Problems flashing Orin Nano to NVME

Autonomous Machines Jetson & Embedded Systems Jetson Orin Nano

I am trying to flash a Orin Nano devkit with an NVMe. The host computer is running Ubuntu 18.04, and it is connected with a USB to the USB-C port of the board. The FC_REC pin is shorted to ground.

Sdkmanager can see the unit, but it never finishes flashing it, the first error is

ERROR: Flash Jetson Linux - flash: [ 0.0209 ] ERROR: failed to read rcm_state

The full logs are attached. (194.2 KB)

I have checked the board is correct [1]

$ lsusb
...
Bus 003 Device 030: ID 0955:7035 NVidia Corp. 
...
$ file ~/nvidia/nvidia_sdk/JetPack_5.1.3_Linux_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra/kernel/Image
/home/admin-it/nvidia/nvidia_sdk/JetPack_5.1.3_Linux_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra/kernel/Image: MS-DOS executable

The commands in [2] don’t work:

$ sudo echo 8 > /proc/sys/kernel/printk
-bash: /proc/sys/kernel/printk: Permission denied
$ sudo echo 'module usbcore +p' > /sys/kernel/debug/dynamic_debug/control
-bash: /sys/kernel/debug/dynamic_debug/control: Permission denied
$ sudo  echo 'module xhci_hcd +p' > /sys/kernel/debug/dynamic_debug/control
-bash: /sys/kernel/debug/dynamic_debug/control: Permission denied

I think the first time I tried, flashing to eMMC was an option, but now it isn’t anymore. The only choices are USB, NVMe, and SD card (although only the NVMe is actually plugged in).

Hi david.mh,

There’s no eMMC on Orin Nano devkit.

It seems there are many errors showing in your log.
Could you try to use the following command to flash your board?

$ cd <nvidia_sdk>/JetPack_5.1.3_Linux_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra
$ sudo ADDITIONAL_DTB_OVERLAY_OPT="BootOrderNvme.dtbo" ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-nano-devkit internal

Please share both flash log from host and serial console log from the device.

Here they are:

flash_3-1_0_20240516-091414.log (6.4 KB)

SSH ready
mount.nfs: Connection timed out
Flash failure
Cleaning up...

Both logs seem similar and are from host.
I want to check the serial console log output from your board.

Where are those?

These 2 logs are both from host rather than the serial console log from Jetson.

I have tried to flash again with a UART logger connected to the RX/TX headers, but there is no output at all. I am even connecting the TX pin to the oscilloscope, the trace is constant at 3.3V. What am I doing wrong?

When changing to the SD card, it boots, so the board isn’t broken.

For the Orin Nano devkit, you can refer to Jetson Nano & NX Style - Serial Debug Console - JetsonHacks to get the serial console log.
