Hard reset

I had attempted to install and set up the device multiple times, but the installation process failed each time and I was unable to complete the configuration. After that, I modified the BIOS settings, and following that change, the system no longer boots. Before applying the changes, the BIOS displayed that the configuration would be altered, but I proceeded — the device powered on at the time but has not booted successfully since.

Currently, the device does not boot, the screen does not turn on, and I cannot access the system in any way.

I would like to hard reset or enter Force Recovery mode in order to reflash the device and install Linux.

Could anyone please advise:

  • How to perform a full hardware/factory reset on this device?

  • Is there a specific procedure to reflash the device when it does not boot at all?

Any guidance would be greatly appreciated. Thank you.

Hi,

Please prepare a native ubuntu and install sdk manager to full flash the device.

Thanks

Hi David,

Thanks for the information. I’ll install it as you mentioned. However, there is a problem - when I boot the device, it shows a black screen (not opening). How can I hard reset it (with a pin, etc.)? I have tried different pin combinations, but it is not working.

Thanks.

If you want specific details, then you’d need to monitor the serial console during boot (and keep a log of it for posting). However, a black screen does not necessarily mean anything more than video configuration issues. Is your monitor a somewhat “standard” HDMI or DisplayPort? If it is something without that, then it might be a lack of automatic configuration information missing from the monitor. If the configuration is available, but the device is using some sort of odd settings (e.g., some tiny monitor for portable use), then it might just be failing to accept those settings.

Serial console is very simple and useful and tends to provide service even when video and other parts of the system have crashed and burned. If you go here:

…then you will see information about serial console. Connector J14 is under the module itself, and is not part of the 40-pin header. There is actually a difficult-to-see solder mask marking pins, bit it might require a magnifying glass to read it. The GND pin is ground, and there will be a TXD and RXD for the serial console UART (it uses a 3.3V logic level, setting is 115200 8N1). A serial UART cable with its TX to the RXD, and the cable’s RX to the Jetson’s TXD (and ground to GND) at those settings will make life much easier for anyone working on one of these.

Some of the other Jetson formats have an actual micro-OTG USB port which works if you plug in a USB charger cable to that (though charger cables tend to have dubious data quality wires), and the type-A connector to the host PC. None of them will use the 40-pin header for serial console.
