Hi All,

We are trying flash the binaries to eMMC using USB-Blaster II

When I executed the below command it ends up with errors:
./flash_programmer.py --operation=epv --address=0x00000000 --size=0x00100000 --file=<path>/uboot_w_dtb-mkpimage.bin
(refered as in link https://rocketboards.org/foswiki/Doc...7938d664df12c1)

What could have caused this error? Has anyone faced the same problem before??

Thank you.
