Percepio Application Note #35 covers setting up snapshot recording for Tracealyzer for FreeRTOS in Renesas e² studio. Streaming mode over the on-board J-Link is also possible, but the focus here is on how to use e² studio.
To follow the instructions in this document, you will need a Renesas RZ/T2M or RZ/N2L target system running FreeRTOS (v7.3 or newer), and Tracealyzer with a license that matches your RTOS.
