AM6548: Building Linux from git repo

Part Number: AM6548


Hi TI,

I am trying to download the linux tar image from the git repo as suggested in TI SDK release note.

link to git : https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/refs/tags

as suggested in SDK 7.01.0.17 release notes I am downloading tag : 07.01.00.006 

This tag is suggested in release notes: https://software-dl.ti.com/processor-sdk-linux/esd/AM65X/07_01_00_17/exports/docs/devices/AM65X/linux/Release_Specific_Release_Notes.html

After downloading this linux repo I am not able to find the tisdk_am65xx-evm_defconfig file in /arch/arm64/configs

Is this correct linux tag that I am downloading for the SDK 7.01.0.17

Thanks,

Sarfaraz

    Hi Sarfaraz,

    cd $LINUX_DIR

    ./ti_config_fragments/defconfig_builder.sh
         1. v7 ARM Architecture
         2. v8 ARM Architecture

    Please choose an architecture to build for or 'q' to exit: 2
         1. SDK_Debug_Defconfigs
         2. SDK_Release_Defconfigs

    Please choose a defconfig type to build for or 'q' to exit: 2
    Available SDK_Release_Defconfigs defconfig build options:

        1. ti_sdk_arm64_release

    Please enter the number of the defconfig to build or 'q' to exit: 1
    Creating defconfig file /home/keerthy/work/ti-linux-kernel/arch/arm64/configs/ti_sdk_arm64_release_defconfig

    You will not get tisdk_am65xx-evm_defconfig.

    So you can try:

    make ARCH=arm64 ti_sdk_arm64_release_defconfig

    This will also build AM65 dtb.

    Best Regards,
    Keerthy

    The difference between ti_sdk_arm64_release_defconfig and tisdk_am65xx-evm_defconfig is quite large , can I directly use tisdk_am65xx-evm_defconfig instead of ti_sdk_arm64_release_defconfig  after downloading linux from above link?

    Will this work fine for SR2 boards

    Hi Sarfaraz,

    You could try that and let me know. I am not sure why you want to use the git repo Vs SDK. SDK gives you all
    that is needed for compiling.
