Percepio has just released Percepio View, a new simplified version of Percepio Tracealyzer, provided free of charge also for commercial use. No registration is required.
A reference project for Percepio View is found in CORTEX_MPS2_QEMU_IAR_GCC, supporting both GCC and IAR. This runs in the QEMU simulator, so no development board is needed.
A big thanks to the FreeRTOS team for your support and for highlighting Percepio View on FreeRTOS.org.
