Hi,

Device ID will help user to identify the flash device used in the application. It will change depending upon the device manufacturer. Device ID for our device S29GL01GS is as below.

Manufacture ID: 0001h

Device ID: 227Eh

You can read ID from our device by entering the CFI ASO. Please see below sections in datasheet for more information.

  • "7.2 Device ID and Common Flash Interface (ID-CFI) ASO Map"
  • "2.2 Device ID and CFI (ID-CFI) ASO"
  • "7.1 Command Summary"

Actually we have 2 flashes on 2 different boards. One is showing device id 0x7e and other is showing 0x04. How device id can vary if device name is same i. e. S29gl01gs10tf101.

Hi,

Can you replace the flash on failing board with a fresh one and check device ID?

Are you able to perform program, erase and read operations on flash with ID 0x04?

Thanks and Regards,

Sudheesh
