Problem with KDS debugging FRDM-KW40Z

I ported an example project from IAR to KDS 3.2.0, when I try to debug I get:

Thas also happens if I create a blank project for FRDM-KW40Z and try to debug it... What is going on?

 

Kindest Regards,

Carlos

Hello Erich,

Yes! I did try with Segger debug firmware (SEGGER - The Embedded Experts - Downloads ) but the .bin file seems to be bigger than available flash on the debugger chip.

I did not find the required P&E bootloader, I did download a package with a lot of versions (http://www.pemicro.com/downloads/main_downloads_temp/201611090418336442563/Pemicro_OpenSDA_Debug_MSD... ) but I cannot see KW40Z anywhere.

Please help!

Kindest Regards,

Carlos

I read in an other thread that I can dra and drop a .bin file to the DAPLink, I did, great, but I really need to debug, step-by-step and memory, how can I peek inside KW40 with KDS?

Hi Carlos Rodriguez

About Segger debug firmware, user guide says that FRDM-KW40Z uses openSDA v2.1, could you try with J-Link OpenSDA - Generic Firmwares instead of Board-Specific Firmwares? then it should works.

About debugging step-by-step and memory, could you look in the following link, maybe it could guide you in how use KDS:

Hope this information helps you
Have a great day,

Hi Carlos,

your poblem is

"Error: MCU is unsupported"

So your device is not supported by OpenOCD, as OpenOCD needs to be implemented for your microcontroller. Have you tried P&E and Segger debug firmware on the FRDM already? They should support the KW40.
