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,
