Flashing Newly Built Kernel to Jetson AGX Orin causes Jetson to not boot

Robotics & Edge Computing Jetson & Embedded Systems Jetson AGX Orin

We have a Jetson AGX Orin dev kit for which we’re attempting to enable the LTC2990 configuration in the kernel. We followed the steps provided on the NVIDIA documentation for how to build and flash a kernel. After flashing the kernel, the Jetson no longer boots up. The power LED indicator turns on and so does the fan, but nothing is displayed on the monitor. Please find attached a document listing all the steps we have followed for building the kernel and flashing it to the Jetson.

We would greatly appreciate it if you could let us know what we’re doing incorrectly?

Thank you.
