[U-Boot-Users] A question of tftpboot

[Frank Young]

Hello,

I am using tftpboot to download the uImage. But I found if I use
tftpboot 10000 uImage
The image can be downloaded with no problem. But if I use
tftpboot 1000 uImage
Then it shows me execeptions as below:

********************************************************************
=> tftp 1000 uImage-uncomp
ENET Speed is 100 Mbps - HALF duplex connection
TFTP from server 138.31.3.162; our IP address is 138.31.3.77

*****************************************************************


I checked the document but nothing mentioned about the load address of 
tftpboot. My question is, why I can download the image to 10000 while 
downloading to 1000 doesn't work?

Thanks,
Frank
