I trying to bring up SDIO host controller on Sabrelite IMX board on QNX. Have issue CMD5 had an successful response also send CMD3 had got positive response but Bit 19 was set in Response R6. After CMD3 when i send CMD7 iam getting timeout error and i see no response all the CMD52 are timing out.

Have no clue where things are going bad argument for CMD7 is rca << 16 where rca is 1. Please let me known is there any additional thing has to be done in case of QNX.

Regards

Hi kaushik,

About the BSP on QNX, you need to contract the QNX company and ask help from them. Our freescale do not provide QNX BSP. Hope this can help you ~~

Best Regards,

Dan
