DRA821U: U-boot help/config files

Luke
Expert 3120 points
Part Number: DRA821U

Tool/software:

Hi team,

Where could I find the entire list of config files for the DRA821U and which file is used for the common directory?

My customer says that Common/board_r.c is not taking config options from either configs/j7200_evm_a72_defconfig or j7200_evm_r5_defconfig.

They are working around this problem for POST development but will also need this for R5 memory diagnostics.

Best,

Luke

    This is the correct defconfig for R5 SPL configuration.

    The customer can double check by generating the .config file from the defconfig.

    make j7200_evm_r5_defconfig

    Will generate .config file and check if all the dependencies for the configs are met properly.

    Best Regards,

    Hi Keerthy,

    That helped as I was able to track down the config file that is built.

    I added a new config option to configs/j7200_evm_a72_defconfig and it does not show up in what’s built. I was able to remove an option and it correctly doesn’t show up in the build.

    Seems there is some procedure to follow to add a new config flag. Is this correct and what would it be?

    Thanks,

    Luke

    You will need to check the corresponding CONFIG under the KCONFIG file where it is defined and make sure all the dependencies are set.
