No Freemaster CMSIS-DAP connection to LPC5536-EVK

[AlbertoGarlassi]

Hello, I'm able to load and debug this board with MCUXpresso, the debugger is shown  as MCU-LINK on board (r0C7) CMSIS-DAP V3.108.

But Freemaster, set as "CMSIS-MASTER CMSIS-DAP Communication Plugin" and pressing "Configure" shows that no device is present.

Configuring with the communication wizard brings the same result.

This happens with a closed MCUXpresso, so the interface is not already in use.

Reinstalled as administrator: no success.

Am I missing something?

Regards

Alberto

OK thanks.

Already tested, now it's fine.

Hello,

the MCU-LINK v3.108 brings a new version of CMSIS-DAP interface (v2.1) which is not compatible with FreeMASTER 3.2.1 and earlier versions. The FreeMASTER 3.2.2 is going to support this CMSIS-DAP version soon and will also remain backward compatible with older versions.

As a temporary workaround before FreeMASTER 3.2.2 is available, you can downgrade your MCU-LINK to versions prior to 3.108.

We are sorry for the inconvenience.

Regards,
Michal
