Recently I’ve managed to brick my sheevaplug. For those not familiar with sheevaplug, they are basically a small plug computer which is ideally suited for being a small home server. I use mine as a NAS at home.
Thankfully, it was very easy to unbrick the sheevaplug thanks to a couple of really helpful website. There is a thread on NewIT that helped me unbrick my plug.
Below is a summary of what I’ve done following the instructions from NewIT above. Basically, you need to have openocd, screen and telnet installed. I’ll be assuming you are using Ubuntu for this.
sudo apt-get install openocd screen telnet
You would need to download a temporary uboot so you can boot the sheevaplug.
Next, plug the sheevaplug in using a miniUSB data cable, and start screen
sudo screen /dev/ttyUSB0 115200
Now, start openocd
sudo openocd -f /usr/share/openocd/scripts/board/sheevaplug.cfg -s /usr/share/openocd/scripts
Then, in a new terminal, connect to openocd
telnet localhost 4444
Now, in the telnet session, run the following
reset;sheevaplug_init;load_image u-boot.elf;resume 0x00600000
Finally, you can begin reinstalling your sheevaplug through the screen.
