Trouble in Flashing to eMMC using USB blaster

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/documentation/a10gsrd161nandboot?validation_key=d0d54f947c8f6494547938d664df12c1)

Debug messages:

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

Thank you.
