SSH Access?

Has anyone gotten ssh access over the usb-c cable on the MPC Sample? I have a custom “OS” I’d like to port to it (coming out for other machines soon) but ran into some issues with how locked-down the sample is (RK Secure Boot, etc) and don’t want to brick a sample in the process, a friend bricked (no way to recover) theirs flashing an image that had a different SPL loader, new unsigned SPL didn’t flash and old one corrupted. Any help would be greatly appreciated!!

I honestly don't think it's possible to bypass hardware-level Secure Boot, even with SSH or root access.

Correct, this is why I’m -not- trying to run my own uboot or kernel, the end goal is just to be able to run a single aarch64 binary from the current MPC Sample userspace. This is similar to what TheKikGen had to do with the Live/Force firmware (including *not* touching the same areas like Rockchip SPL to avoid an unrecoverable brick).

The application is already written, I just need a way to launch it…..
