Incompatible SPI Flash Configuration Device

Jump to solution

Hi All,

I made a mistake and assumed all SPI Flash storage devices worked with a 7 series Spartan (XC7S25-1FTGB196C) so I used a Microchip NOR Flash 16M Serial Flash 50MHz (SST25VF016B-50-4C-S2AF) arranged in a Master SPIx4 configurations. To my horror it seems that Vivado refuses to even attempt to try program this device. 
My question is about the log:

Mfg ID : 0   Memory Type : 0   Memory Capacity : 0   Device ID 1 : 0   Device ID 2 : 0

 

Does this mean that it didn't detect a Flash at ALL or does it mean that the device did not match? I am ordering a pin compatible device that's on Vivado's list (thats NOT obsolete) to verify this but I'm concerned that I may have done something else wrong.

Kind Regards,

B

Changing the SPI device to IS25LP016D fixed the issue.

Mfg ID : 9d   Memory Type : 60   Memory Capacity : 15   Device ID 1 : 0   Device ID 2 : 0

I do wish I had a little more flexibility with Flash components.
