Probably you don't even have a usable bootloader. Then you are back at using JTAG to bitbang the FLASH or poke a kernel image into RAM, set the CPU PC to the entry point of the kernel and releasing the CPU HALT... Once you found a way to get code onto the target build a cross tool chain and compile a stock Linux kernel for the CPU architecture of the target. Try to adapt the driver for the console to your target hardware and boot the kernel. Repeat this until you have a working (serial) console. Then work your way through the other drvice drivers. I'd use NetBSD instead of Linux. Cross building NetBSD (kernel and complete user land) on any POSIX platform is a piece of cake. The kernel code is much nicer to work on, the code more readable, better organized and multi architecture support is well implemented, as its one of NetBSD design goals. Also NetBSD tends to support many older machines that Linux abandoned. (sun4c, e.g.) -- \end{Jochen} \ref{http://www.unixag-kl.fh-kl.de/~jkunz/}
