Hi,
I have the code built and running on a Raspberry PI. Unfortunately, the target part I am trying to program is a Micron N25Q256. I don't see that part in the list. When I execute the program with -VV it seems to scan lots of devices. I see activity on CLK, CS, MOSI with an oscilloscope. But MISO remains logic low. When the program terminates, it just tells me No EEPROM/Flash device found.
Stupid Noob Questions:
1. Is the static level on MISO to be expected? Or should it at least toggle?
2. Is there any hope with this device? Can I perhaps force it to think the chip is smaller?
Thanks for any help or suggestions.

P.S. This device is not on a production Motherboard. It is on an ARM processor board that we are developing. The board is a new design that will not boot. I am attempting to program this SPI EEPROM to at least get into a UBOOT environment.
