Gabor,
Thank you very much for your help.
I got initiate two periodic tasks using a comand passed trough a fifo (from
a linux task) but it's happening something strange. When i write to the
fifo in my linux task the return value is negative (like the task couldn't
have wrote correctly to the fifo) but when i test in my rt-linux module if
the commands were received they are there (with the right values!) the same
occurs when i test if my peridic task was initiliazed (in rt module) the
return vale is negative but the tasks are initialized. The program seems
works well but i'd like to understand better how rt-linux works so you or
somebody else has some idea why this occurs?
Thanks,
Daniela.
