Hi,

I am trying to enable Wifi on imx7d-pico using mainline kernel. imx7d-pico
has an AP6335 chip.

I am facing some issues related to the nvram file. I am using the firmware
provided by Buildroot (brcmfmac4339-sdio.bin). I get the following error:

[    8.630380] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):
clkctl 0x50

I have tried to use the firmware and nvram provided by TechNexion but I get
the same error.

Is there anyone that could enable Wifi on AP6335 using kernel mainline?
What nvram file was used?

I am able to use Wifi on the board if I use the firmware, nvram file and kernel
provided by TechNexion. They use a 4.1 kernel from NXP with the bcmdhd
driver.

So I know that the hardware is functional.

Any suggestions as how to get it working with a 4.13 and brcmfmac driver is
appreciated.

Thanks!

Regards,
Vanessa
