Why aren't 3/4 of my FRDM-KL25Z boards working in the Keil MDK debugger using CMSIS-DAP?
Can anyone help getting my boards working under the Keil MDK 5 debugger?
I've got four FRDM-KL25Z boards, and a couple of FRDM-K20D50M boards.
I installed the Keil MDK 5 as well as the P&E and MBED windows drivers on my Windows XP VMWare VM.
All four of the FRDM-KL25Z boards had version 1.09 of the bootloader; I updated them to bootloader version 1.11 using the P&E Micro bootloader update. Then I loaded the new MBED 2.0 (CMSIS-DAP/MSD/CDC) application. All four of the boards work in the usual MBED mode (the USB MSD and CDC devices work fine). However, only one of the four is working under the Keil ARM debugger. The other three show "No debug unit device found" in the SW Device / SWDIO dialog.
The one FRDM-K20D50M board on which I updated the bootloader (and installed the P&E msd/debug/cdc app) is also working fine under Keil (though I believe using the P&E OpenSDA interface).
Here is the version information from the Keil IDE:
