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

Hi,

Trying to get the wifi up on the pico-pi-imx7d. When using Technexion Yocto
flavor they build a driver bcmdhd while the community build a driver
brcmfmac. The community driver fail during boot

[    9.145319] brcmfmac: brcmf_fw_map_chip_to_name: using
brcm/brcmfmac4339-sdio.bin for chip 0x004339(17209) rev 0x000002
[    9.320044] brcmfmac mmc0:0001:1: Direct firmware load for
brcm/brcmfmac4339-sdio.txt failed with error -2

What are we looking at here? Do we need to port the bcmdhd driver to the
community kernel or is it a mater of fixing the brcmfmac driver? Why is
there two drivers for the same chip 4349?

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
