2. M2m_burst

2.1. Function description:

This demo shows the function of burst transfer in memory to memory mode.

The source & destination address is increasing automatically, and dma working in normal mode with burst transfer:

• Initialize & configure the udma.

• Configure & enable burst transformation.

• Start dma data transfer.

• Compare the data in destination address with the data in source address after transformation done.

2.2. Main Configuration:

2.2.1. Udma m2m configure

Mode	Buffer size	Des address mode	Src address mode	Src width	Des width	Channel
normal	256 bytes	increasing	increasing	16 bits	16 bits	CH0

Note

The destination burst numbers need to less than the depth of FIFO_DP.

2.3. Test result:

If the data writted to buffer by DMA is same as the source data, then print pass, if not print fail.

2.4. IO connection:

None
