I have modified the "system.mhs" file as follows :
begin microblaze
// some lines of code
PARAMETER C_PVR = 2
PARAMETER C_PVR_USER1 = 0x02
PARAMETER C_PVR_USER2 = 0x0bb35
//some lines of code
End
when i build the hardware in Xps and export to xilinx SDK i do not see these parameters updated in xparameters.h. any hints ?
