Other Parts Discussed in Thread: OMAPL138

Hi,

I am trying to bring up the SDIO interface. CMD0 is OK. But there is always a response CRC error for CMD5.

Any suggestion?

Thanks,

    Hi Halin,

    Thanks for your post.

    But, unfortunately, there are no examples, drivers support in BIOS PSP or starterware of SDIO to try with to debug this issue. The only thing for you to try with is on ARM side SDIO as part of WLAN in the Linux SDK for OMAPL138 to benchmark this.

    We do suggest using the SDK for WLAN since WLAN is verified only in SDK context. We in PSP do integrate kernel patches from WLAN folks when they are submitted to us, but we don’t exercise the WLAN functionality.

    Thanks & regards,
