use xilinx gpio from linux on a ppc405

Hi

I installed (with some help of this mailinglist) a Linux (Kernel 2.6.23 from xilinx) on a ppc405 of a Virtex 2 PRO on a XUPV2P. Then I installed Xenomai. Now I want to control some devices from the Board, so I thought first I try to turn the LEDs on and of. I enabled the LEDs in my Design without interrupt and also compiled the Kernel with Xilinx OPG GPIO support. But I don't know realy how to go on. I found only 2 pages in the internet which gave me a bit of information, but nothing helped me.
Can Anyone explain me what I have to do, or send me a link to a page where it is explained?

The 2 pages I found:

Hi Jens

Thanks for your fast answer.
I have some questions befor I try it out:
1. Can I proof, if my gpio is correctly connected with my design or should I try it to proof it?
2. Is the code you send c? If yes, do I need any specific libaries? Then I crosscompile it, put it on my Board and it should work?
3. In edk I saw This at the 4 LEDs:
Base Adress: 0x40000000
High Adress: 0x4000ffff
How would it be for my case? Something like this:

char *mapped_address = ioremap(0x40000000, 0xffff);
writeb(0xffff, mapped_address);
iounmap(mapped_address);

I don't understand why the there are so many steps between the base and the high adress.

Thanks and Greez
Joachim

needhelp to install linux 2.6 on ppc405 of a virtex II pro

Hi
I want to install linux 2.6 on a ppc405 of a virtex II pro, and then patch it with rtai or xenomai. Is there some tutorial explaining the installation procedure (where to find sources, drivers etc).
I have found this link: http://users.telenet.be/steven.kauffmann/installation/index.htm 
but it concerns linux 2.4;
Can anyone help me to find useful links or documents to install the 2.6 kernel whith a real time extension?
Thanks

We don't directly support the V2Pro, but we do support the Virtex 4
which also uses the ppc405 in the Xilinx GIT Tree.

git://git.xilinx.com
http://git.xilinx.com

You should make sure that you use arch/powerpc rather than arch/ppc
which many older web sites have tutorials about. Arch/ppc is not longer
supported.

You can find more information about this at http://xilinx.wikidot.com

This information assumes you already know Xilinx products and is not a
tutorial on all Xilinx products.  It also assumes you know Linux so it
is really the Xilinx unique aspects of the kernel/BSP.

We've now created a forum for Embedded Linux at Xilinx at the following
location.

http://forums.xilinx.com

Thanks,
John

Hi,
I have installed linux 2.6 on the xupv2p board. I have uart, ethernet, but sysace device is not working.
I have seen in this forum that other persons have the problem.
Could you tell me if you have sysace driver working?
Also I want to install xenomai, but the problem is that linux from denx tree does not support opb_emac ethernet
driver. I need Ethernet because I use nfs to access the root file system.
So another question is:
when you installed xenomai, where was the rfs? and did you used Ethernet driver?

Thanks

Re: use xilinx gpio from linux on a ppc405

Hi,

This is interesting...

I have the sysace working but the ethernet not.

Just an idea:
For the sysace driver in the 2.6 kernel the old device file
entries don't work anymore.

Do you have the correct device nodes in /dev? You can create those
nodes with the following commands:

# mknod -m 660 xsa b 254 0
# mknod -m 660 xsa1 b 254 1
# mknod -m 660 xsa2 b 254 2
# mknod -m 660 xsa3 b 254 3


Concerning the ethernet...:  ;-)
Which IP Type do you have for the Ethernet_MAC? Mine is
xps_ethernetlite but I can't find a linux driver which seems to
work with this one.

regards,
Jan

Re: use xilinx gpio from linux on a ppc405

Hi Jan,
I used EDK 9.1 and I have the opb_emac ethernet controller.
I selected Xilinx 10/100 opb emac support in linux 2.6 configuration (device drivers/ Network device support/ Ethernet (10 or 100Mbit) ).
Concerning sysace, you have downloaded linux 2.6 from denx or xilinx tree?
I will try creating xsa nodes . Hope that it will work.
Thanks
Xavier

Hi,

This is interesting...

I have the sysace working but the ethernet not.

Just an idea:
For the sysace driver in the 2.6 kernel the old device file
entries don't work anymore.

Do you have the correct device nodes in /dev? You can create those
nodes with the following commands:

# mknod -m 660 xsa b 254 0
# mknod -m 660 xsa1 b 254 1
# mknod -m 660 xsa2 b 254 2
# mknod -m 660 xsa3 b 254 3


Concerning the ethernet...:  ;-)
Which IP Type do you have for the Ethernet_MAC? Mine is
xps_ethernetlite but I can't find a linux driver which seems to
work with this one.

regards,
Jan

Re: use xilinx gpio from linux on a ppc405

Hi Xavier

I downloaded the linux kernel from the xilinx git archives:

git clone git://git.xilinx.com/linux-2.6-xlnx.git

In EDK 9.1 I also used the opb_emac controller. But for the fun
of it I would love to use the newer EDK 10.1 (Well, not purely
for fun. I hope to see better performance with the mpmc DDR)

But it looks like there is no chance to get my XUPV2P properly
working with EDK 10.1... Just to bad.

Yes, hopefully it will work for you.
