[U-Boot-Users] problem when running the bootm command

[Erez Koelewyn]

Hi,

I am using the M5282EVB configuration. I have come across the
following problem: I load a compressed linux image into address 400000
(I leave enough
 room for it to be decompressed at address 100000).
 I then run -> bootm 400000
 This works fine (the image is decompressed at address 100000 and runs
correctly).

 Now I reset the board, download the compressed image again (using
 iminfo to very it's header is there and correct) and again I run ->
 bootm 400000

 This time I get an exception (this happens consistently until I
 program U-Boot again into FLASH, at which time I can again use bootm
 successfully only once):

 -> bootm 400000
 ## Booting image at 00400000 ...
   Image Name:
   Image Type:   M68K Linux Standalone Program (gzip compressed)
   Data Size:    1249874 Bytes =  1.2 MB

   Entry Point:  00100000

 *** Please Reset Board! ***

The problem cannot e related to overwriting critical areas in RAM
because I don't overwrite U-Boot's region or the region where I store
the packaged image.

Did anyone come across this problem

 Thanks,
