No, unfortunately not (yet?). Thats a wish I just have for several
years, but a dynamic linker would not work well with small scale
embedded systems, as you always have to include the symbol table into
your executables and also would have to hold a symbol table of your
libraries and operating system in flash / ram which will probably run
out of space very fast.

A good alternative would be to implement a bootloader that loads the
needed driver "application" from SD-card and then jumps to this code.
But your "driver" will always be a full Nut/OS application, which means
the each driver will be larger than needed, but on an SD-Card that would
If this is an option and you need support for implementing the
bootloader, please let me know.
