[seL4] Custom kernel for x86 VM

Hi! I'm Alberto, and I'm currently working on my Telecommunications Engineering thesis, which focuses on building a secure system using an seL4 virtual machine. Right now, I'm trying to use the minimal app from the camkes-vm-examples repository with a modified Linux kernel (v6.12.9) built using Buildroot. To do this, I've been replacing the kernel and rootfs files in the vm-linux/images directory with my custom ones. However, this has led to multiple errors during execution. I’d really appreciate some guidance on the correct way to integrate a custom kernel into the CAmkES VM framework. Specifically, should I be using the functions provided in the linux-source-helpers.cmake file to update the kernel and rootfs? Thanks in advance!
