Problem with C2H

Altera_Forum · ‎12-03-2008

Hi,

I have given a long C code to C2H for converting to HDL. On first run it gives error saying something like:

Adrdress range of uart1.s1 overlaps with pll.s1, etc. In this run I used "auto-assign base address" option of SOPC builder.

When I manually configured the base addresses in SOPC builder, C2H gives different error saying:

make: *** [c2h_hdl-t] Error 254

I do not know what to do next. Why this is happening and what can be the solution. Can you give any suggestions?

When I first use C2H in nios ii 8.1,some errors occur .That is because the nios II 8.1 need a path which called "PC-NIOS_II-8.1-0.01.exe". After fix the path, I can use the C2H.
