i have SOSC enabled as System clock. There is an external oscillator with 16Mhz. Now i want to check the frequency of the external oscillator. I would like to check the frequency by comparing counter values generated by independet timers based on differnt clock soures. FIRC and SOSC trigger Flextimers FTM2 and FTM3 as external clock.
The Problem is: FIRC doesn´t work with the correct Frequency (48 Mhz). If i enable SOSC and FIRC - SOSC has correct frequency and FIRC doesn´t run with configured 48Mhz frequency.
Anyone who would like to help me?
