I would like to share the process of how I managed to flash a Jetson TX2 NX Module using the Turing Pi 2 cluster board. The process described in the attachment failed when the module was located in slot 1, but it worked perfect in Slot 2.

I ran into this problem while running through this script from Ubuntu 23.04 and had to create a

python

symlink to python2.7 to get around it. https://forums.developer.nvidia.com/t/flashing-xavier-nx-emmc/187379/5

Hi @cyliew, love your process description! Tiny addition though, to your Mark Down file. Prerequisite is to have Qemu installed on the host machine where you prepare the System Image. simple sudo apt-get install qemu-user-static solves it!

nvme root was working after running through the script. I did this all from node 1 which helped since I could watch the boot over HDMI. The next thing I tried doing is upgrading Ubuntu to the next LTS release (20.04). This seems to have reverted the nvme root boot. Despite updates to extlinux.cfg and fstab, it continues to boot the old kernel and mount the emmc root. The next thing that I need to understand is how to make these kinds of changes persisted from within the OS (if possible). The nv_* tools seem like they'll be used for this, but I haven't figured out how yet.

I would recommend to stay with the official supported 18.04 kernel. I also ran into the same issue where the kernel log was flooded with a lot of errors: ===== Apr 17 13:18:54 jetson-tx2-01 kernel: [ 8.752396] pcieport 0000:00:03.0: can't find device of ID0060 Apr 17 13:18:54 jetson-tx2-01 kernel: [ 8.752398] pcieport 0000:00:03.0: AER: Multiple Corrected error received: id=0060 Apr 17 13:18:54 jetson-tx2-01 kernel: [ 8.752404] pcieport 0000:00:03.0: can't find device of ID0060 Apr 17 13:18:54 jetson-tx2-01 kernel: [ 8.752406] pcieport 0000:00:03.0: AER: Multiple Corrected error received: id=0060 Apr 17 13:18:54 jetson-tx2-01 kernel: [ 8.752412] pcieport 0000:00:03.0: can't find device of ID0060 Apr 17 13:18:54 jetson-tx2-01 kernel: [ 8.752414] pcieport 0000:00:03.0: AER: Multiple Corrected error received: id=0060 ===== With once a while these errors popping up: ===== Apr 17 13:18:54 jetson-tx2-01 kernel: [ 8.783282] pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=0018(Receiver ID) Apr 17 13:18:54 jetson-tx2-01 kernel: [ 8.793451] pcieport 0000:00:03.0: device [10de:10e6] error status/mask=00000001/00002000 Apr 17 13:18:54 jetson-tx2-01 kernel: [ 8.801796] pcieport 0000:00:03.0: [ 0] Receiver Error (First) ===== I described here how I got rid off these errors: https://discord.com/channels/754950670175436841/1096365412029046874/1097538957161537556

Happy to announce that I had a successful flash using some old hardware, installing Ubuntu 18.04.6 LTS (upgrading from 12.04 LTS btw). One of the TX2 NX using a 50 cm and one using a 100cm USB A male to USB A male cable. Both on slot 2

would this method work on any of the jetson bo1?

I'm using Ubuntu 18.04 on vmware. I get:  /Linux_for_Tegra/bootloader/tegrasign_v3_internal.py", line 453, in do_aes_cmac [ 1.5150 ] write_file(raw_file, result_name.encode("utf-8")) [ 1.5150 ] UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 36: ordinal not in range(128) when i run: /Linux_for_Tegra$ sudo ./flash.sh jetson-xavier-nx-devkit-tx2-nx mmcblk0p1 There's some issue with locale and python2.7 encode/decode. I was wondering if anyone ran into this. I did run sudo apt update. do we have to do anything special after installing ubuntu?

Flash completed successfully, I see DHCP lease for host name specified in ‘l4t_create_default_user’, but I can’t ssh in, getting timeout …

Hello Ax did you follow the instructions in this forum? Or sometime else.

I followed instructions from this thread, I think only differences that I did it from VirtualBox and Jetpack 4.6.4 instead of 4.6.3

Same for me, following the instructions by Cyview above. But using physical hardware to do a fresh install of Ubuntu instead of VirtualBox

Anyone else get stuck at "[ 8.2664 ] Sending bct_mb1"? Error: Return value 3 Command tegrarcm_v2 --download bct_bootrom br_bct_BR.bct --download bct_mb1 mb1_bct_MB1_sigheader.bct.encrypt Failed flashing t186ref.

