Hi guys,
I am working on implementing Remote System Upgrade for my Cyclone 10LP FPGA, which loads its configuration data from an external flash device (MT25QL128). I've reviewed multiple documents on RSU and concluded that I need to have two broad sections in my design: firstly, a flash controller for writing configuration data to the flash device, and secondly, a remote update IP for switching between the factory and application image. (Please correct me if I misunderstood something)
1.) Now I've been facing a problem with finding a suitable IP for the flash controller section that can access the SPI pins with the flash device. I've tried using the generic serial flash interface IP, but it supports MT25* flashes with sizes above 256Mb only. So, is there any suitable IP for this purpose that supports both Cyclone10LP and MT25QL128? Or is it possible to write a state machine for this purpose and access those SPI pins through my design (which are normally not accessible)?
2.) The Remote Update IP again doesn't have MT25QL128 in its supported devices. Some sources suggest selecting Macronix flash device with a similar density in the parameter editor gui. Does that really work or are there any better alternatives?
Looking forward to your responses, thanks.
