How to erase the application memory in EM1000-TEV

Hi,

I used EM1000-TEV development system.

The problem is

1) The device firmware is uploading properly through serial port. But the device reboot suddenly,by not allowing the program to upload via network.

2)Even in the device Explorer window,the device is not listed,this is because of frequent rebooting of the device.

3) The frequent reboot occurs because " sub on_pat( ) sys.reboot end sub" is included as shown below:

sub on_sys_init

dim sp as string

io.num=PL_IO_NUM_1
io.enabled=YES

ser.num=1
ser.rxbuffrq(4) 'we ask for 4*256-16=1008 bytes for the RX buffer of ser 1
ser.txbuffrq(4) 'we ask for 4*256-16=1008 bytes for the TX buffer of ser 1
net.ip = "192.168.1.93" '' set IP address << YOU MIGHT NEED TO CHANGE

sock.num = 0
sock.rxbuffrq(4)
sock.txbuffrq(4)
sock.varbuffrq(2)

sock.protocol=PL_SOCK_PROTOCOL_TCP
sock.inconmode=PL_SOCK_INCONMODE_ANY_IP_ANY_PORT
sock.httpportlist="80"

sys.buffalloc

ser.num=1
ser.enabled=YES 'The serial port is now ON!
pat.play("G-G-G_",NO)

end sub

// Some other code removed here........

sub on_pat()
sys.reboot
end sub

4)Because of this code, every time the device reboots and initializes and again reboots which is occurring continuously.Hence not allowing to upload the other program through the network.

5)Also suggest me, whether it is possible to upload the program through serial port.
So kindly suggest me the solution for these problems.
