It might be a useful project if all you plan to do it to use this machine as a sh3 development box (serial console, CF network card, root/swap on NFS). However, if the companion chip is something proprietary, the efforts to support it will not pay off. PS: I tried to find out what is the companion chip in 54x, but I can't. "F1796" that hpcsh port page lists doesn't tell anything. There is a teardown report for 548 with all the photos at www.teardown.com, but it costs money to access.
What is the companion chip used for? Display etc?I was able to boot a NetBSD hpcsh kernel on my 545 in the past, with a small ramdisk image, and log in via the serial terminal, but the display does not work of course.
