Hi  jingyang

one can check if correct dev/mmcblk"x"p"y" was used and

check signals with oscilloscope. Try to test emmc from uboot.

Best regards

Hi,igor

    my emmc is 8G ,but when use mfgtool to download image into it ,the console prints as followed:

   mmc3: new MMC card at address 0001
   mmcblk3: mmc3:0001 16 1.00 GiB

why deos  the volume of emmc which the system check is different from the actual value ?

Hi  jingyang

please try to boot from other media, for example sd.

eMMC Partition by U-boot (i.MX53) 

kernel/git/torvalds/linux.git - Linux kernel source tree
