How to Build UEFI Bootloader for JetPack 5.1.3 (R35.5.0)

Issue Overview

Users are experiencing difficulties in upgrading their systems from JetPack 5.1.1 to JetPack 5.1.3, specifically regarding the integration of UEFI bootloader changes made in the previous version (R35.3.1). The main symptoms include:

• Inability to locate branches related to R35.x for UEFI bootloader updates.
• Confusion over how to successfully build the UEFI bootloader for the new JetPack version.

This issue typically arises during the upgrade process when users attempt to implement custom UEFI changes from JetPack 5.1.1 into the newer version (5.1.3). The hardware specifications are not explicitly mentioned, but it is implied that users are working with Nvidia Jetson Orin Nano Dev boards, which require specific configurations for bootloader compatibility.

The frequency of this issue appears to be moderate, as it was raised by at least one user and acknowledged by another who confirmed a successful resolution using provided commands.

The impact on user experience is significant, as failure to upgrade the bootloader can prevent users from utilizing new features or improvements offered in JetPack 5.1.3, thereby limiting system functionality.

Possible Causes

Several potential causes may lead to the issues users face when building the UEFI bootloader:

• Hardware Incompatibilities: Users may not have compatible hardware that supports the latest UEFI changes.

• Software Bugs or Conflicts: There may be bugs in the JetPack software that prevent successful integration of UEFI changes.

• Configuration Errors: Incorrect settings or configurations from previous versions may lead to problems during the upgrade process.

• Driver Issues: Outdated or incompatible drivers could hinder the proper functioning of UEFI on the new JetPack version.

• User Errors or Misconfigurations: Users may not follow the correct procedures for building or upgrading the bootloader.

Each of these causes can contribute to difficulties in successfully building and implementing the UEFI bootloader on JetPack 5.1.3.
