I am using the RT1170 ADC-ETC test, I hope to add DMA to carry data, I don't know where I set it wrong, I have never triggered DMA requests.I will TRIG0_ENABLE position 1, when the ADC conversion is completed, TRIG0_REQ is also set 1. However, it does not enter the DMA interrupt.

It is found that it is caused by setting the source address error, and the 0x403b0028 is modified to 0x40048028

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
According to your previous question, you already implemented ADC-ETC combine DMA function on the RT1052, in my opinion, you can port it to RT1170 easily with a bit of modification.
Have a great day,
TIC
