Hi,

I plan a NIOS-based system, that will use the remote update feature, to receive a new configuration file from an external card. I'm using a Cyclone III FPGA that will burn a P33 Flash in AP mode. I understand I need an application to run on the NIOS-based system (right?), but I need to adapt it to communicate with the externall card through a local bus, and by an alraedy made protocol. In this protocol I receive a block of bytes and burn them to the Flash. Afterwards I release the flag, to the extrenal card, receive another block of bytes etc.

Do you have the source files for this application? Did someone write such an application to communicate in the above prtocol with the external card?

I'll be gratefull if you could send me those source files.

Best Regards,
