3. M2m_continue_mode

3.1. Function description:

This demo shows memory to memory data transfer working in continuous mode.

The source & destination address is increasing automatically:

• Enable global interrupt & register UDMA interrupt.

• Enable full & half transfer interrupt.

• Initialize & configure the udma.

• Start dma data transfer.

• Compare the data in destination address with the data in source address after trigger full or half interrupt.

• Repeat 10 times to verify the ccorrectness when working in continuous mode.

3.2. Main Configuration:

3.2.1. Udma m2m configure

Mode	Buffer size	Des address mode	Src address mode	Src width	Des width	Channel
continuous	64 bytes	increasing	increasing	32 bits	8 bits	CH0

3.3. Test result:

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

3.4. IO connection:

None
