LS1012ARDB Murata wifi SN8000 load module failed

[miftahul_huda]

Hello Experts,

I have LS1012ARDB board with ls1012ardb_ask_8.0.0-B1 installed on it. 

I have problem while loading murata wifi driver, mostly it will fail to load the driver, and I need to reboot the board and try to load the driver module again until success. Here is the error message

# insmod /lib/modules/4.9.73/bcmdhd.ko nvram_path=/lib/firmware/bcmdhd.SN8000.SDIO.cal firmware_path=/lib/firmware/fw_bcmdhd.bin

I also attach boot message.

What make the driver installation failed?
What should I do to prevent this happening?

Best regards,

Huda

Hi yipingwang 

From this thread https://community.nxp.com/t5/i-MX-Processors/SD2-card-slot-is-not-working-for-WiFi/m-p/232016

From log messages, It seems that mmc1 didn't find new attached device(wifi) at the beginning, So could you try to power up wifi in BSP file ? At first, we should ensure mmc controller can find wifi

I am not clear about "BSP file", where could I find it? Is it accessible in OpenWRT? Since I only have the board LS1012ARDB, prebuilt firmware ls1012ardb_ask_bhr_8.0.0-B1, and OpenWRT 18.06 to build package that compatible for firmware ls1012ardb_ask_bhr_8.0.0-B1. If it not, what should I do to obtain it?

Best regards,

Huda
