I am working with the TX2 platform and had Ubuntu 16.04 on it. In order to shift from ROS Kinetic to Melodic, I upgraded the the Ubuntu version from 16.04 to 18.04 using
The system prompted me to reboot after which the system gets stuck at the bootloader (not even grub). I’ve attached the screenshots below of the screen where it gets stuck.
Screenshot after I try to access a virtual terminal (Alt+Ctrl+F3).
Note- I had uninstalled the whole ROS Kinetic distribution before upgrading ubuntu version.
Hello Kavish Shah,
Nvidia’s customized Ubuntu distributions (L4T) don’t support major upgrades using standard approach. You should use SDK manager instead.
For more information, please see these threads:
Did you use the SDK Manager to do the upgrade? Or did you use the Ubuntu mechanism? The Ubuntu mechanism will fail since it has no understanding of the custom hardware. SDK Manager 4.2 understands the hardware and is the method for flashing Ubuntu 18.04 (a.k.a., L4T R32.1 when NVIDIA-specific support is added).
Note that embedded systems do not have a BIOS or UEFI. This means all of the boot support a PC motherboard has is instead custom software on an embedded system.
We don’t provide a method to just “update ubuntu”. We only support to upgrade whole jetpack version.
If you are using 16.04, which means you are still using some rel-28.x release. And every 18.04 release are in rel-32.x.
Thanks for the reply.
I indeed used the ubuntu mechanism.
Is there a link/ document I could use to use the SDK Manager for the upgrade? Additionally, can a SD card be used to to the SDK Manager to upgrade?
If you follow the first link from my previous reply, there should be some links about SDK manager. I believe third link is what you need -
Install Jetson Software with SDK Manager :: NVIDIA SDK Manager Documentation
I don’t think that you can use SD card for that. SDK manager is a special software, which should be installed into host PC, not TX2. Host PC should be x86 based. SDK manager isn’t intended to be installed on TX2. You just use it to flash proper L4T build to your TX2 device.
Yes, what shared by
@vlad is correct. Also, there is no sdcard image for TX2 series platform.
Only Nano and NX have sdcard image. But they are not really fully reset method either.
I mean if your system crashed, changing from current sdcard image to another new sdcard image may not really reinstall everything.
Only SDKM has full reset function.
