无法使用 lp 构建 3.10 内核？

Question

能否请您提供使用 lp 编译 linux 3.10 内核的步骤。我正在将 3.10 内核移植到 arndale 板，即带有设备树的 exynos。我通过运行

创建了 defconfig

ARCH=arm scripts/kconfig/merge_config.sh arch/arm/configs/exynos_defconfig android/configs/android-base.cfg

我试着编译它。

但是编译错误如

谁能告诉我构建内核需要遵循哪些步骤？

构建内核时哪里出错了？

Answer 1

1.Take 来自基于 arm 的芯片组的工作开源 3.10 android 内核，例如来自 http://releases.linaro.org/15.01/android/vexpress-lcr

的 vexpress

2.The 上面的内核已经支持基于 exynos 的芯片组它在 arch/arm/configs/exynos_defconfig 中也有 exynos defconfig 你可以使用这个 defconfig 并在 arndale 上刷写它，内核应该启动，因为 arndale 使用基于 exynos 的仅芯片组。

3.This 内核仅支持 arndale 中使用的 SoC，即 exynos5250，您需要添加对 arndale 特定更改的支持，例如 GUI 相关更改、外设相关更改等，因为您必须从工作中获取参考arndale android 来自 http://releases.linaro.org/14.08/android/arndale 等源代码的内核，并查找为添加对 arndale 的支持所做的更改。下面是他们添加的第一个补丁，他们开始添加对 arndale

的支持

以下是最后添加的补丁

您必须研究其间的所有补丁，包括上述两个补丁并将相关更改移植到您的 3.10 内核。祝一切顺利！

解决方法是禁用 ext3：

-CONFIG_EXT3_FS=y
-# CONFIG_EXT3_DEFAULTS_TO_ORDERED is not set
