Hi,
Because image size no smal to download via UART
(Ehernet not have), I'm trying tuning PPP connect from host PC to uClinux
board.
I find next example:
inittab:
s3:respawn:/sbin/agetty -iLn -l /etc/ppp/nullppplogin 115200
ttyS2 vt100
/etc/ppp/nullppplogin:
#!/bin/sh
mesg n
stty -echo
while true
do
chat
-t 3600 CLIENT CLIENTSERVER
case "$?" in
0) exec /usr/sbin/pppd;;
3) continue;;
*) break;;
esac
done
/etc/ppp/options.ttyS2 :
-detach
silent
xonxoff
asyncmap
0xffffffff
local
lock
noauth
proxyarp
:192.168.5.254
lcp-echo-interval 20
lcp-echo-failure 2
I correct ttyS2 to ttyS0 Have
next result:
