Introduction
This example performs CBUFF software trigger.
- The user memory is initialized with incremented pattern. Cache write back is done to ensure that initialized data from cache is written to memory.
- Configures EDMA channel PaRAM set with source address as user buffer and destination as CBUFF FIFO.
- DCA1000 has to be connected to EVM to capture the data sent over LVDS interface by the test.
- After the test is completed, a binary file would be captured by DCA1000 EVM which can be verified manually. If the CBUFF module triggers the frame done interrupt test is successful.
