STM32L476RG - how do I oversample a sequence of several ADC inputs?

[Clark Sann]

I have experimented with the STM32L476RG-EVAL ADC_Oversample example and the ADC_Sequencer example. They both work fine for me. But when I try to combine the two, I cannot get it to work. I always timeout in the HAL_ADC_PollForEvent() function.

Anyone have any ideas what is going wrong?
