Hello,
We require booting from USB an orin NX mounted on an A603 carrier board. We cannot boot from an SSD card since the slot will be occupied by a capture card. The user guide indicates that booting from USB is possible (quoting Flash the system to either NVMe SSD or USB Flash drive in step 6 of the “JP5.1.1 for Jetson Orin NX” tab). However, we have not been able to do so.
We have the following setup:
- Carrier board A603 SN: 102110840
- Orin NX 16Gb/8 cores SN: 900-13767-0000-000
- USB 3.0 storage
- Capture card occupying the NVMe slot
We have tried JP5.1.1, JP5.1.2 JP5.1.4 and in all cases flashing completes successfully:
> sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device sda1 \
-c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
--showlogs --network usb0 p3509-a02+p3767-0000 internal
However, rebooting afterwards fails:
- the usb flashes very briefly and then turns off
- the nvidia boot splash screen comes up
- the boot drops into the UEFI shell
- At no point is there any response to a USB keyboard, and the USB storage is not listed in the UEFI drive list
For completeness, we have successfully flashed and booted this setup from an SSD, however that option is not available to us outside of testing the board.
We suspect that the bootloader does not turn on the USB.
Could you please confirm that this setup should be able to boot from USB and what steps to take?
Thank-you
