Post subject:  USBDM - BDM DeuceEFI style

Ok, so after chatting with people on IRC it came to my attention that we needed a way to program the Serial Monitor onto the MCU without having to already have a BDM device, so here's my contribution...

A USBDM that can be made from a single sided PCB that you can etch at home if you have the materials to do so. There are only three (3) wire jumpers to run, or if you have a PCB manufacture make a batch my KiCAD files show the traces on the component side with the vias.

The Freescale MCU on the USBDM is programmed via the USB port using Freescale's GUI Bootloader, so you don't need a BDM or Serial port to go from a blank board to a working BDM.

I will upload the details and the KiCAD files to my github.com repository in the next couple of days and post a link in this thread when they are available.

Happy Debugging...

Very cool, fully DIYable BDM :-)

Here is the link to my repository for my version of the USBDM:

https://github.com/DeuceEFI/USBDM

Instructions of how to load the USBDM firmware onto the Freescale MCU will follow soon.

Nice !
I look forward to testing it out

I have updated my github.com repository with instructions on how to load the USBDM firmware onto a blank Freescale HC9S08JS16CWJ MCU.

Freescale only offers a Windows only loader to program a blank MCU, but after the initial load you can use the Bootloader program that is part of the USBDM package for future firmware upgrades.

I think I read somewhere that you could use the same Bootloader program from the USBDM package for the initial load, but as I have no more USBDMs to build at the moment I can't test this theory. If you are able to load the USBDM firmware without the Freescale Bootloader GUI, please reply back to this thread.

Happy Debugging :-)
