  • Idea is to compile applications into an .elf, which can at runtime be replaced, seperate from RIOT.
  • Currently, loading of .elf files has been tested for samr21.
  • Relocation is a bit messy as ld doesn't generate correct code on platforms which do not support thumb-2 instruction set (https://sourceware.org/bugzilla/show_bug.cgi?id=16017)
  • Test shows a simple externally compiled application (in app/) and a boilerplate RIOT application launching that application.
  • Currently, the entry point of the to-be-loaded application has to be hardcoded into the RIOT boilerplate code
    (offset added there is the address of the function in app.elf + 1 )

This sounds pretty interesting. Are you still working on it? I'd like to get over-the-air ELF loading working for my application.

I think we can close as memo, but if someone is willing to work on this soonish we would be more than happy.

I'd really love to work in this, but as is not an easy task, I must forget for now. I will reopen when the time comes.
