Hi, I plan to start with 2138 and I need to choose a dev. tool. Can somebody tell me his development tool (IDE,compiler,debugger) and above all his JTAG debugger (with appreciation) ? Debuggers with trace recording seems very expensive ! Does simple JTAG probe (no trace, 2 hard breakpoints) sufficient for debugging ? Thank you D. |

Hello Daniel, if you have the budget for a trace emulator, it might really reduce your development time but trace comes at a double cost. The emulator is more expensive AND you loose 10 pins. If your budget is restricted (like everyones ;-) to get started the MCB2130 from Keil in a package with the U-Link (JTAG hardware) gets you going for $299 (www.lpctools.com). Most likely though you need to upgrade to the full compiler package, don't know the exact pricing but in the neighbohood of $2k. Lower cost, in regards to the compiler would be going with GNU (www.gnuarm.com for a start). It all depends how much is your time worth to yourself and how important is time to market. With a product which needs to be fast to market you want to have tools that generate optimized code AND a phone number to call if something does not work as expeceted. We have made good experience with the Keil tools, though the compiler is still work in progress. hth, Bob --- In , "danielator2004" <danielator@v...> wrote: > > Hi, > I plan to start with 2138 and I need to choose a dev. tool. > > Can somebody tell me his development tool (IDE,compiler,debugger) > and above all his JTAG debugger (with appreciation) ? > > Debuggers with trace recording seems very expensive ! > > Does simple JTAG probe (no trace, 2 hard breakpoints) sufficient for > debugging ? > > Thank you > D. |

Hi Daniel You will get many replies to this - and each reply will reflect the tools of the responder. I use a Crossworks by Rowley (for the 2106) with a Wriggler compatible Jtag from Olimex. The Olimex hardware is cheaper than you could make it if you put any value at all on your time. The Crossworks compiler is cheaper than most - but not as cheap as the gnu tools which are free. I understand that Rowley have now updated this complier to the 2138. The source level debugging is not bad (many breakpoints allowed) I wish the tool tip evaluator for char* types would show me the string rather than the pointer value !!!! but all in all - its an efficent tool. On the other had the "debug_printf" (comes out through the Jtag without hardware or memory overhead) is brilliant. I never need trace. Hey 99.9% of the time you can run to breakpoint and look at the variables to sort your problems. I hope this helps Owen Mooney. (Kick back from Rowley would be appreciated - Nah - just kidding :-) ) Hi, I plan to start with 2138 and I need to choose a dev. tool.

The lowest cost non-GNU compiler is ours, $199. It;s in BETA2 and I plan to release BETA3 this week and the final version by end of the month.Yes, I know it's late but it will be worth it. For debugging, unfortunately, the current low cost leader is the free GDB/Insight. We have beta customers using Nohau and Lauterbach and in theory, it should work w/ any ELF/DWARF debugger. We have a low cost debug solution waiting in the wing, but we will need to release the compiler first. >Debuggers with trace recording seems very expensive ! > >Does simple JTAG probe (no trace, 2 hard breakpoints) sufficient for >debugging ? > >Thank you >D. > > >Yahoo!

Thank you for your quick responses, I try to get a user feddback about tools. I notice several complete solutions around 2/3K. (compiler+debugger/simulator) Did anybody experience with ULINK (keil) or TANTO-BASE (hitex) or TANTINO (hitex) I notice that hitex solution seam to be more powerfull ? (downmoad speed ...) |
