Symbol ' xx_base ' COULD not being resolved resolved in NIOS II Ecliplse

In Nios II, system.h defines the # define Xxx_base 0x00000010, but when you write a program, call Iord (xxx_base) or IOWR (xxx_base), always prompt for type ' xxxx_base ' Could not be resolved error, recompile no, re-generate BSP also not.

In the Nios II development, added a PIO after, also re-generate, Quartus also recompile, also re-generated BSP, finally clearly system.h can find a # define Xx_base 0x94ff, However, in the. c file has not been found, with Iord or iowr always quote symbol ' xx_base ' COULD not be resolved error tune.

Here's the solution, you can try it:

Right-click mynios2_bsp = index = rebuild
