Ulink Pro - streaming trace / realtime trace

Started by citykid_x December 15, 2010
Has anyone had issues using the streaming ETM trace (real-time trace) feature offered by the Ulink Pro unit.

I cannot get the streaming trace feature to work.

I can successfully obtain ETM Instruction Trace data but it is limited to the most recent 1048576 events. It will not stream the trace data in real-time to the PC (allowing greater / vitually unlimited) instruction trace capabilities.

I am using a Ulink Pro with the 20 pin Cortex Debug + ETM connector on one of our target boards. Environment is uVision v4.13a, target CPU is LPC1768.

Have sent a few emails to Keil but have not had any feedback from them suggesting a solution.

Anyone have a similar problem???
