mini2440移植uboot 2011.03(上)
参考博文：
《u-boot-2011.03在mini2440/micro2440上的移植》
本来我想移植最新版的uboot,但是移植却不太成功，所以先模仿他人的例子重新执行一遍，对uboot更熟悉后再开始新版本的移植。
操作系统: debian 7.4
uboot： u-boot-2011.03（下载地址）
交叉编译器：arm-linux-gcc 4.4.3(下载地址）
执行过程如下：
移植（一）基本配置：
在boards.cfg下添加一行：
mini2440 arm arm920t - friendlyarm s3c24x0
执行下面命令：
host@debian:~/soft/mini2440/u-boot-2011.03$ mkdir -p board/friendlyarm/mini2440
host@debian:~/soft/mini2440/u-boot-2011.03$ cp -r board/samsung/smdk2410/* board/friendlyarm/mini2440/
host@debian:~/soft/mini2440/u-boot-2011.03$ cd board/friendlyarm/mini2440/
host@debian:~/soft/mini2440/u-boot-2011.03/board/friendlyarm/mini2440$ mv smdk2410.c mini2440.c
host@debian:~/soft/mini2440/u-boot-2011.03/board/friendlyarm/mini2440$ vim Makefile
将Makefile中smdk2410替换成mini2440
host@debian:~/soft/mini2440/u-boot-2011.03/board/friendlyarm/mini2440$ cd -
host@debian:~/soft/mini2440/u-boot-2011.03$ cp include/configs/smdk2410.h include/configs/mini2440.h
host@debian:~/soft/mini2440/u-boot-2011.03$ vim include/configs/mini2440.h
将#define CONFIG_SYS_PROMPT "SMDK2410 # "中的SMDK2410修改成MINI2440。
添加两行内容：
#define CONFIG_SYS_SDRAM_BASE PHYS_SDRAM_1
#define CONFIG_SYS_INIT_SP_ADDR (CONFIG_SYS_SDRAM_BASE + 0x1000 - GENERATED_GBL_DATA_SIZE)
然后进行编译：
host@debian:~/soft/mini2440/u-boot-2011.03$ make mini2440_config
host@debian:~/soft/mini2440/u-boot-2011.03$ make
得到下面的输出：
............................
/home/host/soft/FriendlyARM/toolschain/4.4./bin/.arm-none-linux-gnueabi-ld: warning: creating a DT_TEXTREL in object.
arm-linux-objcopy -O srec u-boot u-boot.srec
arm-linux-objcopy --gap-fill=0xff -O binary u-boot u-boot.bin
移植(二）在RAM中执行：
host@debian:~/soft/mini2440/u-boot-2011.03$ vim include/configs/mini2440.h
删除两行内容：
#define CONFIG_S3C2410 1 /* specifically a SAMSUNG S3C2410 SoC */
#define CONFIG_SMDK2410 1 /* on a SAMSUNG SMDK2410 Board */
添加三行代码：
#define CONFIG_S3C2440 1 /* specifically a SAMSUNG S3C2440 SoC */
#define CONFIG_MINI2440 1 /* on a FriendlyArm MINI2440 Board */
#define CONFIG_SKIP_LOWLEVEL_INIT
host@debian:~/soft/mini2440/u-boot-2011.03$ vim arch/arm/cpu/arm920t/start.S
# if defined(CONFIG_S3C2440)
# define LOCKTIME 0x4C000000
# define MPLLCON 0x4C000004
# define UPLLCON 0x4C000008
# define CLKDIV_VAL 5
# define M_MDIV 0x7f /* XTal=12.0MHz MPLL=405MHz */
# define M_PDIV 2
# define M_SDIV 1
# define U_MDIV 0x38 /* XTal=12.0MHz UPLL=48MHz */
# define U_PDIV 2
# define U_SDIV 2
ldr r1, =0x7fff
ldr r0, =INTSUBMSK
str r1, [r0]
ldr r0,=LOCKTIME /* config U_LTIME and M_LTIME */
ldr r1,=0x0fff0fff
str r1,[r0]
ldr r0, =CLKDIVN /* Fclk:Hclk:Pclk = 1:4:8 */
ldr r1, =CLKDIV_VAL
str r1, [r0]
