MPC 5777C ADC and DMA

I have a question regards to the MCAL configuration for DMA and ADC. 

I configured a ADC group under EQADC-A ADC0, when I configure to use FIFO 0 and DMA (For DMA I configured DMA channel and callback function in the MCL module and add interrupt for DMA), it is working properly. However, when I change from FIFO 0 to FIFO 1 and apply similar configurations in the MCL module and interrupt vector table, The ADC is not triggered even through I choose the same trigger source as the one I tested when using FIFO 0. 

 

Is there any clue that I can fix this problem? 

 

Thanks a lot
