Flash 8 Click

[Dragan_Stefanovic]

Flash 8 Click is a compact add-on board representing a highly reliable memory solution. This board features the GD5F2GQ5UEYIGR, a 2Gb high-density non-volatile memory storage solution for embedded systems from GigaDevice Semiconductor. It is based on an industry-standard NAND Flash memory core, representing an attractive alternative to SPI-NOR and standard parallel NAND Flash with advanced features. The GD5F2GQ5UEYIGR also has advanced security features (8K-Byte OTP region), software/hardware write protection, can withstand many write cycles (minimum 100k), and has a data retention period greater than ten years.

This Click board™ is suitable for storage and data transfer in consumer devices, and industrial applications.

The function flash8_read_id returns the third parameter organization_id :

Code: Select all

    *organization_id = rx_buf[ 2 ];

but the datasheet correctly reports the command Read ID (0x9F) provides only two bytes as reply:

ReadID.png (52.19 KiB) Viewed 80 times

The SPI read of three bytes on FLASH 8 causes a wrap around and the Manufacturer ID (0xC8) is returned as third byte:

ReadID_SPI.png (25.27 KiB) Viewed 80 times

Is this a wanted behavior?
