How to reuse the same image with different orin super module?

In jetpack 5 and Jetpack6.1,I change the DTB file metioned in extlinux.conf,so that same image can be used with different orin module,I don’t need to make 4 same image with different module,but this method seems didn’t work with super in Jetpack6.2 cause the extlinux.conf seems a lot different.So how can I reuse the same image with different orin super module?Or can I modify the extlinux.conf to boot with searching the DTB file?

Hi MaxineZ,

Are you using the devkit or custom board for Orin NX?

What do you mean about “different orin super module”?
Please share the result of cat /etc/nv_boot_control.conf on these modules.

You can just specify FDT entry in extlinux.conf for the DTB loaded in kernel.

I use custom board with orin,both orin nano and orin nx,so there are 4 modules in orin.

And here,I change the dtb file highlight in this picture,then my image can boot with all the orin module.But now I found no FDT in new orin super,can I just add FDT entry in extlinux.conf?Will that affect the super performance?

Yes, you can just manually add FDT entry back to specify the DTB in use.
e.g.

FDT /boot/dtb/kernel_xxxx-super.dtb

Please refer to DTB Support to know how DTB loading works.

No, it should be fine if you’ve loaded the correct DTB with ending of -super.

Thanks! I’ve already solve this problem by adding FDT entry with correct dtb file in extlinux.conf
