Boot failing while trying to setup CSI Drivers

[temilolafaith]

Currently following this guide: Raspberry Pi Camera Module 3 IMX708 Driver | Linux driver for Jetson | RidgeRun RidgeRun/RPI Camera Module 3 (IMX708) open access driver for NVIDIA Jetson Orin Nano and Jetson Nano - Jetson & Embedded Systems / Jetson Nano - NVIDIA Developer Forums

After rebooting, I got this via serial console

I made backups of the extlinux.conf file as well as backups of the Image. How do I access them to restore the previous boot config/image? I tried changing this using Boot Manager but it defaults to Direct Boot

hello temilolafaith,

may I know the content of your extlinux.conf, for instance, did you create another LABEL for selection?
besides, you may see-also developer guide, Device-tree overlay section for camera driver development.

[temilolafaith]

No, I did not create another LABEL. In hindsight, I should have used the backup image for a backup label. Here’s the content:

TIMEOUT 30
DEFAULT Develop

MENU TITLE L4T boot options

LABEL primary
MENU LABEL primary kernel
LINUX /boot/Image
FDT /boot/dtb/kernel_tegra234-p3767-0003-p3768-0000-a0.dtb

hello temilolafaith,

this is incorrect, you did not have LABEL Develop in the configuration file.
please try duplicate the content of LABEL primary, and changing the entry you’re going to load via file system for development.

How do I edit the configuration file? I tried following How to use /boot/extlinux/extlinux.conf after jetpack 5.0 - #5 by lr75021 but when I go to Boot Manager, there is no eMMC option, but an SD one as shown in the screenshot in my original post and when I select that, it defaults to Direct Boot, not giving me an option to edit the configuration file

please refer to developer guide, Set the Configurations in the UEFI Menu.
