android - 为 tegra 平台启动自定义 android 镜像时出错

Question

为 tegra 平台启动自定义 android 镜像时出错

我正在尝试在 tegra 250 板上安装自定义 android 图像。

为此，我从 nv-tegra.nvidia.com 网站下载了 android 源代码并构建了一个自定义图像。

现在我正在尝试使用 nvidia 提供的闪存实用程序来闪存我们的自定义图像。

当我只是刷新 system.img 并保持内核与 nvidia 提供的内核相同时，我在启动过程中遇到以下错误。在这种情况下系统处于挂起状态并且屏幕是空白的。

当我替换内核镜像 (boot.img) 和 system.img 时，出现以下错误。在这种情况下，系统只会不断重启。

Answer 1

Android 源 http://nv-tegra.nvidia.com看起来很奇怪，大多数 android 项目都很旧， 可能他们的 android 源也不完整。我只看到示例设备和供应商项目。 最好使用基于 aosp 或 cyanogenmod tegra 的设备配置作为开发板的开始。
