Problem SDRAM....Burst Terminate!!!

Thanks BadOMen. I'm still the same problem. The zs_dq_to_and_from_sdram[0..31] always retuns 0 when I call read. But the write ok.

I also include the capture Write and Read

Write CS, RAS, CAS, WE = L H L L

Read CS, RAS, CAS, WE = L H L H

In Nios

i = 5;

IOWR_32DIRECT(SDRAM_BASE, i*4, i);

printf("Write: %x\n", i);

usleep(10);

i = 5;

r = IORD_32DIRECT(SDRAM_BASE, i*4);

printf(" Read: %x\n", r);

Output

Write: 5

Read: 0
