[Configuration Related] Cyclone III AP Configuration

It sounds like you're following the 'AP Configuration' section of the Cyclone III handbook. All the detail you need is in there. I'm not sure we can be expected to "provide additional information" here as well.

I have one question about Passive Parallel Configuration......Is it possible we use NIOSII Processor and Cyclone III to interface with external Flash Memory without using CPLDs?

Yes. You can use the same parallel FLASH device to both boot your device and then run your Nios from. You don't need a CPLD.

Oh realli? Please give me Altera Reference Or Any design example? i m realli worried about that. I study alot of time the Altera Configuration Book, volume 1 and 2.But i cann't find. Please give me design example.

That should be Cyclone III handbook right?

yes its in Cyclone III handbook but in detail in "Altera Configuration Handbook , Volume 1 & 2".

Dear Host,

Providing you follow the guidelines in the "AP Configuration (Supported Flash Memories)" section - page 9-23 - of the "configuration, design security, and remote system upgrades in the cyclone iii device family (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/cyc3/cyc3_ciii51016.pdf)" chapter of the handbook Volume 1, specifically Figure 9-8, you will be able to use that parallel FLASH device with your Nios II processor.

Thanks sir for sharing this point.Its cleared to me regarding AP Configuration.

For PS Configuration, please see the page 9-34, "Configuration, Design Security, and Remote System Upgrades in the Cyclone III Device Family" chapter of the handbook Volume 1.
