Hello everyone, I’m having a real hard time trying to make this whole thing work, but I’ll explain myself.
I have to use this neural network with the help of the Jetson TX2, which is very convenient as the CNN offers the possibility of GPU acceleration via CUDA.
However, I’m having a lot of trouble trying to flash my Jetson; I’ve downloaded the proper version of Jetpack (3.3 if I remember it correctly) and it installs successfully on my host PC with Ubuntu, but it’s been impossible for me to get the Jetson into recovery mode.
I’ve tried lots of differents configurations so as to determine where the failure is, and I’ve already discarded malfunctioning of both power supply (right now I’m using the typical “configurable” power supply provided in most laboratories, like this one) and micro-B USB cables, as I’ve tried with a bunch of different, well working ones and it still didn’t work.
So this leaves the failure either to the dev board I’m using or the Jetson itself, provided that the USB ports on my PC aren’t trolling me. The board I’m talking about is the Orbitty Carrier, whose manual is here. In the “Force Recovery Mode” section, which seems to be a copy/paste of the instructions in the Jetson Developer Kit User Guide, I’ve followed the steps lots of times in different ways and still accomplished nothing.
I’ve tried to press power on the board while holding recovery, press reset after pressing power while holding recovery, press power during 5 seconds (so that the “hard power off” was triggered) then release it while holding recovery (all of this with power supply on beforehand) and connect the power supply while holding recovery, everything to be a complete failure. I even tried to do it with the expansion pins that the board provides, as they extend the three POWER/RESET/RECOVERY buttons, but nothing again.
So right now, I’m running out of ideas and I’d like to ask you for your help, because I’m starting to think it might be a problem with the Jetson, but I can’t think of any way to check if I’m right or not. It could also be a problem with the board and its connections to the buttons with the Jetson, but same as before, I’m not able to determine it.
What are your thoughts? Any other tests that can be run to determine the failure? Should I consider a RMA? And last but not least, do you know if it’s possible to use the SD slot offered by the Orbitty Carrier to boot the Jetson? (I don’t think so, but any ideas are welcome)
Thank you very much for your help and time
