Honored ContributorThanks FvM. A few more comments;
1) Regarding the "claimed possible incompatibility of third party serial flash devices", and limtzikhang's comments not withstanding, all this talk about transistor width, pinchoff voltage and doping levels strikes me as utter nonsense. The fact is, you send a PROGRAM command and wait for the return STATUS while THE DEVICE PROGRAMS ITSELF. I neither know nor care about the internal workings, the chip is designed to operate in just this fashion. 2) This leaves my original question dangling in the air; how can I have two different serial devices that will program and verify, but the FPGA doesn't configure correctly at power-up? 3) You were able to find suitable devices for AS programming up to 64Mb, would you be willing to share these with us?
