OK6410裸板更新程序_update

来源：互联网发布：淘宝店铺信誉度编辑：程序博客网时间：2024/06/06 03:17

我用的飞淩ok6410开发板，DNW下载程序太容易出问题了，于是买了个openjtag，买回来才发现暂不支持MLC NAND。我下决心写个有下载程序功能的裸板程序update.

再也不用忍受DNW了，并且还介绍一种SD卡下载方法。先用飞淩提供的一键烧写工具，写mmc.bin到sd卡，再把自己要下载的程序以u-boot.bin命名，也拷到sd卡，

mmc.bin会自动帮你把程序烧写到NAND,再从NAND启动就运行你的程序了。以后这片sd卡就相当于你的下载器，需要跑什么程序拷到sd卡就OK了。

具体操作过程见后面，现在开始写update程序。

系统：ubuntu 10.04.4
单板：ok6410
编译器：arm-linux-gcc-4.3.2
搭建开发环境详见ubuntu 10.04.4开发环境配置。

目标：串口输出菜单，有以下·功能供选择

即实现读写nand,通过V2.2.exe/gtkterm发送文件到内存，再写到NADN flash 0地址，以及重启update程序。

改程序主要功能是实现更新程序，以及把程序放到内存运行·。

文件boot.lds:

SECTIONS {    . = 0x57e00000;    .text : { *(.text) }        . = ALIGN(4);    .rodata : {*(.rodata*)}         . = ALIGN(4);    .data : { *(.data) }        . = ALIGN(4);    __bss_start = .;    .bss : { *(.bss)  *(COMMON) }    __bss_end = .;}

文件Makefile:

CC      = arm-linux-gccLD      = arm-linux-ld AR      = arm-linux-arOBJCOPY = arm-linux-objcopyOBJDUMP = arm-linux-objdumpCFLAGS := -Wall -O2CPPFLAGS   := -nostdinc -nostdlib -fno-builtinobjs := start.o clock.o sdram.o init.o main.oupdate.bin: $(objs)${LD} -Tboot.lds -o boot.elf $^${OBJCOPY} -O binary -S boot.elf $@${OBJDUMP} -D -m arm boot.elf > boot.dis%.o:%.c${CC} $(CPPFLAGS) $(CFLAGS) -c -o $@ $<%.o:%.S${CC} $(CPPFLAGS) $(CFLAGS) -c -o $@ $<clean:rm -f *.o *.bin *.elf *.dis

二、编译源程序

change@change:~/Si/OK6410/update$ cd /home/change/
change@change:~$ cd Si/OK6410/update/
change@change:~/Si/OK6410/update$ make clean
rm -f *.o *.bin *.elf *.dis
change@change:~/Si/OK6410/update$ make
arm-linux-gcc -nostdinc -nostdlib -fno-builtin -Wall -O2 -c -o start.o start.S
arm-linux-gcc -nostdinc -nostdlib -fno-builtin -Wall -O2 -c -o clock.o clock.S
arm-linux-gcc -nostdinc -nostdlib -fno-builtin -Wall -O2 -c -o sdram.o sdram.c

main.c: In function 'nand_read_test':
main.c:50: warning: passing argument 2 of 'nand_read' makes integer from pointer without a cast
main.c: In function 'nand_write_test':
main.c:98: warning: pointer targets in passing argument 2 of 'nand_write' differ in signedness
arm-linux-ld -Tboot.lds -o boot.elf start.o clock.o sdram.o init.o main.o
arm-linux-objcopy -O binary -S boot.elf update.bin
arm-linux-objdump -D -m arm boot.elf > boot.dis
change@change:~/Si/OK6410/update$

这都是经过修改后的最终编译结果，所以没有错误。

三、烧写、测试

用新想到的方法烧写程序，不用前面说的u-boot下载程序。先用飞淩提供的一键烧写工具，写mmc.bin到sd卡，再把上面编译生成的update.bin以u-boot.bin命名，并拷到sd卡，接着把单板拨到sd卡启动。我的OK6410在NAND启动的情况下直接把6、7拨到on就变成SD启动了。单板SD卡启动上电，串口(115200 8 n 1)输出如下:

说明u-boot烧写完毕。烧写mmc.bin的SD卡，会自动帮你把程序烧写到NAND。接着断电取下SD卡，单板拨到NAND启动，串口输出如下：

用串口工具v2.2.exe,演示update程序功能如下：

g
use V2.2.exe/gtkterm to send file

接着选择要发送的文件eg:u-boot.bin，并发送文件，发送完毕输出如下：

the first 16 bytes data:
0x15 0x00 0x00 0xEA 0x14 0xF0 0x9F 0xE5 0x14 0xF0 0x9F 0xE5 0x14 0xF0 0x9F 0xE5
Press Y to program the flash:

接着手动发送y,这里要谨慎操作，因为一旦输入y，程序就会擦除以前的程序。串口输出如下：

update program successful

the menu of the update programe:
[w] write the nand flash
[r] read the nand flash
[e] erase the nand flash
[g] get file, and write to nand flash 0 block
[x] get file to ddr(0x57e00000), run it
[s] reset the programe
Please enter the chose:

看到update program successful上面程序更新完毕。下面来验证，断电重启，串口输出如下：

说明u-boot已经下载完毕，当然以前的程序也就擦掉了。经过测试基本OK，可能还存在bug，反正人多力量大，可以提出一起解决。

刚刚新发现一问题，用飞淩提供的一键烧写工具，写mmc.bin到sd卡，再把上面编译生成的update.bin以u-boot.bin命名，并拷到sd卡，接着把单板拨到sd卡启动。出现问题

解决error found: 0010方法：

在这里http://www.pc6.com/softview/SoftView_66768.html下载Aomei Partition Assistant Professional Edition 4.0，用该分区根据将以前分区删除，然后新建分区就行了，记住只选择你的SD卡盘，不要把自己系统盘给删了，那就亏大了。重新分区后的SD卡启动如下
