[Xenomai-help] migrate code from xenomai-2.3.0 to xenomai-2.3.4

[Urs Eichholzer]

Hi

Can I migrate my code from xenomai-2.3.0 to xenomai-2.3.4 without modification
on the Linux OS kernel core. Is it possible to modify and patch only the whole
xenomai source not including the Linux kernel.

Thanks!

Urs

Xenomai 2.3.0 is quite old and I recommand to  update to 2.3.5., at lreast

Ah, I see. Does the attached patch help?

As there are important bug fixes for ADEOS I-Pipe as well, you are urged
to update your Linux 2.4 kernel. Move to Xenomai 2.3.5 with the
adeos-ipipe-2.4.25-ppc-DENX-1.2-02.patch.

I'm still curious, did the patch help?
