Hi,

Board used: IMX6SXSABRESD
Kernel image: It's yocto build  based on latest IMX yocto project user guide
kernel version: 4.9.88

After a fresh boot up, SDIO card is inserted into SDIO 3.0 slot(J3) of the board.

It's showing up the SDIO initialization messages and unable to detect the card

Please find the attached log files.
bootlog.txt: Contains the kernel bootup prints
sdio_init_failure.txt: It's a sdio card detection failure log


Thanks,

venkatesh

Hi venkatesh

for sd3 one can check linux/arch/arm/boot/dts/imx6sx-sdb-btwifi.dts

imx6sx-sdb-btwifi.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel 

supported wifi modules are described on

wireless.murata.com/eng/products/rf-modules-1/wi-fi-bluetooth-for-freescale-i-mx.html

For other modules one will have to ask driver from module vemdor for Linux L4.9.88.

Best regards
igor
