Please configure your mailer correctly.  If  you  use  special  chars

Yes, we are. Some of our customers are.

Guess why it has been added to U-Boot?

Re: make: *** [u-boot] Error 139

Dear Anthony,

it has always been a good idea to read or even search (!)  a  bit  in
the mailing list archives BEFORE posting.

You should consider this, too.

The latter is the correct answer.

What a waste of effort. The very same problem has been discussed here
JUST YESTERDAY.

Linux Bring up problem

Hi All,
 I am trying to port the EP8248 Linux image (which works perfectly on the
EP8248 board) on 
 the VPN board (In house board) which is mpc8248 based board.

 I do not have any problem with the functioning of U-Boot but Linux crashes
after printing "Uncompressing Kernel ... OK"          and then it seems
that nothing is happening.
 It would be great if u could help me resolve the issue. The following 
 is how I have configured my board:

 1. The value of the IMMR in HCRW is configured to 0xF0000000 (which is same
as in the ep8248 image). The value of IMAP_ADDR in
linux/arch/ppc/platforms/ep8248.h and u-boot/include/configs/ep8248.h 
 is 0xF0000000

 2. The memory map of EP8248 board (REFERENCE BOARD) is:

============================================================================
 Memory Region            Size                              Address Range

 
============================================================================
 SDRAM                    16MByte                      0000_0000--07FF_FFFF

 
 Flash                    8MByte                       FF80_0000--FFFF_FFFF

No. This is useless. Don't ask for a  list  of  50  different  kernel
versions with 30 different versions of MTD code which are all wokring
in any combination.

Provide some useful, reproducable information yourself.

Please use some more appropriate mailing  list  then.  I  think  this
message is off topic on uclinux-dev.

Are you sure that your SDRAM is initialized correctly?

Ummmm... 32 MB of virtual memory??? I think you mixed this up.

Re: JFFS2 support - was: (no subject)

Sorry about the lack of subject. my bad. I intended to tack on the 
subject
of my prior message.

as for my question, I'll reprint my original post:

----------------------------------------
I am using the 2.4.20 kernel and U-boot version 1.1.2. It seems as
  though
  while my kernel can read the jffs2 filesystem fine. u-boot seems to
  have some
  trouble when reading (ls) of symbolic links..

  This is pretty serious since we use busybox and that makes use of lots
  of links for
  all of the common user/shell commands.

  has anyone else seen this problem? is there a patch that fixes this? Is
  it because
  the version of jffs2 that u-boot was made to work with is different
  than the one
  that I have in my 2.4.20 kernel?
--------------------------------

more specifically, I see 3 behaviors:
1) when I do "ls", and the function comes upon a symbolic link, it 
tries to follow the link. the link
name comes out fine, but the target of the link is garbage (and thus 
sometimes crashes u-boot -
likely a  buffer overrun when printing the name)
