Hi All,
I use the DWMMC driver in u-boot mainline on exynos board and face the following issue.
I do a mmc rescan 3 times, then fourth time I get a DATA ERROR, which is due to FIFO underun/overun, after which I don't even get Command done interrupt. Later on the mmcinfo value also is displayed wrong.
Please do let me know if anybody have a solution for same.
You may know it already, can you try by enable CONFIG_MMC_TRACE on board config. so-that at-least we may come to know on which CMD this over/underrun occur.
Thanks, Jagan.
