes low after the command is sent and stays low until the card is
reset.
No SDIO interrupts are received by the host controller (i.MX53)
So it looks like a host controller issue - right?
Regards,
Martin
