how can i change u-boot load address?

[bharath]

Hi,
 
I have built uImage using Genode OS Framework for IMX6 Sabre SDBoard. I am 
getting error as cannot get kernel image.
 
My built uImage is 7858662 Bytes =  7.5 MB
 
I used following commands to flash u-boot and uImage respectively (It is a 
16GB microsdcard)
 
$sudo dd if=u-Boot-mx6q-sabresd-no-padding.bin of=/dev/sdc bs=512 seek=2 
conv=fsync
$sudo dd if=uImage of=/dev/* bs=512 seek=2048 conv=fsync
 
When I inserted the SDCard to the board and tried to boot, it is giving the 
following error:
 
## Booting kernel from Legacy Image at 10800000 ...
 
   Image Name:  
 
   Image Type:   ARM Linux Kernel Image (gzip compressed)
 
   Data Size:    7858662 Bytes =  7.5 MB
 
   Load Address: 10001000
 
   Entry Point:  10001000
 
   Verifying Checksum ... Bad Data CRC
 
ERROR: can't get kernel image!

So, I thought of of changing please try Load Address: 10800000 as per this 
post.
