AT91SAM9263ek使用設備樹啓動Linux失敗

我在啓動Linux 3.16.1時遇到問題。我使用at91sam9263_defconfig編譯了來自http://www.kernel.org的源代碼。AT91SAM9263ek使用設備樹啓動Linux失敗

我已經在引導選項中添加了扁平設備樹支持。在此（http://www.slideshare.net/softpapa/devi ... ux-8930303）演示文稿中建議的後續提示可打開/ proc中的支持設備樹，但我沒有在menuconfig中提供該選項。

我有支持設備樹的U-Boot bootloader版本2014.10rc2。我從附帶的內核腳本DTB產生：使at91sam9263ek.dtb

，現在我收到此錯誤：

解決方案：加入這一行的.config： CONFIG_MACH_AT91SAM9_DT = Y

根據內核版本和配置的不同，有多種方法可以做到這一點。這是一個修復。 – 2014-09-25 17:59:46

直接編輯.config文件是皺眉。使用'make menuconfig'。 – sawdust 2014-09-25 18:08:45
