Recently purchased a few Jetson Nano Dev kits. 2 of them were not displaying the Nvidia screen on powering up.
The modules from them were put on other Nano carrier boards, Nvidia screen doesn’t show up.
Other working modules were tested on these new carrier boards, they boot up as they are supposed to, displaying Nvidia screen on powering up.
Tried with and without SD cards in them.
In any case, the 2 new modules aren’t displaying Nvidia screen in any carrier board, but the 2 new carrier boards are able to boot up other Nano modules.
These dev kits are brand new, off the box. Our initial analysis is that the modules are defective. Appreciate any help or insight regarding this.
Tried accessing Jetson via the serial debug console. You can refer the log file below:
