Guidance on using an MCU and generic flash as an EPC1QC20 replacement

Hi,

 

I'm looking to use a generic flash and small micro as a replacement for the EPC1QC20. Specifically using Passive serial with an SPI interface. Is there any guidance documents or example code on this? 

 

Thanks,

Jack

Hi Hareesh,

 

Thanks for getting back to me.

 

Unfortunately, The device I am trying to program is a FLEX 6000 so the generic serial flash IP is unavailable. is there any guidance on how to use a standard flash and MCU as a config device without the need to modify the existing FPGA source code?

 

Thanks,

Jack

hi 

Can you please give more details on precisely what you want? I am not getting you asking about an external device or IP of FPGA details.

 

some reference doc link sharing here.

Hi, sorry for the delay.

 

I'd like to use a standard flash memory such as MX25L8006EZUI-12G Macronix | Integrated Circuits (ICs) | DigiKey as the config memory and use a microcontroller to control the configuration process. 

 

2.3.5. Passive Serial Configuration Timing (intel.com) here there is a reference to 'microprocessor as an external host'

 

I was wondering if there was any example code or an app note on this specifically .

 

Thanks,

Jack
