John,

When Eric Norum was here he created a script to handle this issue by

setting some timeouts.

"ucSend.sh"
====================================================
#!/bin/sh

TARGET=${COLDFIRE_TARGET_IP_ADDRESS:-xxx.xxx.xxx.xxx}

case "$#" in
    1)  ;;
    *)  echo "Usage: $0 executable_image" >&2 ; exit 1 ;;
esac
if [ \! -r "$1" ]
then
    echo "$0: $1 does not exist or is not readable" >&2
    exit 1
fi
case "$1" in
    */*)    cd `dirname "$1"` ; f=`basename "$1"` ;;
    *)      f="$1" ;;
esac
exec expect -c "set timeout 900"                   \
            -c "spawn tftp"                                      \
            -c "expect \">\""                                    \
            -c "send \"rexmt 1\r\""                           \
            -c "expect \">\""                                     \
            -c "send \"timeout 900\r\""                    \
            -c "expect \">\""                                      \
            -c "send \"binary\r\""                               \
            -c "expect \">\""                                       \
            -c "send \"connect ${TARGET}\r\""       \
            -c "expect \">\""                                       \
            -c "send \"put $f\r\""                                \
            -c "expect \">\""                                      \

================================================
Just set xxx.xxx.xxx.xxx to your Coldfire IP.

Works well for us, may not speed things up, but it does help complete

the transfer.

Hello All,

I have just built EPICS base and an example IOC for an RTEMS-uC5252

target (EPICS R3.14.11, RTEMS 3.9.3), which I can say went swimmingly

well. However tftp problems are sucking all the fun out of it. The

Arcturus uCDimm comes with a TFTP server which I am using with a

255.255.0.0 netmask. File transfer takes forever and usually ends in a

time-out error. We have some evidence that things work much better on

a subnet with a 255.255.255.0 mask. Can anyone shed light on any of this?
