Then again, I'd like to know if your FS implementation actually needs
blocking call, and in case, where is the code supposed to block. Does
barebox have some kind of support for multiple threads, or a default
event loop where background operations can be added? Or are the FS
calls non blocking?
Sorry for asking dumb questions, I am not a barebox developer and I am
just trying to figure out what is your execution model. There
certainly is a way to integrate my TFTP implementation as soon as I
realize what is your model: as for instance we have blocking POSIX
socket calls implemented with and without an OS infrastructure, and we
are able to realize blocking calls on any systems, being baremetal or
