[STM32F303] ADC synchronization through TRGO2 not working on TIM1

Hi, I'm having problem with synchronizing ADC (tested 1 and 3) with TRGO2 output of TIM1.

I'm using timer link between TIM1 (master) and TIM8 (slave in combined reset-trigger mode) through TRGO, so TIM1 determines the frequency and timers stay locked - it works fine. Now I'm using OC6ref as TRGO2 source for both timers to trigger ADC conversion. TIM1 for ADC1 and TIM8 for ADC3. The TRGO2 signal from TIM8 is working fine, even setting it to ADC1 works so both of the ADCs get triggered. But TRGO2 signal of TIM1 does not work for either of the ADCs. Does anyone experienced something like that? Any advice or comment welcomed.

thanks,

karel
