Hi Fsl,

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:

1. Mfgtools-Rel-4.1.0_130816_MX6Q_UPDATER.

2. i.MX_6Dual6Quad_SABRE-SD_Linux_User's_Guide.pdf

3. L3.0.35_4.1.0_130816_source

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/ --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?,
