Micron MT25Q flash support query
Did you ever get anything helpful on this? I'm looking into it right now and am very disappointed in how this has been handled by Intel. Having to do separate FPGA builds just for the flash part is just not feasible for a remote deployment strategy. I'm using the ASMI_PARALLEL as well, and although erase is currently completely broken, I'm assuming I'll get that figured out at some point. My parts are the EPCSL512/MTQU512 but the problem seems to be the same.
To reply to my own post in case anyone else is dealing with this, I found that I could take the generated code from a module set for the EPCQL512 and another module set for the MT25QU and mash them together so that a selector input assigns the appropriate value to the few things that have differences. I have a flash value that stores which type of flash is on-board and selects the appropriate logic. Since that is not 100% reliable (using the flash to store info about the flash!) I changed our field-reprogramming software to first do a test sector in an unused area. If it can erase->write->read twice to that sector I allow the update process to proceed. I've tested on boards with both types of flash and this works. If Intel ever changes the ASMI_PARALLEL module in a good way I will need to regenerate and update my module now, but from what I've seen so far I'd rather never let it change and keep it exactly as I have it now.
This is not the most elegant solution, but it does work. I had hoped to use the silicon ID to automatically select, but they are the same for some reason I cannot begin to grasp.