mrc p15, 0, r0, c1, c0, 0 /* asynchronous bus mode */
orr r0, r0, #0xc0000000
mcr p15, 0, r0, c1, c0, 0
ldr r0,=UPLLCON /* config UPLL */
ldr r1,=((U_MDIV<<12) + (U_PDIV<<4) + U_SDIV)
str r1,[r0]
nop /* to ensure finishing the operation, wait 7 clocks */
nop
nop
nop
nop
nop
nop
ldr r0,=MPLLCON /* config MPLL */
ldr r1,=((M_MDIV<<12) + (M_PDIV<<4) + M_SDIV)
str r1,[r0]
#else
/* FCLK:HCLK:PCLK = 1:2:4 */
/* default FCLK is 120 MHz ! */
ldr r0, =CLKDIVN
mov r1, #3
str r1, [r0]
#endif /* CONFIG_S3C2440 */
开发板文件修改：
host@debian:~/soft/mini2440/u-boot-2011.03$ vim board/friendlyarm/mini2440/mini2440.c
#define FCLK_SPEED
#elif FCLK_SPEED==1 /* Fout = 202.8MHz */
#define M_MDIV 0xA1
#define M_PDIV 0x3
#define M_SDIV 0x1
#elif FCLK_SPEED==2 /* Fout = 405MHz */
#define M_MDIV 0x7F
#define M_PDIV 0x2
#define M_SDIV 0x1
#endif
#define USB_CLOCK
#elif USB_CLOCK==1
#define U_M_MDIV 0x48
#define U_M_PDIV 0x3
#define U_M_SDIV 0x2
#elif USB_CLOCK==2 /* Fout = 48MHz */
#define U_M_MDIV 0x38
#define U_M_PDIV 0x2
#define U_M_SDIV 0x2
#endif
int board_init (void)
{
......
gd->bd->bi_arch_number = MACH_TYPE_MINI2440;
......
}
int dram_init (void)
{
......
gd->ram_size = PHYS_SDRAM_1_SIZE;
return 0;
}
然后执行编译：
make
然后根据《openocd+jlink为mini2440调试u-boot》配置好openocd，然后在一个控制台下执行下面命令：
sudo openocd -f interface/jlink.cfg -f board/mini2440.cfg
同时打开一个控制台，查看串口信息：
sudo minicom
在另一个控制台下执行下面的命令：
telnet localhost
halt
init_2440
load_image /home/host/soft/mini2440/u-boot-2011.03/u-boot.bin 0x33f80000 bin
resume 0x33f80000
其中/home/host/soft/mini2440/u-boot-2011.03/u-boot.bin是我的uboot存放路径，根据自己的需要配置成自己电脑上的路径即可。
这时候在串口下会显示下面的信息：
U-Boot 2011.03--g9224c05-dirty (Jun - ::) DRAM: MiB
Flash: KiB
*** Warning - bad CRC, using default environment In: serial
Out: serial
Err: serial
Net: CS8900-
MINI2440 #
移植(三）添加对dm9000的支持：
删除下面代码：
#define CONFIG_CS8900 /* we have a CS8900 on-board */
#define CONFIG_CS8900_BASE 0x19000300
#define CONFIG_CS8900_BUS16 /* the Linux driver does accesses as shorts */
#define CONFIG_NETMASK 255.255.255.0
#define CONFIG_IPADDR 10.0.0.110
#define CONFIG_SERVERIP 10.0.0.1
添加新代码：
#define CONFIG_CMD_NET
#define CONFIG_DRIVER_DM9000 1
#define CONFIG_DM9000_NO_SROM 1
#define CONFIG_DM9000_BASE 0x20000300
#define DM9000_IO CONFIG_DM9000_BASE
#define DM9000_DATA (CONFIG_DM9000_BASE + 4)
#define CONFIG_CMD_PING
#define CONFIG_ETHADDR 08:00:3e:26:0a:5b
#define CONFIG_NETMASK 255.255.255.0
#define CONFIG_IPADDR 192.168.211.25
#define CONFIG_SERVERIP 192.168.211.2
host@debian:~/soft/mini2440/u-boot-2011.03$ vim board/friendlyarm/mini2440/mini2440.c
在board_eth_init函数中返回语句前添加代码：
#ifdef CONFIG_DRIVER_DM9000
rc = dm9000_initialize(bis);
#endif
