Is it possible to set transfer from sdram to SPI. I have set all necessary MPU regions and FMC is configured properly. When I use this with LTDC, it works fine.(not using standard DMA for that).
But, when I try to send from 0xC0000000 to SPI, DMA1.stream.MAR just ignores the value that is outside of normal DRAM. Looking with the debugger, I can see that MAR value is not changed. For other dram buffers, works fine.
