Question

OpenWrt可以在裸机上运行
uboot / barebox上是否有可移植的应用程序框架？所以我的源代码与低级硬件无关。

Answer 1

绝对可能。我一直在使用裸机作为imx25 SoC的主要引导程序。公共包装中没有裸箱（我从未见过它），但你可以建立自己的＆＃34; bootloader-barebox＆＃34;包。只需点击这些链接： 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
我不确定框架，但您可能知道可以创建一个应用程序。 http://www.denx.de/wiki/view/DULG/UBootStandalone

以下是裸机的Makefile示例：

OpenWrt可以在裸机上运行吗？
