At work I have some projects with a Fujitsu processor and when I debug I need the $15k emulator to connect to the board thru a $200 socket. I can't debug a production ready board. Emulators give you more debugging power but the fact that you need a pod and expensive socket makes it an unwanted choice.
Nexus would be a good option on ARM or AVR32 if it didn't use so many pins. The jtag debugging can be better if you have functions in RAM. With IAR you get 1 breakpoint, 1 being used by IAR. I managed to get 2 but that was with messing up with the way IAR works out. With Eclipse I like better the debuging on the AT32UC3C0512 since I have more hardware breakpoints than on the ARM and their gdb interface is quicker than OpenOCD. I bought a JTAGICE mkII, Arrow has a sale right now for $150. Debugging is real nice and it works very well with Eclipse. The nice thing about JTAGICE is that it works well on Linux as well as Windows with full support from Atmel. It would be nice if they'd release the code though. It would have been quicker for me to get it work on Mandriva 2010.0. Atmel supports Linux but not Mandriva. I think that once OpenOCD is optimized it should work just as nice on the ARM (except for the lack of breakpoints) Michel -- Tired of Microsoft's rebootive multitasking? then it's time to upgrade to Linux. http://home.comcast.net/~mcatudal _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
