I just upgraded uboot using dd and it boot successfully :
dd if=uboot_file of=/dev/mmcblk0 bs=512
The output is :
1360+1 records in 1360+1 records out
I would like to read backup to ensure every bit is written successfully. I tried to use :
dd of=uboot_check if=/dev/mmcblk0 count=1360
The content of uboot_check is nearly completly full of 0 instead of getting the uboot image back.
Any idea ? Thanks
