Just use:

dpr_interface = (void *)(0x80000000 + DPRAM_BUFFER_BASE);

For non-mmu BSP alt_remap_uncached() should be based on that# define.

There is no point having real function calls for a lot of the 'BSP' stuff.

Of course, I refuged to 

dpr_interface =   (tDPRInterface*) ((DPRAM_BUFFER_BASE) | 0x80000000);

This sounds like something basic is wrong. What linker error are you getting?

alt_remap_uncached() is a pretty simple function in the BSP HAL/src/alt_remap_uncached.c file.

I don't have the literal output at hand, but the linker-error is clearly stating, that the alt_remap_uncached function is considered invalid with the NIOS Gen2.
