We are using STM32F479 processor in our design. We want to calculate the CPU load using Ulink Pro. We are unable to get the performance analysis using ulink pro when the system clock is 168MHz (system_stm32f4xx.c - (DFP 1.0.7)). If the system clock is configured to 140 MHz or lesser, it is working. Could any one please help to sort out the issue. One point is, we have select device as STM32F439 in keil since we are using older version of keil and it supports processor only upto STM32F439.
