Image Recevier

This is a very minimal chain loader for different architectures. It loads an image through serial line, and then passes control. It was inspired by mrvn's raspbootin, which I later ported to AArch64. This loader supports chain loader mode (that is, the image is loaded to the same address as if it were loaded by the original firmware). Unlike mrvn's version this loader is able to load not only raw images, but ELF binaries as well, which makes development easier.

The ELF files will be loaded as-is, just like the raw images. Their program header won't be parsed, except for the entry point. To get it work, you should use a linker script that includes the file headers and program headers in the text segment, otherwise it should be the same as for the raw image's script.

For sending the images, you can use mrvn's original raspbootcom command line tool, but if you have a non-Linux PC or if you just prefer windowed applications with a GUI, then I would recommend USBImager (available for Windows, MacOSX and Linux) with the -S flag instead.

You can find the chain loader implementations in their respective directories. All licensed under MIT.
