[参考译文] AM625：在 AM62 Android SDK09.02.00上执行 DFU 闪存 EMMC 之前、需要将哪些内核文件从 ti-kernel-AOSP 和 ti-bootloader-AOSP 移至 ti-AOSP-14？

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1382653/am625-which-kernel-files-need-to-be-moved-from-ti-kernel-aosp-and-ti-bootloader-aosp-to-ti-aosp-14-before-performing-dfu-flash-emmc-on-am62-android-sdk09-02-00

工具与软件：

CPU：AM6254ATCGGLW

交叉编译器： PROCESSOR-SDK-ANDROID - AM62X/09.02.00

构建代码： Overview_Building_ 201_SDK

DFU 闪存： Overview_Flashing .html

尊敬的  TI 团队：

请帮助我解决在构建 SDK 和 DFU 闪存 EMMC 时遇到的问题。

下载并构建默认 SDK 代码 cmd：

export YOUR_PATH=$PWD
export PATH=/opt/arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu/bin/:$PATH
export PATH=/opt/arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf/bin/:$PATH

编辑.dts 并构建内核 cmd：

export YOUR_PATH=$PWD
export PATH=/opt/arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu/bin/:$PATH
export PATH=/opt/arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf/bin/:$PATH

#edit ${YOUR_PATH}/ti-kernel-aosp/common/arch/arm64/boot/dts/ti/k3-am625-sk.dts
#edit ${YOUR_PATH}/ti-kernel-aosp/common/arch/arm64/boot/dts/ti/k3-am62x-sk-common.dtsi

echo "start> 3:Build Instructions-Kernel"
##Build Instructions-Kernel
###Building everything from scratch
if [ -d "${YOUR_PATH}/ti-kernel-aosp" ]; then
  cd ${YOUR_PATH}/ti-kernel-aosp/
  export DIST_DIR=${YOUR_PATH}/ti-aosp-14/device/ti/am62x-kernel/kernel/6.1
  tools/bazel run //common:ti_dist -- --dist_dir=$DIST_DIR
fi

闪存 EMMC SOP：

01.(build code PC)cd ${YOUR_PATH}/ti-aosp-14/out/target/product/am62x
02.(AM62)set bootmode to DFU mode
03.(AM62)power on
04.(build code PC)snagrecover -s am625 -f ./am62x-sk-evm.yaml
05.(AM62)interrupt U-Boot to go in console
06.(AM62)=> env default -f -a; saveenv;
07.(AM62)=> fastboot 0
08.(build code PC)sudo ./flashall.sh --board am62x-sk
09.(AM62)power down
10.(AM62)set bootmode to EMMC mode
11.(AM62)power on

构建内核后、哪个文件需要 从 ti-kernel-AOSP 和 ti-bootloader-AOSP 的 CP 到$｛your_path｝/ti-aosp-14/out/target/product/am62x 才能运行 flashall.sh。

谢谢！
