about uImage-DENX-v2.6.14 config

[zhangwei zhang]

Hello, I have a problem when using linux-2.6.14(download from
ftp.denx.de) for RTAI on ppc440EP. I use the ELDK4.1 and when boot the
uImage I compiled , I always have the problem as following:

## Booting image at 00500000 ...
   Image Name:   Linux-2.6.14
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
   Data Size:    1155686 Bytes =  1.1 MB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK

then it stopped . I am afraid that maybe the problem comes from the
config. I have ever use the uImage-DENX-v2.6.14 you offered in
ftp.denx.de/pub/linux/amcc/image/yosemite/ and it works. So can you
send me a config file for 2.6.14 to me? Thank you.

Best wishes
kyla

RTAI on PPC? I thought RTAI was dead for anything other than X86.

And 2.6.14 is quite old. I suggest you use a newer binary version or compile a 
the image from the current kernel source.

Please don't stick with 2.6.14. Download the current kernel:

http://www.denx.de/cgi-bin/gitweb.cgi?p=linux-2.6-denx.git;a=summary

and there you will find the .config for the Yosemite 
(arch/ppc/configs/yosemite_defconfig).

Best regards,
Stefan

Stefan is right.

RTAI is dead.

You should use Xenomai instead.

He is reight again. Pleas euse a current kernel version from our git
repository; Xenomai should support this directly.

Or rt-preempt of course, which is the mainline way of doing realtime.
