Grub on Orin NX

[lorenzo.ruffati]

Hi, I’m using Jetson R35.3.1 on an Orin NX module, I noticed in the boot menu there was an option to set
the boot method to Grub

Is using grub something that is actively supported or is this option a leftover from previous versions?

If the former, is there any setup guide?

Thank you for the help

My last state from @WayneWWW it is just a test for the future.

Grub boot with L4T 35.1.0

Hello, I have seen that the tegra uefi launcher is trying to boot with grub: L4TLauncher: Attempting GRUB Boot Is that something that is going to be officially supported? I have not seen any mentions about it in the documentation. I tried to boot with grub in the DP 5.0.1 but it did not work for some reason, even though the grub selection was shown. My desired layout would be: Bootloader on QSPI Grub Partition with Environment on NVME RootFS A on NVME RootFS B on NVME

I’ve been interested in it as well. Maybe something changed in the current release?

Interesting thank you, it being a test feature is definitely more encouraging than a deprecated one

Hi lorenzo.ruffati,

@lorenzo.ruffati

I noticed in the boot menu there was an option to set
the boot method to Grub

Could you help to point out where you see this option?

What’s your use case for grub?
It seems we are using UEFI for boot device selection on JP5.

In the boot menu there is an option from which I could select “Grub”, “Extlinux”, “Direct” and “Recovery” (I’m going by memory here so the specific name might change)

I imagine it is interpreted in L4TLauncher here: edk2-nvidia/L4TLauncher.c at main · NVIDIA/edk2-nvidia · GitHub

Nvidia L4T doesn’t use grub to boot OS.
You should be able to use a standard OS distribution that boots with grub if you want to.
