I just purchased a new TX1 devkit while my other one is in RMA for that old WiFi bug and I’m having some trouble with the new one. The TX1 shows up in recovery mode over USB and I’m able to use Jetpack to flash the latest L4T 24.1 on it. I can reboot and the GUI works fine. WiFi works and everything. As soon as I shut down, however, it no longer boots. There’s absolutely nothing on the serial terminal either after the shut down. The TX1 does show up in recovery mode on USB again though. And I can flash it again with Jetpack, but I get the same behavior. Reboot works after flashing, but once it’s shut down it can’t boot anymore and comes up in recovery mode.
I’m using a dedicated Ubuntu 14.04 LTS host machine, not a VM.
There were some Jetsons which required a quick double-tap of the power button. Can you try two (or several) quick power button presses to see if this is the case? The fact that it reaches recovery mode means it basically works, and the tail of the flash said it succeeded (this doesn’t mean the file system put on it is good, but likely it is).
