It's Winbond W25Q64JWZPIM https://www.winbond.com/hq/product/code-storage-flash-memory/serial-nor-flash/?__locale=en&partNo=W25Q64JW
We are verifying the write protection on W25Q64JWZPIM and run into an issue that spi_nor_sr_unlock() always return success even if HW & SW write protection are both enabled.
