KL25 FREEDOM : unable to debug with CODEWARRIOR

[teddychin]

Good afternoon

i have a problem with my freedom (or PC installtion) in order to be able to debug.

The only thing which is working is the BOOTLOADER (MSD application) where i can send SREC/S19 FILES.

If not, the OPENSDA LED is blinking with ERROR code each time i try to upload the DEBUG application on BOOTLOADER mode.

Windows isn't recognizing the OPENSDA driver (CDC) driver, despite the fact i downloaded and installed the PEMICRO driver package.

Code warrior isn't able to see the OPENSDA debugger.

To be honnest, i'm a bit lost to enable my board in order in can download program & debug from CODEWARRIOR. Only the MSD application seems to work.

Do you, please, have an idea or a recomandation ?

i tryied many things and nothing is working :

thank you a lot

There are two different modes for the board:

- MSD bootloader mode (this is what you have right now): in this mode you can copy S19 files to be programmed

- Debug Mode: this is required to debug. For this you need to load the DEBUG-APP_Pemicro_v102.SDA so it has the PEMicro Debug App shown:

Board Name is: FRDM-KL25Z
MicroBoot Kernel Version is: 1.01
Bootloader Version is: 1.01
Installed Application: PEMicro Debug App
Application Version is: 1.02

good afternoon Erich

i already tried to copy DEBUG-APP_Pemicro_v102.SDA in the FREEDOM, in the MSD BOOTLOADER MODE.

My problem is the ERROR LED is blink (fast 8 times, pause ...) after the DEBUG-APP_Pemicro_v transfert.

Do you have an idea ?

thank you

best regards

Hi teddy,

I bet this is an error code, but I'm not aware of a description. Did you

- plug in the board with the reset button pressed

- copy the debug_app*.sda to the board

?

The debug app needs to be loaded in bootloader mode, not in MSD mode.

Apart of that: make sure you copy the file *not* with a file manager extension (like File Commander, etc) on Windows. In doubt, use the DOS shell/cmd 'copy' command.

This helped me with my problem!! I'll put this link into the discussion I made last week.

hi Erich

you are right, it seems that with the copy command it is working.

thank you for the hint, i'll continue now ..
