问题描述

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.它可以编译，但是当我运行它时，模拟器会打开并冻结.当我做顶部"时，我可以看到模拟器疯狂地运行，但屏幕上什么也没有出现.这是我编译内核的方法

First let me tell you that I am working on MAC with OS X 10.7.5. I am trying to compile Goldfish 3.4 kernel and run it on emulator. It compiles alright but when I run it the emulator opens and freezes. When I do a "top", I can see the emulator running like crazy but nothing turns up on the screen. Here is how I compiled the kernel

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

./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

这是运行模拟器后调试输出的最后一部分

Here is the last part of the debug output from running the emulator

QEMU options list:
emulator: argv[00] = "./emulator64-arm"
emulator: argv[01] = "-android-hw"
emulator: argv[02] = "/Users/deathwillarrive/.android/avd/firstAvd.avd/hardware-qemu.ini"
Concatenated QEMU options:

emulator: sent '0012host:emulator:5555' to ADB server
emulator: ping program: /Volumes/androidSpace/android_work/out/host/darwin-x86/bin/./DDSs

输出只是在这里冻结.有谁知道构建3.4金鱼内核的步骤.

The output just freezes here. Does anybody know the steps to build 3.4 goldfish kernel.

推荐答案

目标goldfish_defconfig"为 ARM 926 配置内核，但现在模拟器配置为在 armv7 架构的 cortex A8 上运行.您应该改用goldfish_armv7_defconfig".

The target "goldfish_defconfig" configures the kernel for an ARM 926 but the now the emulator is configured to run on cortex A8 which is a armv7 architecture. You should use "goldfish_armv7_defconfig" instead.

按照这些步骤为模拟器构建 3.4 内核

Follow these steps to build a 3.4 kernel for emulator

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，然后您可以像这样运行它(我假设您的目录结构具有默认的 sdk ramdisk.img)

This should build a 3.4 kernel which you can then run like this (I am assuming your directory structure has default 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

试试这个并告诉我们
