问题描述
我刚从我朋友那里借来了 cubieboard2 并试图启动它.我将电源连接到 2A USB 充电器，将 hdmi 连接到我的显示器，将键盘连接到 USB.红色(电源)灯亮起.
I just borrowed cubieboard2 from my friend and tried to boot it up. I connected power to 2A USB charger, hdmi to my display and keyboard to USB. Red (Power) light turned on.
没有 SD 卡系统从 NAND 启动，显示内核消息，但挂起
Whithout SD card system boots from NAND, kernel messages shows up, but hangs on
[ 17.000000] Mali display drivers loaded (SOMETHING LIKE THAT)
什么也没有发生，但系统正在响应，因为当我插入 SD 卡时，它显示正确的消息:
Nothing more is happening, but system is responding, because when I insert SD card it shows propper mesage:
[ 800.000000] sd card info...
NAND 上的默认系统应该是 android(我的朋友没有碰它)，但我无法获得更多内核日志
The default system on NAND should be android (my friend didnt touch it), but I'm not able to get anything more then kernel log
使用 lubuntu SD 卡 系统正常启动，但我得到的第一个图像是桌面.开机后-屏幕打开，但全黑，根本没有消息.大约 3 分钟后，桌面出现.
With lubuntu SD card system boots up properly, but the first image I get is desktop. After power on - screen turns on, but is whole black, no messages at all. After about 3 minutes desktop shows up.
使用默认的 cubieboard2 busybox 完全按照 http://www.smida.it/geekeries/cubieboard-buildroot.php - 这是最令人沮丧的部分！在我的电脑上使用虚拟gentoo机器制作图像大约需要5个小时.之后，我用我的操作系统创建了 SD 卡.当我插入 SD 卡并启动设备时 - 屏幕打开，有一些 SD 卡活动，但根本没有图像.屏幕为黑色(但已打开)，SD 活动 LED 闪烁片刻，然后……什么也没有.Num-lock 响应，按随机键 - 没有 SD 卡活动，但 alt-ctr-del 使板重新启动.
With default cubieboard2 busybox created exactly as on http://www.smida.it/geekeries/cubieboard-buildroot.php - this is the most frustrating part! It took about 5 hours to make image using virtual gentoo machine on my pc. After that i created SD card with my OS. When I inserted SD card and booted device - screen turns on, there is some SD card activity, but no image at all. Screen is black (but turned on), SD activity LED blinks for a moment and then... nothing. Num-lock responds, pressing random keys - no SD card activity, but alt-ctr-del gives board a restart.
- 如何让我的董事会正常工作?
- 有什么方法可以调试"它吗?通过连接串行接口或类似的东西?
- 我可以使用 qemu 在我的 gentoo 虚拟机上模拟"映像吗?
- 也许我在做的明显错误?
推荐答案
好的，终于有解决方案了.
Ok, finally got solution.
事实上，我的主板正在启动，一切正常.但是在 inittab 中唯一的 tty 是 ttyS0，它是串行 tty.
In fact my board was booting and everything was fine. But in inittab the only tty was ttyS0 which was serial tty.
使用/dev/tty1 添加 getty 后一切正常.
After adding getty with /dev/tty1 everything works fine.
