Re: [rtl] Cannot get data from FIFO on RT-Linux

["Donald Radke" <radked@sympatico.ca>]

Just a couple of suggestions:

1.) M8255.c
        - move #define myfifo 0 & #define size 8192 somewhere outside of
           the function  (this will make it global to all functions within
this code)
           place just under your #include statements
        - change the word size to something more meaningful like fifo_size
        - change rtf_put ( 1, ... ); to rtf_put ( my_fifo, ...); once you
move the #define statement


See if that helps.  I myself am trying to learn how to use RT-Linux with
irq's.  I have gotten data to go from rtl -> linux -> rtl using the
scheduler but not having to much luck with interrupts.

Good Luck...
