i.MXRT1060 ADC external trigger (ADC_ETC) for ADC 2

There are two instance of ADC in i.MXRT1060. I can make ADC 1 work with external trigger on pin J11 GPIO_AD_B1_00 using ADC channel 5. This pin can also work with ADC 2. I can make ADC 2 work fine when using software trigger, but I can't make it work with external trigger. I think it has something to do with the TSC. I did try to set ADC_ETC.TSC_BYPASS and  ADC_ETC.EXT0_TRIG_ENABLE. Any idea why I can't make ADC 2 work with ADC_ETC on this pin?

Thanks,

Cedric
