I'm trying to use ETM trace with IAR and a J-Trace on a K66 in High Speed Run mode.
Everything works great until the switch to High Speed Run Mode. I've tried setting the SIM_SOPT2 register to set the TRACECLKSRC to 0 (This will use the MCGOUTCLK / TRACECLK divider) and setting the SIM_CLKDIV4 register to have TRACEDIV=2 and TRACEFRAC=1 for a trace clock output in HS RUN mode of 180 * (2/3) = 120, but I still am getting errors.
Are there any other tricks to switching the trace clock frequency mid debug on this processor? Are there other registers I need to set?
I couldn't find there need another register setting with K66 chip.
For I don't have J-Trace tool, I couldn't do on site test.
I will check with Segger engineer if there with any comment.
Thank you for the patience.
