Jetson TK1 not booting (but flashing)

Hello

Jetson TK1 works fine but once it just stop reacting (hangs out). We reboot it and after this Jetson powerd up for 3-4 seconds (fan works, green led) and than stops. No output on HDMI.

We put it in recovery mode, successfully flashed (without any error or warning messages) and after rebooting behavior the same - fan works 3-4 second and than stops. We makes reflash 2-3 times more with no luck.

Any suggestions how to repaire it?

Would you be able to get a serial console boot log to see where it stops? You’d need something like a USB serial UART with a DB-9/RS-232 connector with settings 115200 8N1.

A log of the flash would possibly also help, e.g., something like:

sudo ./flash.sh -S 14580MiB jetson-tk1 mmcblk0p1 2>&1 | gawk '{gsub("[0-9][0-9]+[/][0-9[0-9]+ bytes sent..",".");print}' | tee log_flash.txt

The “gawk” in the flash just cuts out excessive progress bar text.

If you hover your mouse over the quote icon in the upper right of one of your existing posts you’ll see other icons show up. The paper clip icon would allow attaching logs. Also, mention which release you are using.
