He wants to transmit the data from SPI master with using DMA.
In your SPI_SLAVE_EXAMPLE_XMC4500 project, there is SPI_MASTER app
and may select DMA for transmit;
After selecting the “DMA”,
Additional DMA Instance is required or use existing instance.
An error dialog will be output no matter which one I choose;
Would you please give me your advice how to fix this?
You will need to unselect the pins configured for SPI_MASTER. After that enable the DMA. The reason is that with the original configuration, because of the pin configuration, both SPI_MASTER and SPI_SLAVE uses the same USIC module, USIC1. USIC1 has only two trigger signals to the DMA which are already consumed by the SPI_SLAVE.
