  This demo is based on the GD32F450I-EVAL-V1.1 board, it shows how to use EXMC peripheral to 
control NAND memory. This board uses EXMC_BANK1_NAND to support NAND memory. 

  This demo shows the write and read data operation process of NAND memory by EXMC module. 
Firstly read NAND_ID. If read ID failure, print out the failure information and light on LED3, 
othterwise print out the ID information. Secondly write and read NAND memory. If the access correctly, 
LED1 will be turned on and print out the the data you write to the NAND.

  JP5(USART0) must be fitted.
