This demo is based on the GD32307C-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 the operation fails, this demo will print
out the failure information and light on LED4, otherwise print out the ID information.
Secondly, write and read the NAND memory. If the test result is correct, LED2 will be
turned on and the data writed to the NAND will be printed out.
D0,D1,P3(EXMC_D2),P2(EXMC_D3),D4-D7,nwait,A16(CLE),A17(ALE),NWAIT,NWE,NOE and
JP24(NAND_CS/NCE1) must be fitted.
