I downloaded Jetpack 4.4 DP today. Installed on ubuntu 18.04 host system, downloaded all installers. Flashed the device, everything goes through ok. Then after flashing i reset the Xavier NX module (on an auvidea JN30 carrier board, mfr assures me this should work up to 15W). But unfortunately after reset, there is no signal on HDMI output. Power lights are on and MCU light is flashing 1 sec on 1 sec off.
I repeated the whole process with SDK Manager again and the same thing happened, no HDMI output.
I tried running the flash.sh script from the command line to monitor for errors and everything seems to go through ok, this is my command:
sudo ./flash.sh jetson-xavier-nx-devkit-emmc mmcblk0p1
on execution completion I get :
*** the target t186ref has been flashed successfully ***
Reset the board to boot from internal eMMC
Everything seems to through ok with the flashing process. Just no HDMI on reset…
