[U-Boot] memory display question

[Steve Iribarne]

Hello List.

I have a Freescale iMX25.  Seems to work fine and I'm trying to get some 
of the security features working.

I'm currently getting an error when I try to do a secure boot (internal 
to the processor). So the next step is to verify that my u-boot image is 
loaded where I think it should be loaded (at TEXT_BASE (0x83F0_0000)).

When I do a md.w 0x83F00000 0x20 it display's all zero's which is wrong. 
  It should have my reset vector and some other things there.  The image 
header is really at offset 0x400.

So I tried md.w 0x83F00400 0x20 and still all 0's.

This makes no sense because the darn thing boots!

When I hook my Lauterbach to it and do a view memory through the JTAG 
the memory looks as I expect.  This makes complete sense because if this 
wasn't the case I wasn't sure how my system was going to boot.

Has anyone else seen something like this?  If so, could you shed some 
light on what you did to remedy the issue.

thanks.
