Note: Jetpack/L4T upgrade using debian package management tool is now fixed and reenabled.

We had temporarily disabled the feature of upgrading JetPack or L4T using debian package management tool due to an issue we found in one of our debian packages causing the device to not boot properly. We have fixed this issue now and have reenabled this feature. We are sorry for the inconvenience caused.

I also can no longer access it.

Hi,

If anyone get system stuck after running OTA update, please refer to this thread.

@WayneWWW I see that starting with 32.4.3 the BSP archive and BSP sources became restricted downloads - member account needed.

Is this intended, like for some licensing changes or similar? Thank you

Hi,

I am not sure what do you mean. On our dlc, we always require you to login before download the source code.

Hi @WayneWWW, for previous L4T releases like 32.4.2 it is possible to wget the BSP Archive in the L4T download page.
Starting with 32.4.3 it is necessary to be authenticated to download the BSP archive:

L4T 32.4.2:

wget https://developer.nvidia.com/embedded/L4T/r32_Release_v4.2/t186ref_release_aarch64/Tegra186_Linux_R32.4.2_aarch64.tbz2

Hi,

Sorry that I don’t know there was such change before. It is more related to the web backend here so I cannot answer.

This should be fixed now. It should not ask to login to download BSP sources. @AlexCo, please give it a try

after I reflash the jetpack 4.4 with sdkmanager, it report error . the error stop install components.
please see the log:

Thanks a lot @suhash for solving the access issue, works very well now.

@Mike_deng,

Your issue is probably same as

Please check.

@WayneWWW I do face the same issue, but then the issue is not the location and the NTP, I have mine set properly and updated. Could you please help me with this?
