Hey @WayneWWW , my topic has been closed without Solution. After flashing with initrd flash to nvme the UEFI is set to boot from emmc. Can you please provide a solution? [image] Question about the boot order in UEFI (5.0.2) Jetson Xavier NX Hey @WayneWWW I have tested…

Hi, This whole thread is not related to A/B. Please wait until next release for this.

Just bumping this, as I have the same need for my product.

Hi, We have confirmed that next rel-35.x release will have a overlay dtbo which can change the boot order in it before flashing. However, this dtbo won’t work with current UEFI software. Thus, only initrd workflow 10 in rel-35.1 could change the boot order at this moment. (or only runtime UEFI m…

Hey @WayneWWW how can I change the boot order then with initrd workflow 10? When I use it to flash, the board always is set to boot from emmc.

Sorry, should be Workflow 11: Manually generate a bootable external storage device. Not workflow 10.

Hey @WayneWWW okay then I will have only the NVME formatted, as I do now. Afterwards I should use the normal flash.sh like this? ./flash.sh -c $BASEDIR/boardconfig/$PARTITION_FILE jetson-xavier-nx-devkit-qspi nvme0n1p1 So I’d flash it two times, first the nvme only, and then the QSPI with the co…

I don’t get it. I assume we get production modules from our distributor. As I understood those modules are pre-flashed with the standard image on their emmc. So the QSPI should be set to boot from emmc? When I now just flash the NVMe, would they not still boot from emmc? What you say makes only s…

I currently have no option to attach an NVMe disk to the flash PC. There is no connector. I’d have to order one. But let’s be serious. I am sure that you are misunderstanding what I am trying to achieve. What makes you think that your suggestion could work? I have a SOM with QSPI UEFI set to boot…

[image] seeky15: Why would it make any difference if I change only the content on the NVMe? I could be wrong, but the search order likely exists in eMMC (or more specifically, QSPI NOR memory). Naturally, if you boot without NVMe, then search won’t find the NVMe. However, by changing it to se…

If your board was flashed by sdkmanager/jetpack with rel-35.1 before, then running workflow 11 would be sufficient.

Running it to flash nvme drive, put it back to device and it will be able to boot from nvme.
