Is there a way to disable Quad IO Read(0xEB) from the flash descriptor region?
please try clearing bits 3 (Quad I/O Read Enable) and 2 (Quad Output Read Enable) at 0x108 offset. Andrey

Thanks, it successfully disables Quad I/O and Quad Outpout Read Enable. Unfortunately, I still get strange offsets after a couple thousand read commands. I contacted Dediprog, perhaps something with the SFDP is wrong. What flash type were you emulating? I require a 1.8 Volt device with >= 128Mbit size. BR Urs
