Linux booting problem on Xilinx ppc

Linux booting problem on Xilinx ppc

[Junqiang Hu]

Dear friends,

   I'm trying to run Linux in AvNet (Memec) Xilinx-XC2VP50-EVKT-FF1152
 board.  The Linux version I'm using is 2.4; the cross-compiler is
gcc-4.1.0, glibc 2.3.6.  When booting the kernel, it shows:
      loaded at:     00400000 004B51E4
      board data at: 00000000 00000018
      relocated to:  0040526C 00405284
      zimage at:     00405B2B 004B177C
      avail ram:     004B6000 60000000

      Linux/PPC load: console=ttyS0,9600 root=/dev/xsysace/disc0/part3 rw
      Uncompressing Linux...done.
      Now booting the kernel

Then it hangs. First it seems to me that the "avail ram" is not correct,
since I configured only 32MB SDRAM.  Moreover, if it's first powered on, the
end address of "avail ram" would be FFD9FBED. Then I tried to investigate
the problem using xmd.  When  launched, it says:

Then after issuing "stop", it says "unable to stop processor"

I also tried kernel version 2.6.22, but the same thing happens, except that
the "avail ram" changed to 7C9E2378 and it's the same no matter first
powered on or not.

  No idea how to continue...

  Could somebody give me some help? Thanks!

I strongly recommend moving to a 2.6 kernel.  Recent mainline has
support for the Xilinx ppc built in.

(If you're using u-boot) You might have a mismatch between the board
info structure used by u-boot and the one used by Linux.

Also, you should use your debugger to inspect the __log_buf memory of
the kernel.  A common problem is the kernel starts booting, but the
console is setup incorrectly and so you see nothing.  But, you can
read the console output directly from memory if you look at the
__log_buf region (find the address in the System.map file; you might
need to subtract 0xC0000000 from the address to view the memory)

Hi Grant,

   Thank you so much for the reply!  Fortunately I got it work now -- it's
the crosstool compiler problem.  Originally I was using gcc-4.1.0, yet when
compiling kernel 2.6.22, I noticed that it says gcc-4.1.0 will miscompile
the kernel, so I changed to another version, and now I can let it go!

  Right now still not fully booted because of the SystemACE problem, or
maybe the partition is not correct.  I'm still working on it, hopefully to
get it solved soon :-)

Thanks,
-J.

RE: Linux booting problem on Xilinx ppc

[Stelios Koroneos]

We are seeing similar problems (wrong memory displayed, kernel hangup) when
compiling a 2.6.23-rc2 kernel with gcc 4.1.1 for an ml403 board.
Using gcc 3.4.4 to compile the kernel, then there is no problem (the kernel
boots)
Setting mem in the kernel config does not solve the issue.

Re: Linux booting problem on Xilinx ppc

[aauer1]

Hello

I'm also working with ML403 board from Xilinx and have the same problem as
you. The boot process stops after decompressing with the message "Now
booting the kernel". We also used gcc-4.1.0 for the cross compilation. So, I
would be glad to know, which gcc version have you used to get a working
kernel!

Thanks,
Andreas

RE: Linux booting problem on Xilinx ppc

[Koss, Mike (Mission Systems)]

In house we use the gcc 4.1.2, glibc 2.3.6 combo with success.

Hello

I'm also working with ML403 board from Xilinx and have the same problem
as you. The boot process stops after decompressing with the message "Now
booting the kernel". We also used gcc-4.1.0 for the cross compilation.
So, I would be glad to know, which gcc version have you used to get a
working kernel!

Thanks,
Andreas

First step:

Get a JTAG debugger and look at the __log_buf address.

I noticed this problem happens when on-chip memories are enabled in a design
(it is 4th page in base system builder). Try to leave them "none" for both
instruction and data.

RE: Linux booting problem on Xilinx ppc

[aauer1]

The on-chip memories are disabled. Only the BRAM is enabled. Now, we also use
the ELDK 4.1 from Denx and the included cross compiler. The result is the
same... the Kernel stops at "Now booting the kernel". Now, we also have an
USB JTAG cable. So, we can debug the memory. 
Probably, anyone has another idea.

Thanks,
Andreas

There are two common reasons for this behaviour:
1. kernel crashes before the console is configured
2. the console is not configured correctly.

In both cases; finding a way to look at __log_buf is the fastest way
to figure out what is going on.

I was able to look at the __log_buf variable with the JTAG cable. So, I
recognized that the kernel doesn't halt after the "No booting the kernel"
message. There are many output messages in the __log_buf variable until it
stops at with a "Kernel panic" because the rootfs is not found (but this is
the minor problem).
Now, I know that the kernel boots but I don't get an output with my Xilinx
UartLite module. Are there some kernel modules which must be activated?? 
Btw. I have used the Linux-2.6-virtex kernel from
http://git.secretlab.ca/git/ and another Kernel (2.6.23 from kernel.org) -
both with the same result.

Thanks a lot,
Andreas
