[Ready to use by *nix users] ./flash tool

[necromant]

Okay. OpenOCD is cool, but I wanted to have a tool that could seamlessly flash evalbot with the firmware supplied as an argument. So I made use of expect. Make sure you have OpenOCD running, the fire this thing:

#In FreeBSD that's in /usr/local/bin/expect

#!/usr/bin/expect
set timeout 60
set fw [lindex $argv 0]
spawn telnet localhost 4444
expect ">"
send "reset\n"
expect ">"
send "halt\n"
expect ">"
send "flash write_image erase $fw 0\n"
expect ">"
send "reset\n"
expect ">"
send "exit\n"


Usage: ./flash filename.bin

This will reset the CPU, halt, flash the new firmware and exit. Note the the path MUST be relative to the openocd daemon or the absolute one.

And here goes obligatory dump_flash tool, in case you want to backup your stock firmware.

#!/usr/bin/expect
set timeout 60
set fw [lindex $argv 0]
spawn telnet localhost 4444
expect ">"
send "reset\n"
expect ">"
send "halt\n"
expect ">"
send "dump_image $fw 0 262144\n"
expect ">"
send "reset\n"
expect ">"
send "exit\n"


Usage: ./dump original.bin

I got something like this using -c option on openocd. Only trouble still is that I have to run it as sudo which is annoying.
