Question
trouble using IAR + Segger Jtrace pro + trace functionality
Posted on July 20, 2017 at 12:25
Hi
I have designed a board with a STM32 L476Z. I am trying to get trace working.
Are there any HW design guidelines when using trace pins?
After FW download with IAR and enabling function trace, i get the following error message from segger Jlink driver:
''''Ltrace:(time since start 0.0000 021, thread RX): unknwon packet received from Jtrace. communication time out: requested 4 bytes , received 0 bytes. Abort debug session ''''
After this message Segger has crahsed and has to be power plugged.
Any idea?
