Fixing my PM3 with OpenOCD & Olimex

I thought I'd share this to help others save time when they brick their PM3.

So, on an Ubuntu 12.04 LTS box, I installed OpenOCD using apt-get. My config for use with OpenOCD contained only the following lines:

        source [find interface/olimex-arm-usb-ocd.cfg]
        source [find target/at91sam7x256.cfg]
        adapter_khz 6000
        telnet_port 4444

I used an Olimex ARM-USB-OCD JTAG dongle, which looks like this:

After that I then followed the instructions in this post (all credit to the original poster):

Specifically the following lines:

$ telnet localhost 4444
