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
