@luz I tried to understand the script. I am making a testing fixture with raspberry pi 3 as host system, where i want to run script similar to yours one. And firmware file will be inside root directory In your script can you explain how i can bring firmware file. omega2flash <eth0> <auto|wait|omega2_ipv6|list|ping> [</root/Omega2SP_Custom.bin> [<uboot-env-file>]] Is above method is correct ?
