Gibbs Shih

Part Number: TDA4VM

Hi, Expert :

Because of changing Ethernet phy chip (KSZ9031), we need try to re-configure u-boot and compiler boot binary code

Rules.mk define u-boot configuration, and I'm very sure it reference these files.

in "/ti-processor-sdk-linux-automotive-j7-evm-07_00_01/Rules.mk"

#u-boot machine
UBOOT_MACHINE=j721e_evm_a72_config

UBOOT_MACHINE_R5=j721e_evm_r5_config

my questons is "where is j721e_evm_a72_config & j721e_evm_r5_config"  files?

Many Thanks

Gibbs

    Hi Gibbs,

    You are right the r5 SPL Config file is: j721e_evm_r5_config & A72 SPL/ub-boot Config file is: j721e_evm_a72_config.

    In the SDK install path these files are present in the folder:

    $SDK_PTH/board-support/u-boot-2020.01+gitAUTOINC+f9b0d030d3-gf9b0d030d3/configs/

    Please resolve this query in case you have no further questions on this.

    Best Regards,
    Keerthy

    Hi, Keerthy :

    follow your comment, 

    >> $SDK_PTH/board-support/u-boot-2020.01+gitAUTOINC+f9b0d030d3-gf9b0d030d3/configs/

    this folder just include "j721e_evm_a72_defconfig" and  "j721e_evm_r5_defconfig"

    that's different.

    so, this is my question point

    Many Thanks

    Gibbs,

    u-boot compiles if you give j721e_evm_r5_defconfig or j721e_evm_r5_config.

    You can try that on your setup. Also to double check we can simple rename j721e_evm_r5_defconfig file to temp and you
    can see that compilation fails.

    Bottomline is j721e_evm_r5_defconfig is the config file for R5 and j721e_evm_a72_defconfig for A72.


    Hope it is clear.

    Best Regards,
    Keerthy

    Hi, Keerthy :

    Follow previous thread loop :

    >>You can try that on your setup. Also to double check we can simple rename j721e_evm_r5_defconfig file to temp and you
    >>can see that compilation fails.

    you are right, I rename j721e_evm_r5_defconfig & j721e_evm_a72_defconfig, get some errors!

    Many Thanks
