SN8000 and iMX6ULevk

[gonfer]

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.

• In kernel I’ve enable brcmfmac driver, as described here: https://wireless.wiki.kernel.org/en/users/drivers/brcm80211?s[]=bcm43362
• In yocto I’ve added linux-firmare recipe
• I’ve created /lib/firmware/brcm/bcm43362-bin.txt following this guide: http://wireless.murata.com/RFM/data/sn8000_sn8000ufl_nvram.pdf
• Following this thread https://community.freescale.com/message/506774#506774 I’ve also checked:
  • VDD_BAT and VDD_IO pin to be at 3.3
  • VDD_3V3_EN to be 3.3V

dmesg related output is:

….....................

What am I missing? Any hints are appreciated !!

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 ?
