You make some good points. The Nohau emulator may indeed offer many advantages over the P&E debugger ..for a price. Notwithstanding, many users, including myself, find that the P&E debugger/cable offers very good value. Some people drink beer, and some can afford champaigne. It would be interesting to hear about users experiences with other debuggers and BDM modules. Maybe us beer drinkers should consider coolers, or even champaigne.

Hi, I guess the Nohau's argument will be valid if your are working for a company and the boss is breathing down your neck for results - just suggest that 'other' more productive tool for $2000 and if he does not quickly back off, you might consider yer self a new toy commin soon. However if you work for yersleves, I guess you can try it on your spouse - or skip a coupala beers.

I think that's probably the key. There are a large number of problems with the P&E BDM modules, some serious and some minor. Support is one of them. [We sent them a question about four weeks ago, and never got an answer. Fortunately, we really no longer expect one, as we have several left over from two years ago.] Right now our biggest problem with the P&E BDM is that it will not support moving memory (and RAM) around on the D60A. Just crashes or hangs. Now that we know it, we at least can work around it... but it would have been nice to have known up front. And it would be nice to think that there would eventually be upgrades and improvements -- get the help files fixed, add some more command options (like being able to do a "BR variable+nn"). But I am pretty sure P&E considers this to be a "matured" product. I haven't seen anything change on it in years. Still, and I sincerely believe this, the P&E BDM is a great value. For 10% of what many of the others cost it does 90% of what they do. That makes it an important product for many small shops, and one that I would (with caveats) highly recommend. jmk ----------- James M.

Hi Bob, About expiriences - I hate waiting 2 weeks for new chips. I hate waiting month for tools too. And my BDM debugger/flash burner is produced by PICDEM_board+PIC16F876+MAX232+cables+some_houers_of_fun Ltd . There's great support - just think about new feature or uncommon target reset driver and you have it . Burner eats everything: aligned/misaligned/20 and 80 bytes per line S records are equally good programmed. Disadvantages: only D60A and Dx128A supported but it's because nobody asked support team. I tried NoICE with this and it works (noice serial protocol).

Elektronikladen ComPOD12, available from MCT Elektronikladen GbR (http://www.elektronikladen.de/noicebdm12.html) Technological Arts microBDM12SX, available from Technological Arts (http://www.technologicalarts.com) Kevin Ross BDM12, available from Kevin Ross (http://www.nwlink.com/~kevinro/bdm.html) P&E CABLE12 and MULTILINK, available from P&E Microcomputer Systems (http://pemicro.com) Axiom AX-BDM12, available from Axiom Manufacturing Company (http://www.axman.com) The first three are serial devices. Slower than parallel port, but happy with longer cables from the PC, and no driver voodoo or port compatibility issues. The parallel ports ones generally work well, but Billy G. keeps making it harder to connect widgets to parallel ports, and has decreed the eventual end of both parallel and serial ports on PCs. There is a crying need for a USB BMD pod for under $300, but I don't know of any. Has anyone else heard of one? Best regards, John Hartman NoICE Debugging Tools http://www.noicedebugger.com |

John, thanks for the survey. We also need the debuggers to support the s12 PLL running faster than 8MHz. (Motorola bugs 'n all.) cheers.

It is ridiculous that the P&E Multilink cable still requires a standard
parallel port. Throw in XP and we have not been able to get our cable to work yet It will work under Win 98 but fails under XP even with the port configured to use interrupts. The other issue I have with a standard parallel port is the only one you can have is the one built on your mother board. Under XP if you install a PCI parallel port you will be unable to set it to the standard I/O address for the standard parallel port. This is fine if you can dedicate your computer to every development project. What if you need more than one BDM cable that requires a standard parallel port. Then you have to use an A/B switch but if your pod is powered you can damage the emulator pod or the computer if you forget to power off between changes of port. Rod Niner .

Seems like most of these problems would be solved with a USB-based BDM device. I hope that P&E is working very hard on such a device. 607-656-2597 -----Original Message----- From: [mailto:] Sent: Friday, January 10, 2003 7:41 AM To: Subject: RE: [68HC12] M68KIT912DP256 It is ridiculous that the P&E Multilink cable still requires a standard parallel port.

Hi Bruce, HCS12 parts are supposed to derive the BDM communications clock directly from the crystal so changes in the bus speed via the PLL should have no affect on BDM SYNC. This worked fine in earlier versions of the DP256 and I believe it works fine in all of the other HCS12 parts. However, MCS912DP256 (and DT256, DJ256, DG256) mask 2 (0K79X) and 3 (1K79X) a new problem was introduced (2001) and errata was issued "BDM LOSES SYNC WHEN USING PLL AT HIGH FREQUENCIES" http://e-www.motorola.com/brdata/PDFDB/docs/MC9S12DP256BMSE3.pdf As a result of this errata, both Cosmic and P&E modified their tools. The Cosmic ZAP BDM debugger includes an option for chips with this errata that allows transparent debugging through a PLL bus speed change. The SYNC option has actually been in use for over a year. The debugger/cable also work with the more standard BDM SYNC which is the default out of reset.

Hi Dave, all, the ComPOD12 works well over a USB/serial adapter, e.g. using this combination: http://www.elektronikladen.de/en_starprog.html http://www.ftdichip.com/us232.htm Happy HC(S)12ing!
