Hello FRDM-KL25Z buyer

 

You are already thousands of customers who ordered this board.

In order to make your life easier, with a single place where to find relevant informations concerning this tool, I will try to collect in this post the answered questions concerning FRDM-KL25Z, found in different places like Freescale community, groups from Element14 Community or anywhere on the web ...

 

I will publish regularly (in the document section from this group) some very instructive tutorials produced by my colleague Erich Styger, which should help you to take in hand FRDM-KL25Z and its software tools (Codewarrior 10.3beta, Processor Expert ...).

 

Don't hesitate to post here your new questions that we can answer it and share it with the community.

    I did the same thing you have said and get the following error message.image

    Besides, I can not see the driver for OpenSDA in device managemet in BOOTLOADER mode. Remember that I get this error when I want to debug, still in BOOTLOADER mode after copying DEBUG-APP_Pemicro_v106-All-Freedom.SDA. When I exit Bootloader mode and connect the board again, I can see the drivers and when I try to debug I get the following error.

    I know I asked to much, can you help me with errors? or refer me to wel documented tutorial on how to debug from CodeWorrior?

    thanks!!

    Habtamu Tolera: When in bootloader mode, you cannot use the board with the debugger. The only thing the board can do is load new OpenSDA applications. You must unplug, and then re-plug in the board before the debug OpenSDA application will begin running (as you've have seen in your tests).

     

    The error about the missing memory configuration file is likely an issue with the particular project not being able to find the .mem configuration file, and is not related to OpenSDA. To check to see where your project thinks that file is at, bring up the Debug Configuration window (Run > Debug Configurations) and select the debug configuration you are using. On the "Main" tab, there should be a box that says "Connection". Click on the Edit  button next to it. That will bring up another dialog box which will have a "Target" field. Click on the "Edit..." button next to that field, which will bring up another dialog box. In that dialog box, there will be two tabs labeled "Initialization" and "Memory". Make sure the paths to the .tcl and .mem files are correct on those tabs, as that is likely where the issue is. The correct path will depend on the particular project you are using, but hopefully it'll be somewhat obvious what the error is (perhaps a hard coded address) so that you can point it to the correct address on your hard drive.

     

    Prajas John: After you have loaded the CMSIS-DAP application (and then unplugged and re-plugged in your board so that the CMSIS-DAP application begins to run then), you will no longer see anything in Windows Explorer. You will also not see the green LED turn on, except for a short blink immediately after pluggging in the board. You can follow this Keil app note for setting up a Keil project to use OpenSDA, as by default the sample code still uses the PEMicro connection. Which on a related note, you can also use the P&E Micro debugger OpenSDA app to debug with Keil as well, so you are not required to use the CMSIS-DAP debug app.
