This utility sends memcopy DDCBs to the application chip unit. It can be used to check the cards health and/or to produce stress on the card to verify its correct function.

Example:

dd if=/dev/urandom bs=4096 count=1024 of=input_data.bin ./genwqe_memcopy -C0 -F -D --patternfile input_data.bin output_data.bin echo $? diff input_data.bin output_data.bin echo $?
