Re: [Xenomai-help] rt_task crash kernel

The timer is ticking but stops after some times

I have enabled all debug options in menuconfig but no message is printed
before the crash.

I try to patch new kernel with 2.6.20-arm-1.7-02 patch but is the same.

 

For the 2.6.15 kernel I hadn’t eabi toolchain and the kernel was not
compiled with eabi. 

For 2.6.20 kernel I have an eabi toolchain and the kernel is compiled with
eabi. 

 

In yours PXA270 board 2.6.20 kernel with xenomai 2.3.4 works?

 

Thank’s

Continuously, or does it stop ? If the timer is still ticking, it is

surprising that latency does not print anything. If the timer stops,

then we have a problem. You may also want to enable all Xenomai/I-pipe

debugging options in order to see if it prints something before

locking up.

But for the 2.6.15, you had no EABI, have you tried compiling the

v2.3.4 without EABI ? Another thing that you could try is to compile

v2.3.4 with the patch

http://download.gna.org/adeos/patches/v2.6/arm/older/adeos-ipipe-2.6.20-arm-
1.7-02.patch.

 

This patch was the last patch before reworking the tsc emulation,

knowing whether it works could help find what part of the patch is

causing the issue you observe.
