I've installed the v11.1 files for the 230K and 530K design. The earlier version of the 230K design uses SOPC builder to define the board-update-portal design. If you open the SOPC system, the ext_flash is mapped to 0x0800_0000. That is why the nios2-flash-programmer commands used to communicate with that design use 0x0800_0000 for the flash address.

The v11.1 designs use Qsys. If I open the Qsys system for the v11.1 230K or 530K design, the flash (ext_flash) is mapped to address 0 of a pipeline bridge, which is mapped to address 0x0800_0000 in the CPU address map. So, both the old and new design should work with the commands you quoted above from the user guide.

I'll update my board and post the results.

Cheers,

Dave
