Hi,
I am using the JLINK_ARM_ETM_IsPresent() function from the SDK with a J-Trace on a K21F tower board. K21F supports ETM, but the function keeps returning 0, indicating that there is no ETM unit present.
The Trace LED on the J-Trace is not on, even though Power, USB, and Target Power are on. Do I need to do additional setup on the device side? I am largely following mcuoneclipse.com/2016/11/05/tu…p-kinetis-arm-cortex-m4f/ as an example.
I am using SEGGER J-Link Commander V6.00b and Firmware: J-Trace Cortex-M Rev.3.
Thank you.
