It's actually not in that thread. I chose not to post it to the forum because I don't have the time bandwidth to respond to PM's about it. I created it in LibreCad. I think there's a version of LibreCad that runs in Windows. I don't use Windows. I use Linux.

EDIT: Found a mistake in the file. See corrected file below in next thread

Here is the corrected file (use at your own risk):

If you have a 3D printer...

I modeled it in OpenSCAD (which is free) based on the pin locations from DavidBraley's DXF.
I also posted an STL file, which most 3D printer software can probably use directly.

Good options with a 3d printer. You can also search for bdm frame and probe pens on ebay or aliexpress. Its a frame that holds some probes so that you can balance them in the points on the pcm. You need to position them one by one but for occasional use it works well. Most kits come with 4 probes so you'll need a pack of extra stand alone probes too.

That's a really cool idea, I like the flexibility.

I don't want to be a party pooper, but... I see one problem with this type of BDM fixture: Those probe pins are possibly too long.

The BDM device being used from USB BDM NT does not like very long lead lengths. I learned this the hard way. I don't have my notes handy at the moment, but I think I was told by the maker that the leads need to be less than 16cm from the contact point to the physical 5x2 plug at the BDM device. I managed to get my lead lengths less than 6 inches (15.2cm), and still had trouble at the default 3 mhz speed used in the .xml confige file. There is a way in software to slow things down, but I think 1.5 mhz is the slowest. I have since changed these config files to default to the 1.5 mhz speed and have had no problems since. Even at 1.5 mhz, the BDM will do full reads of a 1 meg flash chip is less than 10 seconds, and full erase and then write in less than 60 seconds. It's insane how fast it is.

With a little twisting, and a little tweeking it ought to work pretty good.

Gampy,

I like that device. It insures a really short path from PCM to BDM. I can't believe that stuff is so inexpensive!
