如何将 libtomcrypt 集成到 u-boot 中？

Question

对于一个研究项目，我需要将不同的加密函数（PRNG、SHA1、对称加密/解密）合并到 u-boot 的 MLO 部分。

我的问题：

1.) 以前有人做到过吗？

2.) 你们知道吗，考虑到 MLO 的有限大小和 libtomcrypt 的大小，这甚至是可能的吗？

3.) 除了将它们从 /usr/include/ 复制到 {u-boot-src}/include/ 的直接方法之外，有人知道解决丢失的 *.h 文件错误的优雅方法吗？

非常感谢。

Answer 1

1.) 以前有人做到过吗？

我没有。

2.) 你们知道吗，考虑到 MLO 的有限大小和 libtomcrypt 的大小，这甚至是可能的吗？

libtomcrypt 似乎几乎被遗弃了。可能有更好的选择。警告购买者。

3.) 除了将它们从 /usr/include/ 复制到 {u-boot-src}/include/ 的直接方式之外，有人知道解决丢失的 *.h 文件错误的优雅方法吗？

使用--sysroot 传递arm 头文件和库的根目录或SYSROOT。在SYSROOT下，应该有include/和lib，编译器和链接器会找到需要的头文件和库。

或者，使用-I 传递标头路径，使用-L 传递库路径。
