[ECOS] need the correct template & packages for ppp

["shobhit saxena" <shobhit dot sahai at gmail dot com>]

hello everyone,
                    i am working on arm e7t board using ecos tool.I
wanna  run the following program "windows_telnet".The problem is when
i take the "net template" & add "ppp support" to the ecos options,it
successfully builds.Then i tried to make this program but it shows
error  " windows_telnet section .bss is not within region ram".i know
that the executable is more than the size of RAM in the board(512 kb).

CAN ANYONE SUGGEST ME A COFIGURATION ON THE ECOS TOOL SO THAT PPP
& TELNET BOTH WORK WITHOUT THE ABOVE ERROR.
