We are using develop automobile product based iMX6Q sabresd board，we change the DDR with 2G size.
I have found some documents about DDR in community, it seems that I have to comiple MFG tool firmware for my board.
Related document, tood and source code:
There are desciptions about build mfgtool firmware in user guide section 3.9, but I found that uboot source code will only be downloaded when execute the command:
$ ./ltib --profile config/platform/imx/updater.profile --preconfig config/platform/imx/imx6q_updater.cf --continue --batch
and uboot source code will be removed after the command complete, I have no chance to modify the uboot source code.
So how to modify the uboot source code for mfg firmware and rebuild it?,
