I just crush my ws100 p4 last night, when I telneted and tried to use tShell command.I remembered I pressed CTRL+X,C,H,F,G,S,and so on.I found the ws100 reboot and stay flashing on CH3.I could ping its IP,but can not connect.
I think I destroy the BOOT flash.now I wonder is it possible to upgrade the FLASH through serial port.
