We used a serial line, an oscilloscope a text lcd and some leds to debug. It was a Pita. I want to forget. And yes, we did program in assembly. I like the 68HC11 but 20 years later... I like old systems but it doesn't seem that much survived. You see what happens, things are bought, used or not, stored and if no one knows what it is it gets thrown away in some office cleaning action :(.
Good luck.
I gave up my efforts with a coldfire BDM (I know you are looking for CPU32 BDM). I couldn't get the processor out of reset, reading and writing registers was no problem... but for more the public docu was incomplete :(

I haven't blocked anyone for sending me PMs. You may be confounding me with someone else.

judging by your silly reaction at blocking my PMs when I asked *IF* you have made any progress with the long to-do list you have written in public ... well, I frankly now believe you are not clever (I want to be polite).



What public to do list, please enlighten me as to what this is all about.

So, this project has been canceled. The hardware is ok, but it misses the software, the documentation is poor, and and I don't find collaborating/interested people.

It was one of my favorite processors a long time ago, in a line of 6+ over the many years. Unfortunately, I've tossed out / given away everything for it.
I would have had an emulator (often quite expensive back then), and likely a Motorola dev pack. I've had a quick look, and can't even find any "sample"
projects. I usually keep a few for historic reasons. Did you try Motorola legacy caches?
In cases where I've had to "dig up" an old project, on a long retired CPU, I've usually just started again with my "new" current favorite :-)
Just dig out the source code and re-adapt it. Good luck, it's a tough job.
Hello <tap> <tap> .. is this thing on?

Then accept it and move on.

I have tried to contact seniors and retired guys at Motorola. But I got no luck, and from Freescale nobody knows anything. I have issued a couple of technical requests, both closed due to the lack of information. This also includes my requests for the documentation of the DI protocol, IDP timing documentation and other stuff that we have lost in time. Fortunately, I have recently met two senior engineers involved with Motorola for a third party business. One of them worked for Beckman on spectrometers, the second is still collaborating with Ford Racing. But they are with MC683xx, CPU32.

HC11 has no good luck.

I only know someone inside the MIT's campus, but she was my old teacher of computer science and she may times ago she was on the HB11 project, that is/was a sort of Arduino board made before Arduino was made. But she has never used an ICE. So ...
