I downloaded the source code from the official website, compiled, brushed,but my XAVIER can not enter the graphical interface when starting.
I went in through by SSH, dmesg are as follows:

Why is this? Can someone help me solve this problem?

Thanks

There really isn’t 24169723 in it, so what should I do? What do I need to configure?

#3

Some clarification may be useful…

Is the Xavier the development kit, or is it another carrier board? Was the Xavier already running L4T R32.1 (via SDK Manager 4.2)? What did you compile…was it the kernel? If it is the kernel, what was your starting config? Did you use “flash.sh” to put the new kernel in place (I am assuming this is what you added)?

#4

The problem is solved.
The reason is that the kernel version I compiled does not correspond to the BSP version.

#5

hello dinjie
i have encounter the same problem with you，i have checked the kernel version is 4.9.140，but the result is same， can you tell me whether there is other place need to change? and any other advise? thinks very much!

#6

If you have a custom carrier board, and not the development kit carrier board, then you also need the board support package (“BSP”) for that carrier board, and the release of the BSP has to match the release of JetPack/L4T/SDKM. The original post apparently had a mismatch between BSP and the JetPack used to install it.

#7

ok
i have found it and sloved this problem，think you very much。
