I am working on Jetson Orin NX based custom board.

I run boot tests with OrinNX. In most cases, it boots up successfully.
In rare cases, OrinNX fail with the following error.

I> Task: Audit firewall settings (0x50023bd0)
I> Task: Bootchain failure check (0x50002434)
I> Current Boot-Chain Slot: 0
I> BR-BCT Boot-Chain is 0, and status is 1. Set UPDATE_BRBCT bit to 0
I> MB2 finished

I Checked Orin NX 16GB with orin nano developer kit.
The same error occurred.
It occurred after rebooting about 600 times.
Only power and UART serial are connected.
