In addition to earlycon serial output, v2 includes a serial console driver RFC. Guitar output is coming further along thanks to a new timer implementation, but is still earlycon only - to be investigated. Bubblegum-96 reaches an initrd, but a small part of the serial output just before is lost (visible in dmesg). https://github.com/afaerber/linux/commits/bg96-next Booting from U-Boot is straightforward on both boards: https://en.opensuse.org/HCL:Guitar https://en.opensuse.org/HCL:Bubblegum-96 Have a lot of fun!
