The goal is that you have all the necessary tools and drivers installed.
You need the following:
- FRDM-KL25Z board.
- Mini USB Cable.
- Course files on a memory stick or from a shared network location. This is basically a snapshot of this repository with the toolchain and setup programs.
- A host machine (Windows, Linux, Mac might be possible too).
The FRDM-KL25Z boards already have the latest firmware loaded. If you have your own board, follow the Illustrated Step-by-Step Instructions: Updating the Freescale Freedom Board Firmware
- Install the PEMicro drivers from the folder Software/OpenSDA or download it from PEMicro OpenSDA (registration required).
- Plugin the bord with the USB connector labeled 'OpenSDA' (if you look at the board from the USB port side, this is the port on the right hand side).
- The board shall enumerate, drivers will be automatically installed, and the board shall show up as a MSD (Mass Storage Device) drive (FRDM-KL25Z).
- Install a terminal program. You can use Termite in Software/Termite or download if from CompuPhase
- Connect to your board with the COM port of the board. On Windows, the board and port should be listed in the Device Manager as 'OpenSDA - CDC Serial Port'. The labs use a baud of 38400, 8N1
- In the Termite/Terminal settings, make sure you have 'local echo' enabled, with 'Append CR' for transmitting text
There is a Windows problem with disconnecting the board while having the COM port open in the terminal program. Close the port, then unplug the board, plug it in again and then open the COM port again.
- Copy the file Labs/BlinkRedLED/BlinkRedLED.s19 to your board: it shall blink the red LED
- Copy the file Labs/Printf/PrintF.s19 to your board: it shall blink the blue LED and write text to your terminal
Congratulations, you board is working!
