Hi Dan:

Thanks for your advice.
The bootloader that I am using with vxWorks uses FTP but not TFTP.
And I don't have the source code of that bootloader. I think there
are maybe some problems to use it download and boot linux. So I hope
to find a TFTP source code and program a bootloader by myself.
Of course, if anybody has a presented bootloader source code,
that's great.
