USBDM - BDM DeuceEFI style
Posted: Fri Apr 13, 2012 4:52 am
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...
