Folks, I would like to use the 8051 derivate MAXIM DS89C4xx in one of my experiments regaring motor controlling but I am worried about the on-chip debugging capabilites. I could not find any material on this topic. Does anybody know whether the DS89C4xx series support debugging or not? Any other known 8051 derivate which features on-chip debugging and which offers an evaluation bo...

I'm trying to get a feel for what people now consider more important, optimisations or debugging ability. In the past with such tight memory limits I would have said optimisations but now with expanded-memory parts becoming cheaper I would think that debugging ability is more important in a development tool. It's is not exactly a black and white question, debug or smallused, but more a ratio...

Hi, Could any one please advice some effective debugging tools for RTEMS? I want to watch kernel signals generated between parent and child processes, share memory data interchange between multi-threads. If there is no tools like that, is there any guideline for developing these tools? Thank you very much for your attention. Sam.

Greetings. Can I write memory locations with GDB? I have been looking through Debugging With GDB and a few tutorials but can't find anything - only how to read memory and write to variables.

After several intsruments built with the 6805, I'm looking to upgrade to a more modern processor with more code space and RAM, as well as more modern debugging schemes. The 6808 series seems to fit the bill, specifically the GP32 chip. One of my biggest hangups about the 6805 is the ancient and poorly supported debugging/emulator tools (I use the Cosmic compiler which I DO like). After my ...

Watching all this discussion about debugging with an LED and such, I was wondering if anyone else writes software UARTS for debug info. I've written a 9600 baud tx-only UART for AVR's in 35 assembly instructions.

Hello All, reading some of the specs I'm still not completely sure about the debugging capabilities of a LPC21xx. Can I access memory "non intrusive" while the program is executing (like BDM in the 68HC(S)12 or the HCS08?)? Or does a memory read always interrupt program execution for some cycles? If "non intrusive" is possible: is this a standard feature of debuggers? Any genera...
