Hi,
Jetson orin NX/Nano with Jetpack r36.3.
Can I customize a shell command in UEFI?
My goal is to format a partition of an SSD, which is done in recovery. Currently, Linux commands under Ubuntu can trigger this action and it has been verified successfully. I need to add this feature to the shell or boot menu in UEFI as well.

Hi weiyf1,

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

It seems you could do this in linux after boot up.
Why you have the requirement to do it in UEFI shell?

Have you tried to build the custom UEFI binary?

— Good idea, it will be work.

Have you tried to build the custom UEFI binary?
—I have updated the logo and added shell commands in UEFI, but it is difficult to format or process BLK block devices in UEFI.

Yes, it may be more difficult to do them in UEFI since you might need to write a custom driver for your use case.
