Re: PCMCIA Card, RTAI on PowerPC

In message [ref] you wrote:

Now I wanted to patch this kernel to run RTAI on the Board.

In this  case  you  should  post  your  question  /  problem  on  the
rtai@rtai.org mailing list instead.

Testing if the pach works with --dry-run I received the following:

patch --dry-run -b -z.PRE_RTAI -p1 < ../patch-denx-linux-2.4-D2002-09-26

Seems you are using the wrong kernel  source  tree;  the  patch  name
"D2002-09-26"  suggests  that  you  should use the kernel source tree
version from date 2002-09-26.

Then I read that it is necessary to download the tree with revision date
2002-09-26. I did this one and created a kernel-image without rtai
like before, and I copied it to the board and this time the following
happened:


Serial driver version 5.05a (2001-03-20) with no serial options enabled
Oops: kernel access of bad area, sig: 11
NIP: C00B91CC XER: 8000007F LR: C00BD810 SP: C0209DC0 REGS: c0209d10 TRAP:
0300

Obviously you have mis-configured your kernel. You try  to  access  a
non-existent device (standard serial port?).

What I would need is a combination of the source trees. The ideal would be
if i could patch the
kernel linux-2.4 from anonymous ftp on DENX as my PCMCIA card works with it.
Does
anyone have any suggestions what I could do to be able to patch this kernel?

Just follow the instructions in ftp://ftp.denx.de/pub/RTAI/README

Best regards,
