Subject: [U-Boot-Users] Bug in cmd_bootm.c (byteorder)
Date: Fri, 10 Jun 2005 13:43:53 +0200	[thread overview]
Message-ID: <42A97CF9.4000800@imc-berlin.de> (raw)

Hi there,

IIUC then numbers in image headers (image_header_t) are stored in network 
byteorder. So when manipulating image headers on the target (i.e. 
overwriting ih_load) this has to be done in network byteorder.

I noticed a problem when passing a second argument to bootm

#> bootm 20500000 20400000

on an ARM platform.

The data from the my "ARM U-Boot Standalone Program (uncompressed)" was 
wrongly copied to 0x00004020!

So I suggest the following buxfix:
