I was trying to set up a Jetson Orin Nano (Developer Kit) by flashing it with a Micro SD card using the instructions provided here (Jetson Orin Nano Developer Kit Getting Started | NVIDIA Developer). I used Balena Etcher to flash the SD card. However, after flashing the Micro SD card, inserting it into the Jetson and connecting it to an external monitor, the monitor showed the NVIDIA logo for about 15 seconds before the screen shuts off and shows “No Signal Found from Source”.
To investigate that, I connected the Jetson to a host computer using a tty cable and used a serial debugger to check what the error message was. Here is what showed up -
"[ 8.025275] tegra186-cam-rtcpu bc00000.rtcpu: RTCPU trace: IOVM setup error:0 [ 8.025285] tegra186-cam-rtcpu bc00000.rtcpu: trace boot sync failed: -5
** 906 printk messages dropped **
[ 8.040511] tegra-nvenc 154c0000.nvenc: _opp_is_duplicate: duplicate OPPs de1 ** 164 printk messages dropped ** "
How do we fix this problem? What does this error message mean?
