Thanks for the reply, I am not really want to support the TCP/IP , Wnat I do is to add the wireless network card to uboot then I can load OS firmware from another computer(maybe through tftp wlan)
Re-read Wolfgang's response, he gave you the recommended solution:
Don't waste your time. Use U-Boot to boot asmall configuration of Linux with WLAN support included, and use this to do what you want to do.
Boot your board with U-Boot, and have it run a stripped-down version of Linux that understands how to run your wireless card. Then use Linux to tftp your OS and then jump into the tftp'd version, eg. Google kexec.
Cheers, Dave
