Building a kernel higher than 5

Hello everyone,

I’m trying to run Buildroot on my Rock3a and I’m encountering issues with the kernel version. The latest versions of Buildroot don’t seem to support the kernel version I need. Is there any way to run a kernel like 5.15 on the Rock3a?

Any advice or guidance would be greatly appreciated!

Thank you!

Currently Armbian supports building linux 6.1 kernel

Thank you. And where can I find the u-boot compatible with that kernel?

Please refer to this configuration file:

Thank you so much!!
