Interfacing FPGA SDIO interface with imx6 SD3

[shammi112]

Hello,

We are  trying to interface FPGA using sdio interface on imx6 sd3 interface. But imx6 is not able to detect FPGA SLAVE device. we are getting the below errors.

43.136538] mmc1: queuing unknown CIS tuple 0x01 (0 bytes)
[ 56.955815] mmc1: error -22 whilst initialising SDIO card
[ 59.026637] mmc1: error -110 whilst initialising SDIO card
[ 61.096092] mmc1: error -110 whilst initialising SDIO card
[ 63.166095] mmc1: error -110 whilst initialising SDIO card

Most likely, it means that your FPGA is not configured properly to be recognized as an SDIO device. Please check your FPGA configuration first.

Have a great day,
