[meta-freescale] [meta-freescale-3rdparty] pico-pi-imx7d wifi

[Måns Zigher]

So by copying using the following file
https://github.com/buildroot/buildroot/blob/master/board/technexion/imx6ulpico/rootfs_overlay/lib/firmware/brcm/brcmfmac4339-sdio.txt
I managed to get around the initial problem but now I see the following

[  306.862288] brcmfmac: brcmf_fw_map_chip_to_name: using
brcm/brcmfmac4339-sdio.bin for chip 0x004339(17209) rev 0x000002
[  307.923598] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):
clkctl 0x50
[  308.968299] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):
clkctl 0x50
[  309.988141] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):
clkctl 0x50

Since the txt file is not available only the bin file dose that mean it is
not supported? Do you have any information on the relationship with the txt
file and the chip, I mean I guess they need to match but is this a mater of
finding the specs for the chip and matching the parameters in the txt file?

Thanks
