可以在裸箱上运行OpenWrt吗？

Question

1. OpenWrt可以在裸机上运行
2. 在uboot/barebox上是否有可移植的应用程序框架？所以我的源代码是独立于低级硬件的。

Answer 1

1. 绝对有可能。我一直在使用barebox作为imx25 SoC的主要引导程序。尽管（我从来没有遇到过）公共软件包中没有光秃盒，但是您可以构建自己的“bootloader-barebox”软件包。 只要按照这些链接： https://vivekian2.wordpress.com/2007/03/28/building-your-own-package-for-openwrt/ http://prplfoundation.org/wiki/Creating_an_OpenWrt_package_for_a_web_page

2. 我不知道有关的框架，但你可能知道，你可以创建一个应用程序。 http://www.denx.de/wiki/view/DULG/UBootStandalone

这里是barebox生成文件的一个例子：