host@debian:~/soft/mini2440/u-boot-2011.03$ vim arch/arm/lib/eabi_compat.c
修改如下代码：
int raise (int signum)
{
#ifdef CONFIG_MINI2440
printf("raise: Signal # %d caught\n", signum);
#endif
return 0;
}
此时再次进行编译，然后按照上面步骤烧写到mini2440,控制台可以得到如下信息：
U-Boot 2011.03--g5ad0f7d-dirty (Jun - ::) DRAM: MiB
Flash: KiB
*** Warning - bad CRC, using default environment In: serial
Out: serial
Err: serial
Net: dm9000
MINI2440 # ping 192.168.211.2
dm9000 i/o: 0x20000300, id: 0x90000a46
DM9000: running in bit mode
MAC: ::3e::0a:5b
could not establish link
Using dm9000 device
然后就冻结在这个地方 。
修改drivers/net/dm9000.c
#ifndef CONFIG_MINI2440
i = 0;
while (!(phy_read(1) & 0x20)) { /* autonegation complete bit */
udelay(1000);
i++;
if (i == 10000) {
printf("could not establish link\n");
return 0;
}
}
#endif
static void dm9000_halt(struct eth_device *netdev)
{
DM9000_DBG("%s\n", __func__);
#ifndef CONFIG_MINI2440
/* RESET devie */
phy_write(0, 0x8000); /* PHY RESET */
DM9000_iow(DM9000_GPR, 0x01); /* Power-Down PHY */
DM9000_iow(DM9000_IMR, 0x80); /* Disable all interrupt */
DM9000_iow(DM9000_RCR, 0x00); /* Disable RX */
#endif
}
然后按照上面步骤重新编译并将生成u-boot加载到mini2440的内存启动，执行ping 192.168.211.2。
但是第一次执行ping仍然是停留很久，我就把命令取消掉（ctrl+c)，然后重新执行ping 192.168.211.2，这次得到下面信息：
MINI2440 # ping 192.168.211.2
dm9000 i/o: 0x20000300, id: 0x90000a46
DM9000: running in bit mode
MAC: ::3e::0a:5b
operating at unknown: mode
Using dm9000 device
host 192.168.211.2 is alive
好像很多人也遇到过类似bug，等到后面再来解决这个问题。
移植（四）添加对内核启动的支持：
host@debian:~/soft/mini2440/u-boot-2011.03$ vim include/configs/mini2440.h
添加四行代码：
#define CONFIG_SETUP_MEMORY_TAGS 1
#define CONFIG_INITRD_TAG 1
#define CONFIG_CMDLINE_TAG 1
#define CONFIG_BOOTARGS "noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0"
重新编译uboot,并按照上面的步骤加载到mini2440内存并启动。
将mini2440光盘内核源代码编译成uImage(make ARCH=arm uImage)，并拷贝到tftp文件夹（tftp配置可以参考我的博文《debian7配置》）：
host@debian:~/soft/mini2440/linux-2.6.32.2$ make ARCH=arm uImage
host@debian:~/soft/mini2440/linux-2.6.32.2$ cp arch/arm/boot/uImage ~/nfs/tftp/
host@debian:~/soft/mini2440/linux-2.6.32.2$ sudo /etc/init.d/tftpd-hpa restart
然后在uboot下执行命令：
MINI2440 # tftp uImage
dm9000 i/o: 0x20000300, id: 0x90000a46
DM9000: running in bit mode
MAC: ::3e::0a:5b
operating at unknown: mode

可惜，执行到"Starting kernel"程序就不再继续向下执行。
之后，我参考了文章 《Linux 内核 Starting kernel ... 串口无输出问题归纳总结》，逐步进行排查，但仍然到"Starting kernel"就停下来了。
然后我参考了文章《Starting kernel ... 内核启动停止问题》，知道了由于uImage在zImage前加载了0x40个字节的文件头，所以实际用tftp加载的地址应该是0x30007fc0，然后再用bootm启动就可以了。
uboot输出信息如下：

信息最后内核挂掉是因为我在之前将nand flash全部擦除，所以nand flash中没有任何文件系统，也不存在/linuxrc文件，从而导致系统崩溃。
现在我关心的是uboot,所以这个问题暂时不管它，不过可以考虑在uboot中添加nfs命令后用nfs启动跟文件系统。
