Hi all, 

 

I am trying get wifi working on Nanopi neo air with the Mainline kernel v4.12.12. I enabled brcmfmac driver in the kernel.  Downloaded the corresponding firmware(brcmfmac43430-sdio.bin) for AP6212 from : https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/brcm.  I have applied patch to the device tree to enable wifi (https://www.spinics.net/lists/arm-kernel/msg563666.html)

 

I couldn't get the firmware loaded properly.  Here's the log.

Should I be trying some different firmware? 

Any input is much appreciated. Thank you.

splited, from original thread because different topic

Wi-fi worked after I copied the firmware file from the legacy kernel to the mainline kernel and renamed it to brcmfmac43430-sdio.bin

Please do let me know if there is a better solution. Thank you.
