have anyone ever programed several .elfs and a .sof into flash in multi-processor system? i doubt that more niosii cores can't boot in the single flash by different base address at the same time because of only a cfi interface. whether my doubt is correctly? i follow multiprocessor tutorial to successfully test two niosii cores in the multiprocessor debug of nios ii ide. could anyone have any suggestions to me?

Hi,

The multiprocessor tutorial from Altera do not cover in effect the flashing of a multiprocessor design on the Evaluation boards. Basically, you need to take care of the addresses you choose in SOPCBuilder, in a way that they do not overlap different flash blocks. Then, you can do everything from the Quartus II flash programmer.

FYI, we released today an updated tutorial, which contains some informations and screenshots about flashing a multiprocessor system. You can find it at the erika enterprise and rt-druid literature page (http://www.evidence.eu.com/nios2/literature.asp) on the Evidence web site.

Regards,

Paolo
