Nand Flash映射地址的问题
/** Values specific to the LUMIT4510 board (used with s3c4510 processor)
*/
#define REG_IOPMOD (*(volatile unsigned *)0x03FF5000)
#define REG_IOPDATA (*(volatile unsigned *)0x03FF5008)
#define NAND_FLASH_ADDRESS 0x07fd8000
/*
The connections for the NAND flash on lumit4510 board are as follows:
RB<-> GPIO7
CLE <-> GPIO15
ALE <-> GPIO13
CE<-> GPIO11
#define RB (0x80)
#define CLE (0x8000)
#define ALE (0x2000)
#define CE (0x800)
这个值#define NAND_FLASH_ADDRESS 0x07fd8000
怎么得出的 请指教
这个时从CoryXie大侠的代码中看到的 仔细看一下原理图,然后对比 usb、数码管的片选信号看看。
