One more question. I looked up the board you mentioined. What I found
has a dedicated SDIO slot for Wifi. Are you using that and do you know
if that is an SDIO3.0 or not? Earlier in the thread i found this logging:
> root@imx6slevk:~# mmc0: queuing unknown CIS tuple 0x91 (3 bytes)
> mmc0: new high speed SDIO card at address 0001
I think it means it is a SDIO2, but I like to be sure.
