HOWTO -- Upgrade the kernel of IP04?

In the previous version of IP04, the kernel is not the BAPS kernel, it will be not convenient
for the software upgrade (via IPKG) in future. We can use the RS232 console port to upgrade
the kernel to a BAPS base kernel.
1/ Download the latest kernel from http://www.atcom.cn/down/uimage_r2.zip. set up a TFTP
server and put the kernel on the TFTP server boot.
2/ Connect the RS232 console port to the IP04, there is a console port module ship together
with the IP04. Connect the console port to the ip04 as below picture:
Running the Hyper Terminal or Minicom in your computer to connect the IP04, the setting of the
console port should be:
Bits per second to 115200;
Data bits : 8
Parity: None
Stop bits: 1
Flow control: None
Power on the IP04 and stop the boot process at the u-boot prompt.
Now we are going to write the new uImage to flash. your:mac:address can be found using *print*
at the u-boot prompt.
3/ NOTE: Do not cut/paste the steps below into your serial terminal program, as they often cannot
respond fast enough and lose characters. Type each line carefully by hand.
