1. Function description
    This routine shows how to create an SPI device on the RT_Thread system and read, write, and erase W25Q128

2. Use environment
    Hardware environment: development hardware platform corresponding to the project 
    Development board:      N32G4FRH_STB V1.1 and N32G457QEL_EVB V1.1

3. Instructions for use
    Describe the configuration method of related modules; for example: clock, I/O, etc. 
        1. SystemClock: 144MHz
        2. GPIO: LED(D1)--PA8
	     SPI1: NSS--PA4SCK--PA5MISO--PA6MOSI--PA7
                     Log: TX--PA9 RX--PA10 Baud rate: 115200

    Describe the test steps and phenomena of Demo 
        1. After compiling, download the program to reset and run;
        2. This routine creates two threads in main(), test0 thread and test1 thread, test0 thread is used to control D1 250ms flashing, test1 thread read, write, erase operation W25Q128, test results printed through the serial port

4. Matters needing attention
    Connect SPI1 interface on N32G4FRH_STB V1.1 development board to W25Q128 of N32G457QEL_EVB V1.1 development board. The two development boards need to share the ground
