I'm seeing more and more often our custom board entering BOOTLOADER SHELL MODE

[unphased]

custom carrier board with the optional reboot timing circuit as detailed by my colleague in:

Reboot stops working on Jetpack 4.6.2 after update from Jetpack 4.6.1

Hello, This alteration to the device tree allowed us to produce a working reboot on a custom carrier board with the optional reboot timing circuit. After doing an apt update and apt upgrade, the reboot no longer functions. We can go back to 4.6.1 but we want to make sure we’re keeping up with updates. Is there something we need to change to get it to work again? Do we need to revert to the original device tree?
