We would like to know some more details about this issue.
1. How many devices are showing this issue? Are you observing it with all of the devices that you tested?
2. Can you share the waveform (SPI signals: CS#, SCK, MOSI and MISO) for write operation (WREN + WRITE commands)?
3. What is the data that you write and read back when this issue happens? Are you reading data as 0x00?
Thanks and Regards,
