LPC-Link2 : Unable to parse register descriptor: not matched:AP_ID = 0x04770021

Hello

I use LPCExpresso 7.4 on Windows 7(64Bit) and a LPC-Link2 debug probe.

Often I get the two error boxes with the error message Unable to parse register descriptor: not matched:AP_ID = 0x04770021 right after startup.
I still can debug, but on every breakpoint I get the two error boxes again. Except the error message debugging works (but is seems to be much more slow). Sometimes there are no error messages and debugging works just fine.

Details in first error box

On the LPC-Link2 I have installed the
CMSIS-DAP LPC-Link2 debugger image

The target MCU is a LPC1227 on two different target boards (Olimex P1227 and my own).

To try to reproduce your problem, I have just tried debugging an IAR LPC1227 board, and do not see any such error.

Did you make *any* changes to you Launch Configuration, or to the connect/reset scripts?

Please post the output of your Debug Log
http://www.lpcware.com/content/faq/lpcxpresso/debug-log
It may also help if you post your environment variables (type "set" into a command prompt and select and the output)

Having done that, please try deleting your Launch Configuration and starting another Debug session from the Quickstart panel. (See http://www.lpcware.com/content/faq/lpcxpresso/launch-configuration-menu)

I deleted all my launch configurations for one of the projects and started the debug session from the Quickstart Panel. This displayed a box where I could select the debug probe. The error messages were displayed again.

This morning when I first started debugging went well. But after about 4 short sessions the problem reapeared. Closing and restarting LPCXpresso did not resolve the problem.
