Problem that hdmi output is not working after applying kernel compiled image in Jetpack4.7.2 for Jetson Nano

[mszeta]

Hello,

After compiling Jetpack4.6.2 kernel source, copy the generated Image file to /boot/Image on target Jetson Nano.

Problem that hdmi output is not working after applying kernel compiled image in Jetpack4.7.2 for Jetson Nano

Since then there is no HDMI output.

Please tell me how to solve this problem.

Thank you.

Please check if the “lsmod” is empty after you change the kernel.

Please directly reply above question first. Whether this is your first time or 100th time really does not matter to me…

Hello,

I’m using the production module and I just built it without changing anything in the kernel source.

Thank you.

Please share your “uname -r”.

Hello,

uname -r

Thank you.

Hi

The issue is that you added this “_sy” when building kernel… so it does not find the path to modprobe kernel modules…
