BadOmen,

Thank you very much. I will try it as your guide.

Reference to the examples, I wrote my code. Care must pay attetion to the two diferrences:

1) descriptors are stored in on-chip memory, and just use a small piece of the memory in this test code. So how to solve the other ?

2) the buffers for ADC data is defined as an array, not allocate with Malloc() function.

So I beg you to check my code again, please.

Another question: how about the SGDMA data rate? In this test, the ADC is 200Msps.
