We are trying to use new mfgtool v3.0 (uuu) on IMX7D Sabre board. With existing firmware file we are not able to download new binaries to Sabre board. It seems we need new firmware files for this.
If someone have already tried building new firmware to support UUU tool, it will be very helpful if you can share steps.
Also if any prebuilt firmware files are there please share.
