Hi all,

I’m trying to get a SN8000CMD module working on a iMX6ULevk but I’m facing some issues. The evk is running fsl-image-multimedia.

dmesg related output is:

….....................

mmc0: no vqmmc regulator found

mmc0: SDHCI controller on 2190000.usdhc [2190000.usdhc] using ADMA

mmc0: queuing unknown CIS tuple 0x80 (7 bytes)

mmc0: queuing unknown CIS tuple 0x80 (6 bytes)

mmc0: queuing unknown CIS tuple 0x80 (8 bytes)

mmc0: queuing unknown CIS tuple 0x80 (2 bytes)

mmc0: queuing unknown CIS tuple 0x80 (7 bytes)

mmc0: queuing unknown CIS tuple 0x80 (5 bytes)

mmc0: new high speed SDIO card at address 0001

….....................

….....................

brcmfmac: brcmf_bus_start: brcmf_sdbrcm_bus_init failed -19

brcmfmac: brcmf_sdio_probe: dongle is not responding

brcmfmac: brcmf_ops_sdio_probe: F2 error, probe failed -19...

….....................

What am I missing? Any hints are appreciated !!

Regards,

Gonzalo

Hello Gonzalo Fernandez,

Did you measure some signal of  Enable pin and Reset pin of wifi module ? Please check your "WL_REG_ON" signal.

And how about your DTB configuration  of  Wifi relevant pin for this Murata wifi module ?
