unable to reach __alt_heap_limit (at xxx) from the global pointer (xxx) - unable to reach __alt_heap_limit (at xxx) from the global pointer (xxx) Hi, I am porting a legacy NIOS2 project from Cyclone III to Cyclone V and getting a warning warning: unable to reach __alt_heap_limit (at 0x5ff800) from the global pointer (at 0x4573cc) because the offset (1737780) is out of the allowed range, -32678 to 32767. The code is "initializing" the heap and iterating from __alt_heap_start to __alt_heap_limit. Looks like a 16-bit pointers limitation. Any idea what is the problem? Thanks!
