Greetings,
I am working Jetson AGX Xavier controller with two partitions. After the OTA update is successful I manually power off the unit and turn it on after 1 minute. With some of our new boards we are noticing the bootloader is not getting enough time update the bootloader after the OTA update is performed, and eventually failing to automatically switch to the updated boot slot.
Can you please help us understand the following:
- expected boot sequence after power on.
- are there any firmware resets that occur during bootloader update after OTA.
- If these resets are caused by power controller on the board, can you help us understand the hardware pin that controls the reset or the configuration that controls the reset on boot up.
I am attaching the serial logs from when the bootloader update failed.
