Hello,

To customize the U-Boot for your Verdin AM62 module and remove USB, Ethernet, and MMC1 boot options, you will need to modify the U-Boot configuration files rather than the device tree files. U-Boot boot options are typically controlled through configuration settings in the U-Boot source code.

Here are the steps you can follow:

  1. Access U-Boot Configuration: Navigate to your U-Boot source directory, which you mentioned as u-boot-toradex-ti.

  2. Modify Configuration Files: Look for the configuration header files, typically named include/configs/<board_name>.h. This file contains macros that define the boot options.

  3. Disable Boot Options:

    • USB Boot: Locate and comment out or remove any macros related to USB boot, such as CONFIG_CMD_USB or CONFIG_USB_STORAGE.
    • Ethernet Boot: Similarly, find and disable macros like CONFIG_CMD_NET or CONFIG_NET.
    • MMC1 Boot: Look for CONFIG_MMC or CONFIG_CMD_MMC and adjust accordingly.

  4. Rebuild U-Boot: After making these changes, rebuild U-Boot to apply the new configuration. Use the appropriate make commands for your setup, ensuring you target both the A53 and R5 processors if required.

  5. Deploy the New U-Boot: Once built, deploy the new U-Boot binary to your module.

Device trees are primarily used for hardware configuration and peripheral setup, not for boot option management in U-Boot. Therefore, your focus should be on the U-Boot configuration files for this task.

By following these steps, you should be able to customize the U-Boot to meet your specific boot requirements for the Verdin AM62 module.
