Development board faulty? - FRDM-KL02Z

markadamson — Thu, 22 May 2014 14:22:05 GMT

Been using this development board for about a day now. Followed the quick start guide and managed to load the sample projects supplied. However, none of them seem to be working. I do see a small black dot on the RGB LED, so am I right in assuming that that's blown?

I can enter the boot loader just fine, updating the firmware etc. The green LED flashes so I know that that's working.

Is there a way to check if the board is broken or faulty?

Many thanks :smileyhappy:

I have attached a binary for the FRDM-KL02Z which flashes the multi-colour LED as follows:

- 5 flashes GREEN

- 5 flashes RED

- 5 flashes BLUE

and repeats.

You can load the binary using CW10.x flash utility and then see whether one of the colours doesn't work on your board. Don't forget to cycle the power to the board after loading so that the new code starts.
Ensure that you hav eloaded th emost up to data debugger to the board (eg. MSD-DEBUG-FRDM-KL02Z_Pemicro_v114.SDA)

Hi Mark,

One way to determine if your board is working is using OpenSDA to load an application that communicates through UART and see if the board is responding.

Download the OpenSDA drivers from http://www.pemicro.com/downloads/download_file.cfm?download_id=301 and install them
Enter your board in Bootloader mode (see how using this guide http://cache.freescale.com/files/32bit/doc/user_guide/OPENSDAUG.pdf ). Drag and drop the DEBUG-APP_Pemicrov108.SDA file attached.
Wait 10 seconds, then disconnect and reconnect the USB cable. Open the Device Manager. You should be able to see the following devices.
Annotate the COMM port number assigned to your device.
Download and install CodeWarrior 10.6 from Freescale WebPage http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=CW-MCU10&fsrch=1&sr=4&pageNum=1
Download the attached application to the microcontroller using CodeWarrior.
Open a serial terminal emulation program (like RealTerm or Teraterm). Configure it to use the COMM port number obtained on step 4.
Run the demo software on CodeWarrior. The characters written to the serial terminal emulation program will be echoed.

This will let us know if the Debugger and the MCU are working.

Thank you everyone for your help. I managed to get the example projects that were provided to work. The board didn't turn out to be faulty which is good news.

Thanks again
