Linux for ml310

Linux for ml310

[Joachim Meyer]

Hi

I'm trying to run a Linux System on a ml310
I'm using the Kernel 2.4.26 from Bitkeeper und and EDK9.1 Sp2
I can compile my Kernel without Errors, with a Crosscompiler made by crosstools, if I don't copy the BSP files in the Kernel Directory.
If I do so, I can't compile. It aborts with the error:
serial.c:4040: error: 'XPAR_UARTNS550_0_CLOCK_FREQ_HZ' undeclared (first use in this function)
If I don't use the UART in my Kernel config I get other errors like:
adapter.c:96: error: `XPAR_XEMAC_NUM_INSTANCES' undeclared (first use in this function)
I don't really know what to do now. Where should I look for the solution?
Did I something wrong by generating the BSP or do I have to use an older version of the edk/ise?

When I was trying to find a solution I read some of the things in this mailing list, and now I'm concered about these 2 points
-Board
-Kernel Version
Is it a good idea to use the ml310?
I want a Linux, an ethernet device, a RS232 device and system-ace. Later I would try to patch the Linux with rtai for real-time-support.
I read about troubles with the ethernet device on the ml310 because of troubles with the pci bus. Would it be much easier to use an XUP-Board?
Would it be easier to use the kernel 2.6.x? Has anybody experience in running an rtai-patched Linux on an ml310 - bzw XUP Board?

Greetings & THX Joachim

Applying the BSP to the 2.4 kernel is a error prone process.  You need
to be using the *exact* version of the MontaVista kernel that EDK is
expecting, otherwise it breaks and you need to fix it up manually.
2.6 is much better and you don't need to copy over the whole BSP; just
the xparameters.h file.

I strongly recommend moving to 2.6.  I don't know if anyone has got
rtai going on it for the virtex, but your chances of getting help are
much higher because virtex 2.6 support is being actively developed.

As for the XUP board, I haven't had a chance to get mine running yet,
but I know others have had good success with it.

Cheers,
g.

Linux for ml410

[mojtaba]

Dear All,
I am trying to compile Linux 2.6.25(which I got from git.xilinx) for ML410
board and I have a problem during compilation. This is the error message:

 CC      arch/ppc/platforms/4xx/xilinx_generic_mlxxx.o
arch/ppc/platforms/4xx/xilinx_generic_mlxxx.c: In function
'virtex_device_fixup':
arch/ppc/platforms/4xx/xilinx_generic_mlxxx.c:31: error: dereferencing
pointer to incomplete type
make[1]: *** [arch/ppc/platforms/4xx/xilinx_generic_mlxxx.o] Error 1
make: *** [arch/ppc/platforms/4xx] Error 2

it seems that xlltemac_platform_data structure is not recognized by the
compiler so it cannot dereference it. I do not know what this structure is
and where it has been defined. I really appreciate if you can help me.
Best regards,
Mojtaba

I'm guessing you used the standard BSP generation process, which
overwrites files in the kernel.  Instead, you should generate the BSP
into a dummy directory and copy only the xparameters_*.h file over to
the kernel.  This is all that is needed in the git tree, since it
contains all of the required drivers.

Re: Linux for ml310

Hi 

I switched "Xilinx uartlite serieal port support" and "Support for console on Xilinxuartlite serialport" on and "8250/16550 and compatible serial support" off, in the kernel config.
Then I removed the things I added in the xparameters.h and compiled successfully.
But I have yet a few Questions:

- What would you recommend to use? UART-Lite or a 16550 serial port. Can I get a console running on the RS232 Port of the Board with both possibilities?

- Can you recommend anything for my next steps to get an running linux (rootfs usw.)? So far I oriented myself on the Klingauf page, but I think it is perhaps not the best one because its too old and some things will probably not work the way he did it anymore.

Greez & Thanks
Joachim

if you don't need to change the baud rate at runtime then use the uartlite.

Console works on both.

Use either ELDK or buildroot.  Personally, I'd like to be using
OpenEmbedded, but I haven't been successful with that yet.

Hi, I was reading this post and a question came to my mind.

When I try to compile, did I have to copy the EDK driver folder to my Xilinx
2.6 kernel tree and run the cow.tcl script generated by EDK?? Or this is
unnecesay??

RE: Linux for ml310

[Stephen Neuendorffer]

If you are using the secretlab.ca or git.xilinx.com trees, then you
should *not* follow the normal BSP generation process.  You need to
generate the BSP in a dummy location and then copy only the
xparameters_*.h file over the appropriate one in
arch/ppc/platforms/4xx/xparameters and make menuconfig.
