Hello Arend,

I've A83T BPI-m3 board, which includes AP6212(brcm43430). I'm trying
to make it work for mainline linux and brcm driver.

After enabling mmc1, It could read vendor: 0x02d0 device: 0xa9a6. from
/sys/bus/mmc/devices/mmc1:0001/mmc1:0001:1

BRCM driver loads the firmware files, however, it gives below errors
and wlan0 is not available:

dmesg | grep brcm
[    1.187459] brcmfmac: brcmf_of_probe: interrupt could not be mapped
[    1.194419] brcmfmac: F1 signature read @0x18000000=0x1530a9a6

[    3.319433] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):
clkctl 0x50
[    4.349022] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):
clkctl 0x50


There are no brcm43430 firmware files at
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/brcm
So, used firmware:
https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm80211/brcm/brcmfmac43430-sdio.bin
and .txt.

Could you please help me in this regard ?


Regards,
Vishnu
