Problems with DMA

Hello, I need some help. I try to use DMA to control UART to send datas on memory, but it failed. #include "altera_avalon_uart_regs.h"# include <stdio.h># include <io.h># include "system.h"...

Hello,

For me you code seems ok, and the DMA should work. I also try to work with UART and DMA, in the same way as you, but it does not work. In my case, I looked the status register of DMA after to have launch the transfer, and it seems to work well because the bit LEN and DONE are set to 1, but I have nothing on the UART port.

Have you solved your problem ?
