Hey, I was recently tasked with installing a modified version of the upstream 5.4 linux kernel to the Nvidia Jetson AGX as part of a research project at my university. I decided to first attempt to install the vanilla 5.4 linux kernel by following the guide here: Running a mainline linux kernel on the NVIDIA Jetson Xavier AGX.
Once I flash the device, it seems to get stuck on the nvidia logo during bootup. I’m wondering what the problem could be? I have my flash log attached in case it helps.
I’ve only see flash log to indicate you’ve update device tree blob.
please also setup J501 to use micro-USB connector provides access to the UART console, you should gather the bootloader logs for reference,
thanks
After entering “dmesg --follow” and plugging in my usbc connector to j501, there is no change in the dmesg output. The nvidia logo remains displayed on my monitor connected to the jetson xavier agx.

hello charlh7,
according to below,
I think you did not update kernel image correctly, it’s still using kernel-4.9 release via buildbrain.
please update /rootfs/boot/extlinux/extlinux.conf to remove LINUX entry and re-flash the board to try again,
thanks
