求助，点亮LED没有反应

chenhaiyang · 发表于 2010-7-4 12:28:47

刚刚买了QT2440，在网上找了一个点亮LED的程序，自己模仿写了一个，但是烧进去之后，没有反应。求解！谢谢了先。
代码如下：环境是ubuntu 10.04

谢谢LS的，板子是买的新的，在淘宝上面，580元的那一套。
另外：输出0的我也试过，我怀疑是不是我烧录的方式有问题？应该怎么烧呢，从nor flash启动后用哪个选项呢？我都是用A的。

回复LS，我试了，还是有问题，选择7之后，我用dnw下载，完了之后，板子就重启了。

我怀疑是不是我的板子有问题阿，可是用WINCE里面的LED测试程序，没有问题阿，都能控制。不知道怎么办了。

chenhaiyang · 发表于 2010-7-5 22:14:14

把程序再贴一遍，麻烦您再看一下。
我的操作是：
norflash 启动，选择7，提示USB已经链接，等待下载数据。
然后，sudo dnw test

然后板子重启，串口有进入了norflash启动界面。

修改后的代码:

终于点亮了，但是我却迷茫了……………………
我之前一直烧的是经过objcopy之后的纯二进制文件，一直不成功，今天我烧了.o类型的ELF格式的文件，怎么就可以了呢？裸跑程序阿，怎么烧bin不行而ELF就可以呢？希望赐教一下啊。

你把用命令7时的串口信息贴出来。

串口信息中，后面的菜单是自动出来的。。。。。。。。。。。。。。。

chenhaiyang · 发表于 2010-7-6 20:03:01

谢谢LS，其实，test，和test.bin都是一样，只不过后来我给改了一下名字而已。
另外，资料我都是再网上搜的，arm-linux-gcc
还希望LS的可以加一下我的QQ，日后希望不吝赐教。

不是啊。是 “涅磐火凤”

你修改DNW，将0x32000000改为0x30000000，然后就可以使用命令7烧写到内存中运行了。

谢谢两位了。
问题解决了，原来是我的dnw是有问题的。再写的时候有可能出现奇数字节的写的情况。这样肯定会出问题，所以我把dnw改了。这个dnw是再网上下载的。没有想到居然有问题。
把修改后的贴出来吧。这样也许对遇到同样问题的一个方便的解决方式。（修改后是按照字单位的。呵呵，没有修改驱动部分。这个是linux版本）

chenhaiyang · 发表于 2010-7-6 21:43:25

但是，至于为什么用linux下的elf的.o文件就可以执行，甚至可以从nandflash启动，这个就不得而知了。这个问题可真实郁闷了阿。呵呵。不管怎么样，问题至少是解决了。呵呵。
