linux高手帮忙看下怎样进入bootloader（IPTV）
今天从新焊了快232转TTL线终于能在超级终端打印启动信息了！可是始终不知道怎样进入bootloader？？？？？？？？？？？？？？
IPTV是中兴B600V4机顶盒 CPU采用 ST的 STi5202，有 128M RAM，
16M Flash
一下是启动信息

我是这样的，一开机我就不停的敲击键盘只是始终进不去！我也纳闷了，是我频率慢了还是方法不对 Linux起来后你敲键盘有反应吗？ 如果Linux起来后，敲击按键看可否进入console，如果没有反应，测试一下看看TX信号线，是否有信号，我怀疑是你的那个TX没有接好？无法发送按键到串口中？

有啊！就是进去不了uboot 可能是特定的键的，不过很少有工程师这么变态的，因为特定的键容易出问题。 NM2012 发表于 2013-1-21 16:37 static/image/common/back.gif

估计U-Boot里面 CONFIG_AUTOBOOT_KEYED这个宏打开了。。。楼主楼主可以试下：开机的时候，单独敲键盘的每一个按键，多试几次。在u-boot打开这个宏之后，只会在特定的键按下后才会中断u-boot，但是只能是单独按键，u-boot默认不支持组合键。 USACH 发表于 2013-1-21 16:42 static/image/common/back.gif

以前做过一款产品，工控的。u-boot中断后会要求输入用户名和密码，成功后可以修改密码，密码和用户名做MD5加密，然后直接写入flash。
找到一个类似于这个的产品。
