Update
I decided to compile everything (instead of downloading pre-compiled files from their repositories) and follow this repository's wiki as closely as possible.
The new file structure is as follows:
Unfortunately, the kernel panic persists. If anyone knows how to fix this, please let me know.

Issue fixed: All I needed to do was add an
initramfs.cpio.gzinto thelinuxfolder. Renaming rootfs.cpio.gz does the trick.ParzivalWolfram commentedon Jan 5, 2025
This is a bug I intend to fix soon, but the current version of the arm toolchain needed to build the firmware is too new, and my attempts at adding it to buildroot haven't yet panned out. At some point soon, you'll only need to download the buildroot repo and that will build everything you need.

Separate question, how do I fix this issue on my old 3ds (us not regon swaped)

You'll need to update your version from source, this is a bug in the popular but severely out of date version floating around.

This looks like you used the wrong DTB file. You'll need the CTR version, not the KTR version, on that device.
Trent525 commentedon Mar 5, 2026
I used the crt version, that is what the problem is on. Where should I download the updated krt version for the new 3ds
Trent525 commentedon Mar 6, 2026
I just updated my firmware and it still has the same error of not providing me the keyboard
