S5PV210之SDRAM初始化

本文使用的开发板是九鼎创展的X210 iNand版本。

 

一、查阅原理图中SDRAM相关部分

S5PV210之SDRAM初始化_第2张图片

 

从以上原理图中可以得出以下信息:

(1)开发板上使用的SDRAM编码是K4T1G164QQ

(2)开发板上包括4片内存芯片,每片内存的数据总线都是16位的

(3)横向的两颗内存芯片是并联的(并联时地址总线的接法一样,但数据总线要加起来),这样连接相当于在逻辑上可以把这两颗内存芯片看成是一个32位的内存芯片

(4)每个内存端口都由3类总线构成:地址总线(Xm1_ADDR0~Xm1_ADDR13、Xm2_ADDR0~Xm2_ADDR13)+ 控制总线 + 数据总线(Xm1_DATA0~Xm1_DATA31、Xm2_DATA0~Xm2_DATA31)

 

二、查阅SDRAM数据手册

由上图可得出K4T1G164QQ的含义如下:

   K:三星内存

   4:DRAM

   T:DDR2 SDRAM

1G:1Gb(128MB)

 16:单芯片16位宽

   4:8 Banks

由上图可得出以下信息:

(1)S5PV210的内存端口信号中有BA0~BA2,接在内存芯片的BA0~BA2上,这些引脚用来选择Bank

(2)每个Bank内部有128Mb,通过Row Address(14位)+ Column Address(10位)的方式来综合寻址

(3)一共能寻址的范围是:2的24次方,也就是16MB(128Mb)的内存

 

三、查阅数据手册中内存映射相关部分

 

S5PV210之SDRAM初始化_第5张图片

 

从上图可得出以下信息:

(1)S5PV210共有两个内存端口,分别是DRAM0和DRAM1

(2)DRAM0的内存地址范围是0x20000000~0x3FFFFFFF(512MB)

(3)DRAM1的内存地址范围是0x40000000~0x7FFFFFFF(1024MB)

 

由此,得出结论:

(1)S5PV210最多支持1.5GB的内存,如果给它更多的内存,CPU就无法识别

(2)S5PV210最多支持1.5GB的内存,但实际开发板上不一定有这么多。例如X210开发板就只有512MB的内存(DRAM0端口分布256MB,DRAM1端口分布256MB)

(3)X210开发板上内存的合法地址是0x20000000~0x2FFFFFFF(256MB)+ 0x40000000~0x4FFFFFFF(256MB)

 

综合以上信息,进一步得出结论:

(1)X210开发板共使用了4片内存,每片1Gb(128MB),共512MB

(2)DRAM0对应的引脚是Xm1_xxxx

(3)DRAM1对应的引脚是Xm2_xxxx

(4)从数据总线的位数可知,X210开发板用的是32位的内存

 

四、查阅数据手册中DDR2初始化相关部分

 

S5PV210之SDRAM初始化_第6张图片
S5PV210之SDRAM初始化_第7张图片

 

由上图可知:初始化DDR2共需27个步骤。

 

综合前文所述,初始化DRAM时分为2部分:第一部分初始化DRAM0,第二部分初始化DRAM1。

 

编码实现部分只实现DRAM0的初始化,DRAM1的初始化步骤相同。

 

五、代码实现

 

1、led.c

 

#define GPJ0CON	 0xE0200240
#define GPJ0DAT	 0xE0200244

#define rGPJ0CON *((volatile unsigned int *)GPJ0CON)
#define rGPJ0DAT *((volatile unsigned int *)GPJ0DAT)

void delay(void);

void led_blink(void) {
	rGPJ0CON = 0x11111111;
	
	while(1) {
		// led亮
		rGPJ0DAT = ((0<<3) | (0<<4) | (0<<5));
		// 延时
		delay();
		// led灭
		rGPJ0DAT = ((1<<3) | (1<<4) | (1<<5));
		// 延时
		delay();
	}
}

void delay(void) {
	volatile unsigned int i = 900000;		
	while (i--);							
}

 

2、link.lds

 

SECTIONS
{
	. = 0x20000000;
	
	.text : {
		start.o
		sdram_init.o
		* (.text)
	}
    		
	.data : {
		* (.data)
	}
	
	bss_start = .; 
	.bss : {
		* (.bss)
	}
	
	bss_end  = .;	
}

 

3、Makefie

 

led.bin: start.o led.o sdram_init.o
	arm-linux-ld -Tlink.lds -o led.elf $^
	arm-linux-objcopy -O binary led.elf led.bin
	arm-linux-objdump -D led.elf > led_elf.dis
	gcc mkv210_image.c -o mkx210
	./mkx210 led.bin 210.bin
	
%.o : %.S
	arm-linux-gcc -o $@ $< -c -nostdlib

%.o : %.c
	arm-linux-gcc -o $@ $< -c -nostdlib

clean:
	rm *.o *.elf *.bin *.dis mkx210 -f

 

4、start.S

 

#define SVC_STACK	0xD0037D80

.global _start					
_start:
	ldr sp, =SVC_STACK

	// 初始化DDR
	bl sdram_asm_init
	
	// 重定位
	adr r0, _start  				
	ldr r1, =_start 	
	ldr r2, =bss_start	
	cmp r0, r1			
	beq clean_bss		

copy_loop:
	ldr r3, [r0], #4    
	str r3, [r1], #4	
	cmp r1, r2			
	bne copy_loop

clean_bss:
	ldr r0, =bss_start					
	ldr r1, =bss_end
	cmp r0, r1				
	beq run_on_dram			
	mov r2, #0
clear_loop:
	str r2, [r0], #4		
	cmp r0, r1				
	bne clear_loop

run_on_dram:	
	ldr pc, =led_blink				

	b .
