I have a custom Orin Nano board, and after flashing r36.3, I checked the system and found that the device name is Orin NX. Why is this happening, and what are the implications?
root@b1 /h/orca# cat /proc/device-tree/model
NVIDIA Jetson Orin NX Engineering Reference Developer Kit⏎
Hi zjy523213189zjy,
Is the custom carrier board designed by you?
Please share the result of the following command on your board.
$ cat /etc/nv_tegra_release
$ cat /etc/nv_boot_control.conf
Yes
root@b1 /h/orca# cat /etc/nv_boot_control.conf

It seems you are using Jetson Orin Nano 4GB (P3767-0004), which is correct from command you shared.
It seems captured from device tree model = NVIDIA Jetson Orin NX Engineering Reference Developer Kit"
It seems only SKU 5 would show NVIDIA Orin Nano developer Kit since SKU5 come with Orin Nano developer kit.
Please also share the full device tree for further check.
tegra234-p3768-0000+p3767-0004-nv.dts.gz (36.7 KB)
I get this dts file by command: dtc -I dtb -O dts kernel/dtb/tegra234-p3768-0000+p3767-0004-nv.dtb > tegra234-p3768-0000+p3767-0004-nv.dts
model = "NVIDIA Jetson Orin NX Engineering Reference Developer Kit";
Yes, it shows the above in your device tree.
Orin NX/Nano are from similar series so that it shows Orin NX Engineering Reference Developer Kit.
You can customize it as you want.
I get it. Thanks.
Another question, why free -h shows only 3.5GB mem total, and 400M used, but there are no running application.
that means only about 3G memory are available?
Please always file a new topic is question is not related to original topic.
Will next jetpack release fix the device name?
In my opinion, the model in the device tree of P3767-0003 and P3767-0004 should both be Jetson Orin Nano.
No, our Orin Nano devkit come with Orin Nano 8G SD module(SKU 5) so that only it shows NVIDIA Orin Nano developer Kit.
For other SKUs, it would show NVIDIA Jetson Orin NX Engineering Reference Developer Kit since they are from similar design as Orin NX.
If you want it showing NVIDIA Jetson Orin Nano Engineering Reference Developer Kit or something else, you can simply customize it in device tree as you want.
