Hi,

On a mx28evk board I am getting the following using top of tree U-boot:

U-Boot 2012.04-rc1-00001-g037cbfd (Apr 02 2012 - 10:57:48)

Freescale i.MX28 family at 454 MHz DRAM: 128 MiB MMC: MXS MMC: 0 MMC0: DMA transfer failed MMC0: DMA transfer failed MMC0: DMA transfer failed MMC0: DMA transfer failed MMC init failed Using default environment

Is there any patch I am missing?

Hi Fabio,

maybe it is worth to check first if it depends on the data cache, that is now turned on. Add CONFIG_CMD_CACHE to the configuartion file, and try to start mmc with and without dcache.

The cache should be off on m28evk and so should be on mx28evk.

Best regards, Stefano
