    1FX with imx6ulevk error - brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50

    RaSe_4140371

      Hi All,

       

      I am using Murata Interconnect adapter Version2(SDIO 60pin) with 1FX wifi module(connected via samtec connector) on my imx6ulevk baord.

       

      Board Type: IMX6UL EVK

      WiFi :- Murata 1FX

      Interconnect board : Version2(with Ribbon cable)

      Linux version: 4.14.78

       

      I'm trying to bring up the wifi module with brcmfmac driver but it showing the below error.

      root@imx6ulevk:~# modprobe -r brcmfmac                                                                                                    

      root@imx6ulevk:~# modprobe brcmfmac

      brcmfmac: brcmf_fw_map_chip_to_name: using brcm/brcmfmac43430-sdio.bin for chip 0x00a9a6(43430) rev 0x000001

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

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

       

      Is this happening because of LPO_IN crystal clock oscillator(32.768KHz)? I didn't see any oscillator in the 1FX module. Is that oscillator mandatory?

       

      Any suggestions, it will be helpful.

       

      Thanks in Advance
