DENX Software Engineering proudly announce:
On our FTP server you can find our first public release of patches
that allow the use of the Linux Real-Time extensions RTAI (Real-Time
Application Interface, Version RTAI-24.1.4) and RTLinux (Version
RTLinux-3.0) on the Embedded PowerPC Controllers of the Motorola
MPC8xx family. The patches are running and have been tested with the
Linux version 2.4.4 kernel, which is avaliable on the same FTP
server.
Rationale: Both real-time extensions of the Linux kernel (RTAI and
RTLinux) have been running on the PowerPC architecture for some time.
But so far they only supported the "bigger" CPU's. They did not run
on Embedded Controllers like the Motorola PowerQICC CPU's, which are
very attractive for embedded systems since they integrate a lot of
peripheral functions which allows for very small systems like the
half-credit-card sized TQM8xxL mini-modules. With our patches you can
run Linux applications with hard real-time requirements on such small
systems.
There are also several new features in our version of the Linux 2.4.4
kernel, like a framebuffer driver to control LCD displays on a MPC823
processor, or a new version of the MPC8xx UART driver that supports
hardware flow control on all 4 SCC ports.
