Hello, I received a jetson Nano developer kit. I have powered it using a couple power 4amp variant especially for the Nano. I have tried multiple monitors and multiple HDMI cords but no luck. I have placed multiple SD cards in with the system on it from a previous Jetson nano. i am getting no HDMI out to my monitor. Can you please assist? Craig
Please use the serial console log to check the board status.
Also, you better checking how that developer kit looks like. There is not much real NV developer kit over the market now…
WayneWWW thank you for getting back to me so rapidly. Here is the output of the serial dump:

Looks like the bootloader software is corrupted.
There is no way to recover this by using sdcard. You must reflash the board by using another x86 host ubuntu host PC with our sdkmanager tool.
Thanks Wayne, I only have a windows PC with limited memory and likely not able to install ubuntu for windows on it. This nano was sent to me last Oct or Nov as a replacement for another defective unit - I am just getting to booting it up now. Is it possible to send this one back as well as I am not sure I want to erase lots of stuff on my laptop to make room for ubuntu and the I think the SDK manager to reflash the nano. Looking for your advice. Craig
Sorry, this situation does not match RMA situation. Your board does not have hardware defect.
Honestly, I would say if you want to develop on a Jetson device, you must prepare a ubuntu PC there.
OK Ill set it up. If I run into any probs with the reflash I will get back to you. Thanks Wayne.

Wayne one last (stupid) question. I have flashed jetpack 4.6.1 on the jetson / random SD card by using the SDK manager which I ran from an Ubuntu 18. 04 laptop. The application I have created is on jetpack 4.6 on another card of course. Will the 4.6 based application I have created run on the newly flashed Jetson Nano (which as I said was flashed with 4.6.1). The reason I ask is I put in the 4.6 based application and I seem to be having issues. Thank you. Craig
It could be related to some userspace library that might have dependencies issue.
