DMA Transfer problem

Created a minimal system. And used direct commands as you suggested.

Still no luck :(. No clue on what's going on! I will try to simulate it next.

I have attached the Qsys screen shot.

IOWR_ALTERA_AVALON_DMA_STATUS(DMA_0_BASE, 0x00);

IOWR_ALTERA_AVALON_DMA_RADDRESS(DMA_0_BASE, SDRAM_0_BASE);

IOWR_ALTERA_AVALON_DMA_WADDRESS(DMA_0_BASE, SDRAM_0_BASE+0x1000);

IOWR_ALTERA_AVALON_DMA_LENGTH(DMA_0_BASE, 128);

IOWR_ALTERA_AVALON_DMA_CONTROL(DMA_0_BASE, 0x008C);

printf("Setting up DMA\n");

while (!(IORD_ALTERA_AVALON_DMA_STATUS(DMA_0_BASE)==0));

　

printf ("Transfer successful!\n");

Results on the console:

Setting up DMA

readaddress =800000, writeaddress =801000, length =80, status =2, control =8c
