Hardware and Software environment

- Hardware environment
  - The chip pins and the SPI FLASH are connected as follows:
    - SPI_NSS (PA3) pin is connected to SPI Flash CS (pin1)
    - SPI_SCK (PC5) pin is connected to SPI Flash CLK (pin6)
    - SPI_MISO (PD2) pin is connected to SPI Flash DO (pin2)
    - SPI_MOSI (PD3) pin is connected to SPI Flash DI (pin5)
    - SPI Flash WP (pin3) is connected to Vdd
    - SPI Flash HOLD (pin7) is connected to Vdd
    - UART1 (PD5, PD6) is connected to PC serial port

How to use it ?

In order to make the program work, you must do the following :

- Open SPI_Flash.uvprojx from this example folder by Keil MDK5
- Rebuild all files and load your image into target memory

- Run the example
