Orin NX flash issue

[CHNtentes]

Hi. I'm using Orin NX 16GB with nvme.

When I use initrd-flash to flash my image, I need to manually select "NVIDIA RCM" in UEFI boot settings, otherwise the flash process would fail.

Is this the same issue with this?

Thanks in advance.

There's something wrong with my UART port, but I plug in a monitor and it displays system GUI, so Orin NX does boot into linux OS.

That issue should be fixed since I reworked things to insert a DTB overlay (L4TConfiguration-rcmboot.dtbo) that sets the DefaultBootPriority UEFI variable to force the RCM boot. Which branch are you using, and have you updated it recently?

Thanks for your reply. I'm using kirkstone branch cloned in February whch is indeed outdated. May I ask which commit fixed this issue?

Probably one or more of these: https://github.com/OE4T/meta-tegra/search?q=RCM+Boot&type=commits

@madisongh Hi. I updated my code and re-flashed my device. I found that there were 2 different nvme boot options in boot menu:

Is this an expected behaviour? Thanks in advance.

[madisongh]

I believe so, yes. One is for the drive, the other is for the boot partition on that drive.

[CHNtentes]

Thanks for your reply. Is it possible to remove one of those two during build time?

[CHNtentes]

NV stock L4T shows only one boot option for nvme drive.

Thanks for pointing out the discrepancy. I tracked this down to our initrd flashing scripts not properly setting the partition type code on the esp partition. Fixed with #1250.

After updating my repo, rebuilding and reflashing, I can confirm that the issue is fixed. Thanks again for your support.
