As some of you might know, the mbed compilation system was out for a number of hours last night. And coincidentally it was at the very time I thought I would take a break from what I was doing an tinker with my mBuino.
One thing I had not tried yet was to setup an offline build environment, since Em::Blocks now has an importer for mbed projects I thought I would give it a try. One of the best things I ever bought was my little J-Link EDU (Thanks again Gus for pointing me in that direction in the days of the DL40) four after a few minutes of configuration I was up and running with full debugging.
I was also able to get uVision compiling and running code on the mBuino.
Next I want to try using CMSIS-DAP, esp. from Em::Blocks using OpenOCD that has the potential to provide a completely free software stack for offline mbed development with debugging, assuming I have understood the premise of CMSIS-DAP correctly. But right now my trusty J-Link is doing the trick.
Update : Added a quick and dirty image showing how I connected the J-Link to the mBuino
