Jetpack downgrade in TX2 and connection failed

I want to downgrade Jetpack version from 4.6.4 to 4.6.3. So I used SDK Manager to flash my TX2.After the System Configuration appeared on the Jetson HDMI display,but it didn’t finish it.My TX2 showed…

At the same time,my PC (Ubuntu 18.04.6 LTS )showed “connection failed” I don’t know if this is the reason that it failed to flash TX2.


My computer is wired to the router ,and the TX2 is connected to the computer.

please help me to solve this,thank you!

At the same time,my TX2 still showed like my post’s video just now.

Then does everything work fine with 4.6.4 before you downgrade it?
Is there any reason you have to use 4.6.3 instead of 4.6.4?
Does re-flashing make any difference?

Because I want to run the model on Jetpack 4.6.3.I have posted the question,and a person said that my model can run on Jetpack 4.6.3(
Failed to build engine.py on the Jetson TX2 jetpack 4.4 - #4 by p12115803156),I have tried to run the same model on Jetpack 4.6.4,but it failed. I’m wondering if the Jetpack version is the reason why the model doesn’t run.So I want to try to downgrade the Jetpack version to 4.6.3.

hello,I can use ssh to connect my TX2.Does this help with the problem I’m having

After black screen,now,my TX2 showed…

Hi,

then is everything working fine after logging in via SSH except the EL3 exception and GUI not working?

Can you remove the quiet option in /boot/extlinux/extlinux.conf, reboot, and collect kernel log with sudo dmesg?
Please also show the content of /var/log/Xorg.0.log.

I changed the content in /boot/extlinux/extlinux.conf,maybe the reason is that I have changed the default boot option from eMMc to SD card before I flashed the TX2,and the SD card is always inserted in the machine when refreshing and booting,so it got wrong.After I restored the contents of the extlinux.conf like this


and reboot it. It can worked!And its JetPack version successfully refreshed to the version 4.6.3.

Thank you!
