Description

When running libgen with a MPMC driver with the MHS parameter C_ALL_PIMS_SHARE_ADDRESSES = 0, the following error occurs: 

Compiling mpmc 

xmpmc_g.c:27: error: 'XPAR_DDR2_SDRAM_MPMC_HIGHADDR' undeclared here (not in a function)* 

make[1]: *** [libs] Error 1 

How do I resolve this issue?

Solution

It is possible to workaround this issue by manually editing the MHS to include C_MPMC_BASEADDR and C_MPMC_HIGHADDR. Alternatively, changing the C_ALL_PIMS_SHARE_ADDRESSES to '1' and setting the required C_MPMC_BASEADDR and C_MPMC_HIGHADDR parameters will also resolve this error. 

This issue will be partially fixed in EDK 11.2 with MPMC v5.02.a by using C_PIM0_BASEADDR and C_PIM0_HIGHADDR when using C_ALL_PIMS_SHARE_ADDRESSES = 0.  

A more complete fix is currently planned with the newest MPMC released in EDK 11.3.
