Question

首先让我告诉你我正在使用OS X 10.7.5开发MAC。我正在尝试编译Goldfish 3.4内核并在模拟器上运行它。它编译好，但是当我运行它时，模拟器打开并冻结。当我做一个“顶部”时，我可以看到模拟器像疯了一样运行，但屏幕上没有任何东西出现。这是我编译内核的方法

git clone https://android.googlesource.com/kernel/goldfish.git
git checkout -t origin/android-goldfish-3.4 -b goldfish3.4
make ARCH=arm goldfish_defconfig
make ARCH=arm SUBARCH=arm CROSS_COMPILE=/Volumes/androidSpace/android_work/prebuilts/gcc/darwin-x86/arm/arm-eabi-4.6/bin/arm-eabi-

然后我通过

运行模拟器

./emulator -debug init -kernel /Volumes/androidSpace/goldfish/goldfish/arch/arm/boot/zImage -system /Volumes/androidSpace/android_work/out/target/product/generic/system.img -ramdisk /Volumes/androidSpace/android_work/out/target/product/generic/ramdisk.img -avd firstAvd -wipe-data

以下是运行模拟器

的调试输出的最后一部分

输出只是冻结在这里。有没有人知道构建3.4金鱼内核的步骤。

Answer 1

目标“goldfish_defconfig”为ARM 926配置内核，但现在仿真器配置为在arm7架构上运行。你应该使用“goldfish_armv7_defconfig”。

按照以下步骤为模拟器构建3.4内核

git clone https://android.googlesource.com/kernel/goldfish.git
git checkout -t origin/android-goldfish-3.4 -b goldfish3.4

make ARCH=arm goldfish_armv7_defconfig
make ARCH=arm SUBARCH=arm CROSS_COMPILE=/Volumes/androidSpace/android_work/prebuilts/gcc/darwin-x86/arm/arm-eabi-4.6/bin/arm-eabi-

这应该构建一个3.4内核，你可以这样运行（我假设你的目录结构有默认的sdk ramdisk.img）

./emulator -debug init -kernel /Volumes/androidSpace/goldfish/goldfish/arch/arm/boot/zImage -system /Volumes/androidSpace/android_work/out/target/product/generic/system.img -ramdisk /Volumes/androidSpace/android_work/out/target/product/generic/ramdisk.img -avd firstAvd -wipe-data
