KL25Z UART over OpenSDA port

Hi folks,

The P&E OpenSDA firmware that ships with Freedom Board KL25Z creates a virtual COM port that can be used to communicate with the target MCU as the UARTs of the two chips are connected together:

Unless I'm missing a trick, this doesn't seem to be the case with the mbed firmware.

Are there any plans to include this extremely useful bit of functionality to the mbed firmware in the future?

Thanks.

Don't worry, the mbed firmware does exactly the same :). See: http://mbed.org/handbook/SerialPC. For windows PCs you need to install drivers manually, you can get them here: http://mbed.org/handbook/Windows-serial-configuration.

That said, while I always had to do that manually, when I added my new 11u24 and KL25Z this week on my windows 8 laptop it showed a whole bunch of windows that it was searching drivers to install, which I considered stupid since I knew I had to manually install serial drivers. Yet what came as a pleasant surprise, it did actually find serial drivers itself. I don't know if it still had the driver file on my computer from last time somewhere, or if windows 8 can now automatically install mbed serial drivers, but I at least didn't need to do anything to get them.

Thanks for the pointer, must have missed that when I went over the documentation!
