What are the options and which debugger can you recommend? What do you want to debug? Application code? Then you should do fine with gdbserver on the target and GDB / DDD on the host. Kernel code? Are you looking for a BDM based debugger? There is no perfect solution available right now. There are some pretty good, but expensive professional solutions that run on the Linux host (for instance, by Lauterbach and ETS), but they do not include any special support for the Linux target - especially, they do not support the MMU (so you will not be able to do kernel source code debugging once the MMU is on, which is pretty early). There are some cheaper solutions (MacCraigor) with similar problems. Several people built their own debugger interfaces.
