SSI with uDMA and Burst Mode

$

Hi,

I would like to have up to 4 (UDMA_ARB_4) and possibly 8 messages (1 per each of the 8 channels attached). However, I only see one message at a one before UDMA_MODE_STOP is reached. It does not appear that burst mode is set up correctly even though it is called in DMAInit() via

   uDMAChannelAttributeEnable(UDMA_CHANNEL_SSI0TX, UDMA_ATTR_USEBURST);

DMAInit() is called once during startup. Functions: do_dma() followed by reprime_dma() get called every 30us. Please review my code and let me know what I could do to properly send multiple messages with each DMA transfer.

Thanks, Derek
