gdma_lli

Overview

This project shows how to use GDMA functional APIs to do the memory to memory data transfer with link list feature.

In this example, there are 4 buffers, s_gdmaData0 to s_gdmaData3. At the beginning, only s_gdmaData0 is filled with data. GDMA copies s_gdmaData0 to s_gdmaData1, then copies s_gdmaData1 to s_gdmaData2, and copies s_gdmaData2 to s_gdmaData3. So at last the data in 4 buffers should be the same.

The project checks the data in each buffer and show the result terminal.
