14. Spi_master_slave_padma

14.1. Function description:

This demo shows master send data and slave receive data use UDMA mode, in addition, data is initialized to sram.

14.1.1. Padma configure

14.1.1.1. Master_tx_dma_channel:

Mode	buffer size	Dst Address Mode	Src Address Mode	Transfer Width
normal	40 bytes	non-increasing	increasing	32 bits

14.1.1.2. Slave_rx_dma_channel:

Mode	buffer size	Dst Address Mode	Src Address Mode	Transfer Width
normal	40 bytes	increasing	non-increasing	32 bits

14.2. Test result:

If the data of slave received is equal to master transmitted, print pass, if not print fail.

14.3. IO connection:

PAD	PAD
pad_qspin_sck	pad_qspim_sck
pad_qspin_cs	pad_qspim_cs
pad_qspin_dq0	pad_qspim_dq0
pad_qspin_dq1	pad_qspim_dq1

Note

The ‘m’ and ‘n’ in “qspim” and “qspin” indicate the peripheral number.
