Why does the Nios® V processor software application fail to build after migrating from the previous Quartus® software version? - Why does the Nios® V processor software application fail to build after migrating from the previous Quartus® software version? Description This issue may be seen in the Quartus® Prime Pro Edition Software version 24.1 when migrating a working Nios® V processor software application from the previous software version to 24.1. After migration, there are missing macros (#define) in the newly generated system.h, associated with composed IP in the processor system. The issue is due to a software update. Before the update, the OPAQUE_ADDRESS_MAP variable is treated as true regardless of the assignment. Resolution If the OPAQUE_ADDRESS_MAP variable is false , Update the OPAQUE_ADDRESS_MAP variable to true in the *hw.tcl of the composed IP. Please refer to Platform Designer - Module Properties for more information on OPAQUE_ADDRESS_MAP .
