Debugging on PCA10004

[Andre Lochner]

Is it possible to use the J-link to debug a stand-alone PCA10004 ? I am not using the motherboard. Powering the board separately. When I try and run debug in Keil I get error

• JLink Info: Could not measure total IR len. TDO is constant high.

Hi Andre,

The error indicates that you have setup the programmer in JTAG mode. Try going into settings for your debugger (Options for Target ... -> Utilities -> settings) and set "Port:" as SWD.
