I am developing a card based on i.MX535 processor. All seem good, but I encountered a problem with µSD on slot SD1. When U-boot tries to load Linux kernel image from the µSD to DDR, we have the message "set read bl len failed".
I tried to rescan the µSD (mmc rescan 0), but it fails.
Any idea ?

Are you able to see some clock signal comming out from SD interface after the mmc rescan command?. You could use a scope for this.
Try to use another device number on the SD.
