first of all: Thanks to Eric Norum for the termios support in RTEMS
(and for KA9Q aswell!).
Now the bad news :-<
While implementing/testing the console/termios support for
PPC403 in RTEMS-4.0.0-beta3, I am stuck at a certain location in
During "rtems_termios_initialize", the main control data structure
"*tty" is allocated using malloc(). (Note, that malloc does not clear
the allocated memory and my BSP does not clear memory during
startup). Furtheron, a lot of fields of that structure are initialized,
but the field "rawOutBufState" is not, and therefore keeps an
When "osend()" is called the first time(with the serial device driver
working in interrupt mode), termios gets stuck and will not call the
device drivers output function.
My questions now are:
- anybody already experienced this bug?
- is it a bug at all or did I do anything fundamentally wrong?
- is there already a common bugfix for that?
I don't like poking around in other people code, as long as I am not
absolutely sure, what I do...
is there a sample device driver using "termios" together with
XON/XOFF support? I found some definitions for XON/XOFF, but as
far as I understand, termios will NOT manage that (up to now :->?)
and I will need XON/XOFF for my application...
