VAR-SOM-AM62 - Debian Customize from source code
Introduction
This guide demonstrates how to patch and rebuild the VAR-SOM-AM62 U-Boot images.
To learn how to build the U-Boot images outside of Debian, see: Build U-Boot from source code
Add your patches on top of the Variscite source code
Fetch the U-Boot source:
$ mkdir -p ~/am62_debian_uboot && cd ~/am62_debian_uboot $ git clone https://github.com/varigit/ti-u-boot -b ti-u-boot-2023.04_09.02.01.10_var01 $ cd ti-u-boot $ git clean -fdx
Next, make the desired changes to the U-Boot source code. After changing the source code, create a diff file:
$ vim board/variscite/am62x_var_som/am62x_var_som.c $ vim include/configs/am62x_var_som.h
edit and save
$ git diff > ~/am62_debian_uboot/ti-u-boot/uboot.diff
Refer to the instructions on how to download the Debian source code and apply the U-Boot patch during the Debian image build process. After cloning the Debian source code, it will be located in the ~/debian_am62x_var_som/ti-bdebstrap/".
Create the directory ~/debian_am62x_var_som/ti-bdebstrap/patches/ti-u-boot and copy the uboot.diff patch.
$ mkdir -p ~/debian_am62x_var_som/ti-bdebstrap/patches/ti-u-boot $ cp ~/am62_debian_uboot/ti-u-boot/uboot.diff ~/debian_am62x_var_som/ti-bdebstrap/patches/ti-u-boot
Refer to Build and flash the Debian image with uboot changes.
Use your remote repository on GitHub
Create a GitHub account and upload your proprietary U-Boot to a new repository: You can fork our repository to your account by visiting the following link and clicking on "Fork" at the top right of the screen: https://github.com/varigit/ti-u-boot/tree/ti-u-boot-2023.04_09.02.01.10_var01
Alternatively, you can clone the repository to your local machine, and push it later to your account.
Refer to How to Download Debian Source Code. After downloading the source, open the file ~/debian_am62x_var_som/ti-bdebstrap/configs/bsp_sources.toml and locate the tag 09.02.01.10_var01.

Finally refer to Build the Debian image with updated u-boot repository.
