Hi ALL,
I am using TI DM320 to develope SDIO WiFi driver.
At first, I wrote one SD memory card driver and it work fine.
Currently, I try to port my SD controller driver to support SDIO
function.
BUT, CRC error displayed when I insert my SDIO WiFI card. The SDIO card
is workable at other PDAs.
I check the detail debug log, the CRC error is occurred at CMD5-R4
responds from sdio card. Following are detail log.
Could anyone know what's happen?
