6. M2m_lla

6.1. Function description:

This demo shows linked-list function after finished the last transmission in repeat mode.

linked-list configuration changes the source & destination start address:

Enable global interrupt & register UDMA interrupt.
Enable full transfer interrupt.
Initialize & configure the udma.
Configure the linked-list function.
Set transfer repeat times equal to 4 and address substraction value for next transmission, then start dma data transfer.
Waiting the last transmission in repeat mode, then compare the data in destination address with the data in source address.
Waiting trigger the linked-list interrupt, then to compare the data in destination address with the data in source address.

Mode	Buffer size	Des address mode	Src address mode	Src width	Des width	Channel	saum	rsau	daum	rdau
repeat	256 bytes	increasing	increasing	32 bits	8 bits	CH0	SUB	64	SUB	64

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