ARM7 can do more or less the same thing by using a length of 8 words, which covers the entire vector table.

Hi Michael, hi all There is setedit that uses gdb. I haven't tried the one on windows Cool :-). Looks like Borland C++ 3.1, that i have used some decades ago with DOS 5.0 :-))). Since i use midnight commander a lot, this is really an option :-). kdbg would be nicer. insight sucks. If someone would come up with something that looks like IAR or Raisonnance that'd be neat.

It costs about $1500 per year for support. Yes, i know. I use a lot Lauterbach and PLS. They are in the same region. Nonetheless, this is a private project so i don't want to spent too much money in it. Raisonnance is a lot cheaper. I don't know about the ARM version, the one I bought is for the STM8 for around $1400. Far away for private use and i don't think that i really get something that would be so much better then OpenOcd. The NXP jtag interface is pretty annoying and i don't think that IAR can do much more with it (without Traceport) then OpenOcd. Debugging was once cool with real emulators, with jtag, bdm or whatever, it always sucks a bit.

Carsten Breuer a écrit : Debugging was once cool with real emulators, with jtag, bdm or whatever, it always sucks a bit. Best Regards, Carsten I dislike the emulators. 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.
