I am having trouble with BF707 UART with DMA configuration. I used the register Mode DMA Transfers. I used the HW ref Manual for the settings. The settings work sometimes and sometimes I see the DMA_STAT_IRQ bit being set and DMA transfers are not successful. The DMA_STAT_IRQSRC bits are shown as 0. I am using 8 bit transfer mode. The XMOD register is set to 1. The DMA_CFG is 0x00100007. The UART0 registers are set appropriately. So any pointers I can look to. Any example code for the UART DMA Config mode?
