前一篇博文:《mini2440移植uboot 2014.04(一)

(四)添加nor flash支持

我的mini2440使用的nor flash芯片型号是SST的39VF1601(16Mbits=2MByte)。该nor flash连接nGCS0。

SST39VF1601的数据手册下载地址在这里

先重启mini2440,进入官方的uboot(如果没有安装官方uboot, 可以按照《openocd+jlink为mini2440调试u-boot》将其先烧进去 )。

然后执行下面命令查看nor flash信息:

Bank # : SST: 1x SST39VF1601 (2MB)
Size: MB in Sectors
Sector Start Addresses:
(RO) (RO) (RO) (RO) (RO)
(RO)
000A0000 000B0000 000C0000 000D0000 000E0000
000F0000 001A0000 001B0000 001C0000 001D0000
001E0000 001F0000

确实使用了SST39VF1601这款芯片。

上一部分编译出来的uboot在执行时得到下面的输出:

是在识别nor flash时出错的,仔细看代码后发现jedec_table没有该芯片的定义,将其定义加入到jedec_table的末尾处:

#ifdef CONFIG_SYS_FLASH_LEGACY_1Mx16
{
.mfr_id = 0xf0,
.dev_id = 0xea00,
.name = "SST39VF1601",
.uaddr = {
[0] = MTD_UADDR_0x5555_0x2AAA, /* x8 */
[1] = MTD_UADDR_0x5555_0x2AAA /* x16 */
},
.DevSize = SIZE_2MiB,
.CmdSet = P_ID_AMD_STD,
.NumEraseRegions= 2,
.regions = {
ERASEINFO(0x1000,256),
ERASEINFO(0x1000,256)
}
},
#endif

然后将include/configs/mini2440.h中修改:

#define CONFIG_SYS_FLASH_LEGACY_512Kx16
#define CONFIG_SYS_FLASH_LEGACY_1Mx16

重新编译,然后打开三个控制台,一个执行"sudo minicom",另一个执行"openocd -f interface/jlink.cfg -f board/mini2440.cfg",最后一个控制台执行下面内容:

telnet localhost
reset
init_2440
load_image /home/host/soft/mini2440/u-boot-2014.04/u-boot.bin 0x33e80000 bin
resume 0x33e80000

得到下面的输出信息:

上面的修改方式是比较好的,改动相对来说比较小。

另外一种方法是将mini2440开发板中u-boot的board/tekkman/mini244/flash.c拷贝到当前uboot的board/friendlyarm/mini2440下,

然后在其下Makefile中添加flash.o,但是会有编译错误,提示函数reset_timer_masked未定义。这是因为二者的定时器的一些函数被删除了,

需要对代码做些调整才行。

另外一个方法是模仿m5253demo开发板(配置文件位于include/configs/M5253DEMO.h,开发板文件夹位于board/freescale/m5253demo下),

将其下的flash.c(所用的nor flash是sst的6401,跟当前的1601差别就在于容量和ID号有些不同)拷贝过来做修改,如果感兴趣,可以自己移植看看。
