Background Debugging Mode Driver Package

Wijnand — Wed, 10 Dec 2025 20:42:13 GMT

Hello CPU16/32 trainers/developers,

I started a project with my student to design a BDM interface (USB->BDM) with the Arduino IDE to (simply) monitor the SBC EC376 from Wurz. We found the document AN1230/D but we can't find the "BDM Driver Package" (BDMVx-y.ZIP) called on page 5.

Can you help us?

Thanks and regards...

Wijnand Nijs

Hello @Wijnand ,

Thanks for your post. The AN1230 is too old, I could not find related BDM Driver Package.
While I find below link for your reference, which provide BDM driver and related info.
It is not NXP(Motorola) official released, which is a private blog.
BDM Interface for Motorola 683xx MCU\\ Usage with GDB Debugger
Wish it helps.

Hello Celeste,

Thanks for your effort. We'll explore whether parts of the resources (the BDM component) are useful for our project. The goal is to design a simple monitoring program that can be used, for example, to upload s-records to the target.

Hello Wijnand,

AN1230 files can be found here:
http://archive.retro.co.za/archive/computers/Motorola/freeware.aus.sps.mot.com/mcu332/BDM-V090.ZIP

I am looking for the files on the diskette that came with the board ("ec376 Software Package" / “ec376 SWP”) and other accompanying documentation. Please let me know if you have anything.

Thank you.
