A lot of people suggest to use the Abatron BDI2000 as debug system. I used the Lauterbach TRACE32-ICD system with ARM processors without MMU (no Linux) and it works extremely well. The manufacturer claims it fully supports both the MMU and the Linux kernel (see here for more details http://www.lauterbach.com/cgi-bin/docloc.pl?file=rtoslinux.pdf). Can anybody who used it confirm this point?I can. You can debug the kernel and e.g. interrupts using virtual addresses very well, you just have to specify the mapping (e.g. for ppc map phys 0x00000000 to 0xc0000000) I've not looked in detail yet to debug user processes.
We are using the TRACE32-ICD (MPC8xx) with U-Boot and Kernel 2.4.4. Kernel debugging works without any problems. User space debugging is also fine - but only if you don't have to debug shared libraries :-( I think the T32 is a very good choice for kernel debugging, especially if you have experience with the GUI and don t need the documentation or online help ;-) If the problems with the shared libs are solved you have _one_ debugger for kernel and applications.
