一、硬件情况:
1、查看原理图:16bit模式;
2、INT接到S5PV210的IRQ_LAV/EINT10,INT脚为低时为有效中断信号,中断线为EINT10;
3、CS接到S5PV210的CSn1,CMD连接到V210的地址总线ADDR[2],故INDEX和DATA[15:0]的端口地址分别为0x88000000和0x88000004。
二、软件修改:
1、修改\kernel\arch\arm\mach-s5pv210\include\mach\map.h
#define S5PV210_PA_DM9000 (0x88000000) #define S5P_PA_DM9000 S5PV210_PA_DM9000 + 0x300
2、修改\kernel\arch\arm\plat-s5p\devs.c
static struct resource s5p_dm9000_resources[] = { [0] = { .start = S5P_PA_DM9000, .end = S5P_PA_DM9000 + 3, .flags = IORESOURCE_MEM, }, [1] = { #if defined(CONFIG_DM9000_16BIT) .start = S5P_PA_DM9000 + 0x04, .end = S5P_PA_DM9000 + 7, .flags = IORESOURCE_MEM, #else .start = S5P_PA_DM9000 + 1, .end = S5P_PA_DM9000 + 1, .flags = IORESOURCE_MEM, #endif }, [2] = { .start = IRQ_EINT10, .end = IRQ_EINT10, .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHEDGE, } };
3、修改\kernel\arch\arm\mach-s5pv210\mach-smdkv210.c
static void __init smdkv210_dm9000_set(void){ ... tmp = __raw_readl(S5P_SROM_BW); tmp &=~(0xF<<4); tmp |= (1<<7) | (1<<6) | (1<<5) | (1<<4); __raw_writel(tmp, S5P_SROM_BW); __raw_writel((0x0<<28)|(0x0<<24)|(0x5<<16)|(0x0<<12)|(0x0<<8)|(0x0<<4)|(0x0<<0), S5P_SROM_BC3); ... }
4、make menuconfig选上DM9000和16bit的模式,make zImage即可
