Hello experts, I can flash my custom Orin NX board if I use the sdkmanager in GUI mode. My board is recognized as ‘Jetson Orin NX modules’ either with a Jetson Orin NX 8GB or Jetson Orin NX 16GB, depending on the SOC I plug on it. I can flash it perfectly with ‘Jetpack 5.1.2’ and ‘NVMe’ as ‘Sto…

OK Thank you, but … previously it was possible to create a file named ‘myboard.conf’ and then run something like sudo ./flash.sh myboard nvme0n1p1 Is that deprecated, or not supported anymore ?

flash.sh only supports eMMC/SD card, but not NVMe drive.

OK Thank you How can I add the pre-config (user and password) options to the l4t_initrd_flash.sh command line ?

OK that works ! I have found how to specify the board specific PINMUX_CONFIG, PMC_CONFIG and DTB_FILE, but how can I specify the kernel that must be run after the installation ?

[image] phdm: but how can I specify the kernel that must be run after the installation ? You mean you want to replace the kernel image at runtime?

Yes, I want to run a self-compiled kernel tailored for the board, with additional drivers. This kernel is tested and runs perfectly if installed instead of the default kernel afterwards, but I would like to install it at the flashing time.

Replace Linux_for_Tegra/boot/Image with your own kernel.

Will Linux_for_Tegra/boot/Image be run during the flashing process ? If yes, are there any driver or config options that must be provided by that kernel ?
