brcmfmac WiFi for BCM4339 not working, wand board

Postby farlies » Sun Aug 22, 2021 9:40 pm

The Wi-Fi adapter for my Wand Quad board (Rev D1) seems to be unusable via brcmfmac -- no interface appears.

The SDIO device is discovered:
$this->bbcode_second_pass_code('', '
*-device

')

The bluetooth side seems to be recognized.
The module loads, per lsmod:

$this->bbcode_second_pass_code('', '
brcmutil 20480 1 brcmfmac
cfg80211 372736 1 brcmfmac
brcmfmac 290816 0
')

but a few worrisome kernel messages appear:

$this->bbcode_second_pass_code('', '
[ 12.297170] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac4339-sdio.wand,imx6qp-wandboard.txt failed with error -2
[ 12.309053] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac4339-sdio.txt failed with error -2
[ 13.336030] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
')

The nvram firmware file brcmfmac4339-sdio.bin exists in /lib/firmware/brcm (link to ../cypress/), but the '.txt' files noted in the messages above are nowhere to be found. So far, no luck finding any of those on the net. Maybe they aren't strictly required, and I'm missing some other key configuration step?
Is there a guide somewhere for creating the missing file?

Any suggestions welcome...
