Hello, I have a question now, I need to know which partitions are modified when upgrading the entire image containing AB partitions with nv_ota_start.sh? What steps are required to get the board into upgrade mode? In which partition is upgrade mode implemented? How do I know which partition I am upgrading during the upgrade process and which system to boot from after the upgrade?
Is there any relevant documentation that can help me answer these questions? If not, can you help me? I also need to know exactly what the OTA upgrade process looks like, because I really need to add some customization to the process right now.
