CycloneIII flash content / field update

Hi, I'm trying to provide the possibility to field update the Flash content, so that the FPGA can boot using new configuration data. I have a design in which there is no Nios II process...

Hello,

I think I'll try to add a NiosII processor inorder to handle the interfacing towards the incomming configuration data (SPI) and also inorder to write the configuration data using the Generic Tri-State Controller for the Flash memory.

From what I discovered so far, the ALTREMOTE_UPDATE megawizard does not write the configuration data itself to the flash memory. It does however handle the reconfiguration cycles and the error handling that needs to be performed after the new configuration data has been placed in the flash memory.

Until now I have been downloading .pof files to the flash device using the JTAG, but I don't think I can provide the new configuration data using the .pof format (or can I ?).

Perhaps the .hex or one of the other available formats format will do better when providing the bytes that the SPI interface will transfere to the NiosII processor?

Regards,
