Hello Jose,

No, the FRDM-KL25 integrates the OpenSDA and you can download and debug CW applications

Hello Jose,

all the FRDM boards come with OpenSDA as on-board debug interface (of course you can use as well any SWD Debug device too). With the OpenSDA you can either load a program with the USB bootloader, or use debugger to download/program the KL25Z. CodeWarrior is just one of many supported debuggers.

More details on OpenSDA: OpenSDA on the Freedom KL25Z Board | MCU on Eclipse

I hope this helps.

PS: BDM stands for 'Background Debug Module' which is a debug IP block used on S12, S08 and ColdFire. For ARM based devices JTAG or SWD (Single Wire Debug) is used.

thanks for your asnwer ¡¡¡¡

i was worried, because the BDM is very expensive..

Hello

I have made some labs that demonstrate all the debugging features of Freescale Cortex-M processors using on-board CMSIS-DAP and the free version of Keil MDK tools (to 32K code)

These include Cortex-M0+ MTB instruction trace.

For Serial Wire Viewer or ETM Instruction trace (on those parts where available) you need a Keil ULINK2/ME or ULINKpro or Segger J-Link (black case)
