Hi,all users!
Firstly,thank u for your help!
now let's go to talk about the latest test results on my board use a rtl8019 .
i think it's necessary to show my ide first.
my board use s3c44b0 and rtl 8019as, and i port u-boot 1.1.4 to my board.as you know ,there are some problems with my rtl8019.i use a pc(runs win2k) to do the test work. Note,my pc and my board communicate by a hub.that is ,my pc and my board both plug their rj45 head in the hub .my pc's ip is,gateway: board 's ip is
i get some suggestions ,and i did some amend.as follows:
yesterday,i install a 3CDaemon(a tftp server soft) on my win2k system to start up the tftp service on my win2k system.and i install the ethereal to capture the data on the net. of course,i run the two programs on the win2k.
to test my tftp server,in the cmd command window(in win2k),i type "C:->tftp get image.bin",the result is perfert.and i found the file "image.bin" in the C: directory.
but unfortunately, when i start my board,i didn't see my board's ip list in the 3CDaemon and ethereal.(i think the ip should in the list of the two soft?).
the board's information show as follow:
