5.12.1. DEMO purpose
This demo includes the following functions of GD32 MCU:
Learn to use the Quad-SPI mode of SPI unit to read and write NOR Flash with the
SPI interface
GD32450Z-EVAL-V1.1 board integrates SPI5 module with Quad-SPI mode and the mode
can communicate with external NOR Flash devices. The SPI NOR FLASH is a serial
FLASH memory chip GD25Q40 which size is 40Mbit, the chip supports standard SPI and
quad SPI operation instructions.
5.12.2. DEMO running result
The computer serial port line connected to the COM0 port of development board, set the
baud rate of HyperTerminal software to 115200, 8 bits data bit, 1 bit stop bit. At the same
time you should jump the JP13 to USART, and jump the JP10 to SPI.
