What is process to program S25FL256L QSPI flash for Intel Altera Cyclone V E FPGA?

We are NOT able to program S25FL256L using Intel’s Quartus Programmer.

The error is Silicon ID not detected for device 1.

This may be similar to a post that has NOT been resolved

• “Cypress Flash Programming using Nios II - Not working” @ https://community.infineon.com/t5/Nor-Flash/Cypress-Flash-Programming-using-Nios-II-Not-working/td-p...

There are two similar posts that have been solved, which aren’t the exact issue:

• S25FL128L Cyclone V Configuration @ https://community.infineon.com/t5/Nor-Flash/S25FL128L-Cyclone-V-Configuration/td-p/361155 <-- This discussion references Application Note AN200498, which I was NOT able to find.
• S25FL256S and Quartus @ https://community.infineon.com/t5/Nor-Flash/S25FL256S-and-Quartus/td-p/117569 <-- This is an older issue from 2018, likely using Quartus Prime 17.0 as it references AN98558. The specific solution here was “to write a wrapper around the QSYS module that forced the PLL reset to always be ‘0’.” If the current version of Quartus still needs a wrapper, is this something Infineon can provide? Or should I be asking Intel?

Hi,

With the Intel Cyclone V, you are booting from Hard Processor System (HPS), then our S25FL256L Flash is not supported by Intel.

The alternative Infineon 256Mb QSPI Flash to be used is our S25FL256SAGMFI00 which is supported by Intel on the HPS of Cyclone V: https://www.intel.com/content/www/us/en/support/programmable/support-resources/devices/supported-fla...

In the thread which you are mentioning uses the Flash in Active Serial (AS) SPI configuration mode, our S25FL256L has the right features and architecture to be used on Cyclone V.

Our S25FL256L Flash is not directly supported.

Hope it clarifies your query.
