Raspberry-W25Q64

SPI Flash Memory W25Q64 Access Library for RaspberryPi
I ported from here.

https://github.com/Tamakichi/Arduino-W25Q64

Software requirement

WiringPi Library
This project uses the wiringPiSPISetup() function to initialize SPI, and use /dev/spidev0.0.
If you use it on a board other than the RPI board, you may need to change the SPI device.
As far as I know, there are these libraries.

• WiringPi for OrangePi
• WiringPi for BananaPi
• WiringPi for NanoPi
• WiringPi for Pine-64

Build

git clone https://github.com/nopnop2002/Raspberry-W25Q64
cd Raspberry-W25Q64
make

API

// Start Flash
void W25Q64_begin(uint8_t spich);

// Get status register1
uint8_t W25Q64_readStatusReg1(void);

// Get status register2(Winbond only)
uint8_t W25Q64_readStatusReg2(void);

// Get JEDEC ID(Manufacture, Memory Type,Capacity)
void W25Q64_readManufacturer(uint8_t* jedc);

// Get Unique ID(Winbond only)
void W25Q64_readUniqieID(uint8_t* id);

// Check busy
bool W25Q64_IsBusy(void);

// Set power down mode
void W25Q64_powerDown(void);

// Set write enable
void W25Q64_WriteEnable(void);

// Set write disable
void W25Q64_WriteDisable(void);

// Read data from memory
uint16_t W25Q64_read(uint32_t addr,uint8_t *buf,uint16_t n);

// First read data from memory
uint16_t W25Q64_fastread(uint32_t addr,uint8_t *buf,uint16_t n);

// Erase data by Sector
bool W25Q64_eraseSector(uint16_t sect_no, bool flgwait);

// Erase data by block(64KB)
bool W25Q64_erase64Block(uint16_t blk_no, bool flgwait);

// Erase data by Block(32KB)
bool W25Q64_erase32Block(uint16_t blk_no, bool flgwait);

// Erase all data
bool W25Q64_eraseAll(bool flgwait);

// Write data to memory
uint16_t W25Q64_pageWrite(uint16_t sect_no, uint16_t inaddr, uint8_t* data, uint16_t n);

Wireing

Winbond

The letters after the volume number indicate operating parameters.
For example W25Q64BV, W25Q64CV, W25Q64FV, W25Q64JV are all the same 8 MB flash drives, but with different maximum frequencies and speeds.
In theory you could replace slow with fast, but the other way around might not work.

• BV: 80MHz clock operation
• CV: 104MHz clock operation
• FV: 104MHz clock operation
• JV: 133MHz clock operation

W25Q80

• Manufacturer:
  Byte1 : ManufacturerID(0xEF=Winbond)
  Byte2 : MemoryType(0x40=SPI/0x60=QPI)
  Byte3 : Capacity(2^0x14=2^20=0x100000=1M Byte=8M Bit)
• First 10Byte : ASCII 0-9
• Next 32Byte : ASCII A-Z

W25Q16

W25Q32

W25Q64

W25Q128

MACRONIX

The letters after the volume number indicate operating parameters.
For example, MX25L3205, MX25L3205A, MX25L3205D, MX25L3206E are all the same 4 MB flash drives, but with different maximum frequencies and speeds.
In theory you could replace slow with fast, but the other way around might not work.

• MX25L3205 50MHz serial clock
• MX25L3205A 50MHz serial clock
• MX25L3205D 86MHz serial clock
• MX25L3206E 86MHz serial clock

MX25L32

• Manufacturer:
  Byte1 : ManufacturerID(0xC2=Macronix)
  Byte2 : MemoryType(0x20)
  Byte3 : Capacity(2^0x16=2^22=0x400000=4M Byte=32M Bit)

MX25L64

MX25L128

Eon Silicon Solution

EN25Q32B

• Manufacturer:
  Byte1 : ManufacturerID(0x1C=Eon Silicon Solution)
  Byte2 : MemoryType
  Byte3 : Capacity(2^0x16=2^22=0x400000=4M Byte=32M Bit)

EN25QH64

Note

I tested these.
But I couldn't get it working.
