我在启动Linux 3.16.1时遇到问题。我已经使用at91sam9263_defconfig从http://www.kernel.org编译了源代码。
我在Boot选项中添加了Flattened Device Tree支持。 在此(http://www.slideshare.net/softpapa/devi ... ux-8930303)演示文稿中建议按照提示启用/ proc中的支持设备树,但我在menuconfig中没有该选项。
我有支持设备树的U-Boot bootloader版本2014.10rc2。 我从内核附带的脚本生成了dtb: 制作at91sam9263ek.dtb
现在我收到了这个错误:

解决方案: 将此行添加到.config: CONFIG_MACH_AT91SAM9_DT = Y
答案 1 :(得分:0)
使用设备树时此板的正确配置是at91_dt_defconfig。
但是,我很惊讶地看到有人试图使用这样的旧内核。上游完全支持此板。为什么不使用v5.3?如果这不起作用,请报告任何错误,我们将很乐意帮助纠正它们。
