Hardware trigger with ADC2

As others I struggle with hardware trigger of ADCs.

My base was NXP's example adc_etc_hardware_trigger_conv. It works as expected. 

Next I tried to do the same but use ADC2 instead of ADC1. I  didn't get any interrupts. I used trigger 4 instead of trigger 0 and I added an interrupt handler for ADC_ETC_ERROR. I received periodically ADC_ETC_ERROR but no  ADC_ETC_IRQ0/1 as expected.