@pradg73 It was a unicode issue, indeed. The short answer is use Python3 not Python2.7 I put together these instructions and I figured out the the problems flashing when I encountered the same errors. Consider it a troubleshooting addendum to @User instructions. https://cdn.discordapp.com/attachments/1102175059973509120/1167745857974702131/jetson-tx2-nx-module-flashing-unicode-error.md?ex=654f3f14&is=653cca14&hm=2aae28247137b81f6d16236ef54b4b7e94f7f1fff288fd16db302766e7c02075&

Python 2.7 is long dead. Leave it 😛

I had ultimately managed to flash the tx2 nx but I'm unable to ssh into it. The session simply closes connection. I tried the USB mpcie adapter but the keyboard and mouse don't respond. Gave up and moved on.

SSH would not work if you did not use unattended installation (SSH will only activate when you finish setup using keyboard/mouse/screen)

I tried to ssh into mine, while my board and Jetson did pick up DHCP addresses. I had troubles last night ssh'ing in, even though I did the unattended setup. I wonder what USB mpcie adapter I should buy?

trouble as in? Were you able to ssh in or not?

I couldn't SSH into the device nor could I ping. No route to host, which is strange because it picked up an IP. Last night I moved the Jetson TX2 NX to Slot 1, and I saw the NVIDIA splash screen and Ubuntu log in prompt via HDMI

Good luck... I came to the same point but for me the keyboard mouse didn't work. I got the mpice mentioned in the docs somewhere. Maybe the USB cable wasn't, right.. I don't know. I spent too much time on it and it didn't work.

Update, I installed the mpcie, but I couldn't get the USB Mpcie to work, I'm going to try and reseat the card tomorrow. However something strange happened and I was able to SSH in today! I am super happy. I installed XRDP and XFCE4. I had some extra steps that I will document on what I had to do to copy the rootfs over to my Nvme and then manually update my /etc/fstab afterwards to boot the OS from my NVMe SSD.

Wow! Glad it worked for you. I have the exact same hardware.. didn't work nor could I ssh in. Happy for you. Alas, some of us are not so lucky...

I have tried various iterations of the SDK manager (4.6.4, 4.6.3, 4.6.2). I also followed the instructions provided at the top of the topic.... all roads lead me to the flashing itself hanging on this message:

tegracrm_v2 --isapplet

I've tried hooking up the uart but I'm not sure if I'm doing something wrong or what but I get a bunch of messages like the baud rate is wrong though I've followed what I can tell is right for the tx2 nx (115200 8N1; minicom set for software flow control). I tried 115200 and different baud rates in gtkterm and have been able to view the BMC UART just fine-- but never the tx2 nx. I upgraded my BMC firmware to the most recent RC from just a few moments ago and am having the same issue. Has anyone been successful with UART? or have recommendations of what to try to flash?

Hey Aztzak yes I've successfully connected to BMC UART with a Jetson TX2 NX and the TPI 2 Board. I purchased and used this cable https://www.amazon.com/dp/B00DJUHGHI?psc=1&ref=ppx_yo2ov_dt_b_product_details and used the CP210x Drivers

Thanks for replying, were you able to use the UART for the Jetson? I was able to work with the BMC OK just not the Jetson.

Oh for the Jetson yes I think so, I bought a USB A to A cable Monoprice USB 2.0 Type-A Male to Type-A Male Cable - Gold Plated, For Data Transfer Hard Drive Enclosures, Printers, Modems, Cameras and More, 28/24AWG, 6 Feet, Black https://a.co/d/eyWVbET

Yeah, both fail for me :/

Hey folks, did anyone here ever manage to interact with their TX2 over UART or mPCIe USB adapter? I borked mine a while back (maybe dodgy fstab edit, can't remember) and now it only boots into emergency mode -- not recovery mode. All it wants me to do is press enter to go to maintenance mode but nothing I've tried lets me send any kind of keypress to it.

I could not get USB UART to work, same issue you’re describing where it seemed like I had the wrong baud rate ( so I tried every common combination )… I eventually gave up after I was able to flash over usb with a good quality cable.

Yeah it feels like there's something about TX2s and Turing Pis that doesn't mesh well, once it's flashed you're all good but trying to interact directly is a nightmare
