I am encountering a persistent issue with my Jetson Nano (using internal storage, not a microSD card). After attempting to install additional packages, which exceeded the available storage (only 1.1 GB free), the device now displays a white screen when connected to a monitor. I am unable to access the device via SSH, and recovery mode does not allow my host computer to detect the internal storage. Despite reflashing the device using SDK Manager, the issue persists.
Hi,
I would like to clarify some points here as there are some descriptions that are confusing.
-
“Recovery mode” is actually just a mode before you flash the board. If you want to flash any Jetson, it must enter recovery mode frist.
Thus, “recovery mode does not allow my host computer to detect the internal storage” is actually a conflicting comment to “Despite reflashing the device using SDK Manager, the issue persists.”.
If you cannot put the board into recovery mode, then you are actually not able to flash the board. Thus, above comments are confusing. It sounds more like sdkmanager didn’t do anything on your side.
If you are sure sdkmanager really flashed your board, it means sdkmanager helped you entering the recovery mode in the background and thus you might not notice. -
You can use serial console from UART interface to check the board status first.

Was this behavior happened since the beginning after flash or it happened after you install some package?
As I already shared in 2nd point, you could dump the log so that we can tell what is the next thing to check.
We are not some kind people who can directly tell you “the white screen must be from balabalah”. You need to dump the log so that we can tell you what is going on.
If you want me to guess, full disk space might lead to graphic driver not able to run but there could be something else too.
However, as you told this issue about ssh, it may not be related to disk space. ssh is dead might indicate system is not up either.
I am unable to access the device via SSH
I am writing to seek assistance with an issue I am experiencing while connecting my Jetson Nano to a monitor. When I power on the Jetson Nano and connect it to the monitor, I am encountering a persistent white screen.

What is the difficulty on your side to dump serial console log? I already told this multiple times but it seems you don’t want to do it.
Are you able to understand it or not?
understood
Just some notes or observations…
- Serial console log is unusually reliable, and simple. You do need the right cable (they are inexpensive, it uses a 3.3V level serial UART to USB cable). This access works even before Linux ever loads. Boot stages can provide information.
- Often the graphics will fail from configuration, but the system will still otherwise be fully booted. Maybe even networking will fail. However, serial console survives and can be used to actually repair some problems when there is otherwise no access (no ethernet driver is needed, no GPU driver is needed).
- If the serial port has no output, then this is a really important point in debugging.
- If you installed CAN software, and if for some reason it has a device tree edit, then this could cause boot failure. An example is if you used the device tree for a different Jetson carrier board, and not the device tree for the carrier board you are using. RPi software which alters a device tree would definitely break things. For an SD card Nano this might be in either or both of “
/boot” content and QSPI memory of the module. A serial console log would probably tell you which. Note that a new install to the SD card fixes different issues compared to flashing the QSPI memory.
