neither of them works. I also tried the SDK manager instalation but there only is clean jetpack. Flash from host machine works (ubuntu18.04), but this jetpack doesn’t have modules and system cofiguration to work properly on jetracer robot:
I guess it is “jetson” “jetson”, but i remeber that i didn’t get the hdmi output. I can just input it “blindely” with serial debug console. I will let you know if it worked.
Hello, I’m a colleague of Voznyak. I wrote to waveshare in the meantime, but their help basically boiled down to ‘try to flash the sd card once again’, ehh…
So to give more platform data:
Platform: JetRacer AI Kit
Hardware: Waveshare JETSON-NANO-DEV-KIT, Model P3448 180-13448-DAA-B01 (the one with eMMC) on JETSON-IO-BASE-A board and JetRacer Expansion Board.
I first followed this: waveshare com/wiki/JETSON-NANO-DEV-KIT#Overview
to flash the image to the eMMC chip using the SDK manager. I also modified the device tree and some files, such as in the sections “Boot TF Card > Method 2: Another Image on the SD card” and “Hardware Control”. As a result, the device boots and sees the connected SD card in the baseboard slot. What is important wifi works. However, this image lacks the files to connect and use the JetRacer expansion card.
So I followed this tutorial: waveshare com/wiki/JetRacer_AI_Kit#Jetson_Official_Resources
and, following the instructions, I saved the Jetpack4.5 image to the SD card. I also resized the application partition to full memory size. When I try to boot from it, on a connected display appears the nvidia screen, followed by a bunch of log lines, then display blinks a dozen of times and then goes back to logs. GUI does not start. Here is log of booting: reboot_log.txt (213.2 KB) . Using startx I got this error: startx_error.txt (5.7 KB) , and full log of the error: Xorg_full_log.txt (21.7 KB)
The variable $DISPLAY was empty. When I assigned some number (:0, :1, etc), it did not helped.
I have managed to run GUI on ligthdm, but only one time. After that it got stuck in login loop each time (after loging-in immiedietly was going back to login menu).
On the other side, JupyterLab server works fine and I can move the servo and wheels… Unfortunatly on this image also wifi is not working (ifconfig does not show wlan0): ifconfig.txt (5.5 KB)
