[FAQ] Compiler/TDA2E: The steps to enable the early-boot late attach use-case in vision SDK 3.8 Linux

Hi,

Refer to the below thread.

Follow all the steps mentioned in the above thread except the below steps.

• Download the vision SDK

cd ~/

/* Download the SDK */

wget  https://software-dl.ti.com/processor-sdk-vision/esd/TDAx/vision-sdk/03_08_00_00//exports/PROCESSOR_SDK_VISION_03_08_00_00_setuplinux.bin

chmod +x PROCESSOR_SDK_VISION_03_08_00_00_setuplinux.bin

/* Recommending to install the SDK in the home directory [ /~ ] */

./PROCESSOR_SDK_VISION_03_08_00_00_setuplinux.bin

• Install the A15 compiler, Linker

cd ~/PROCESSOR_SDK_VISION_03_08_00_00/ti_components/os_tools/linux/arm/

wget https://developer.arm.com/-/media/Files/downloads/gnu-a/8.3-2019.03/binrel/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf.tar.xz

tar -xvf gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf.tar.xz

• Download and untar file system

cd ~/PROCESSOR_SDK_VISION_03_08_00_00/ti_components/os_tools/linux/targetfs/

chmod 777 ../targetfs/

wget https://software-dl.ti.com/processor-sdk-vision/esd/TDAx/vision-sdk/03_08_00_00//exports/tisdk-rootfs-image-dra7xx-evm_vsdk_3_8.tar.xz --no-check-certificate

tar xf tisdk-rootfs-image-dra7xx-evm_vsdk_3_8.tar.xz

rm tisdk-rootfs-image-dra7xx-evm_vsdk_3_8.tar.xz

• Apply the earlyboot-kernel-patches for kernel & earlyboot-u-boot-patches for u-boot

cd ~/PROCESSOR_SDK_VISION_03_08_00_00/ti_components/os_tools/linux/kernel/omap/

git am ../linux-kernel-addon/earlyboot-lateattach-patches/kernel/*.patch

cd ~/PROCESSOR_SDK_VISION_03_08_00_00/ti_components/os_tools/linux/u-boot/u-boot/

git am ../../kernel/linux-kernel-addon/earlyboot-lateattach-patches/u-boot/*.patch

Thanks
