<TITLE>Linux 2.6 PCI Device Driver on Virtex 4</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/plain format -->
<P><FONT SIZE=2>I have spent the past few months slowly trying to get a PCI design<BR>
with Linux 2.6 on the Virtex 4. I have been able to overcome some of<BR>
the hurdles; however, I am still unable to boot up a working system.<BR>
<BR>
I am using PPC.I have implemented Xilinx's board support package including<BR>
xparameter head file, ml410 early boot files, pci support files,<BR>
Board initialization file, did board specific setup, and fixed some<BR>
bugs in its call tree.<BR>
<BR>
I have attached my booting message in this mail. As you can see, I am<BR>
stuck at "[ 11.805382] Freeing unused kernel memory: 100k init" . Usually<BR>
it's the last step before the kernel starts root file system. I am sure my ramdisk and<BR>
root file system were both working OK. My naive thought is that the kernel could not<BR>
register serial port successfully (see time stamp [ 5.965954]). As a result, ttyS0 was<BR>
not able to run and display messages after starting ramdisk.<BR>
<BR>
It's also interesting to see my ml410 board respond me with a "ml300"<BR>
id. My booting message was saying:<BR>
pci_scan: bus 0, device 8, id 030010ee<BR>
"10ee" is the vendor id for xilinx while "0300" is the device id which<BR>
I think might represent ml300. Does Xilinx forget to refresh its rom?<BR>
<BR>
<BR>
Here is my environment and tools:<BR>
-- Xilinx ML410 Rev C<BR>
-- Xilinx EDK 9.2i<BR>
-- Secret lab Linux v2.6 originally configured as platform Xilinx<BR>
ML403<BR>
<BR>
And my booting message:<BR>
