Pogoplug E02 Brick

[nguyenhunga5]

Hi every body,

First sorry because my english very bad.

I have one Pogoplug E02, but it's bricked, TTL cannot connect. I have j-link to connect with jtag, but I don't know how to connect jlink with my Pogoplug E02.

Please tell me how to connect and use openocd to restore it.
Thanks you.

I have never jtaged it myself, but this might help: viewtopic.php?f=18&t=1120
Beware the last suggestion to use kwboot does NOT work on E02

More than a year ago I bricked my Pink PogoPlug E02. I spent many weeks trying to find a solution and eventually I was able to unbrick my PogoPlug. I am sorry, but this was so long ago I don't remember the details, however, first I had to find a way to make a serial connection to the PogoPlug and I did write myself some notes that I hope will help you.

My notes talk about two cables, a PogoPlug Serial Cable and a BeagleBone USB-Serial cable, but I don't remember where I got the "PogoPlug Serial Cable". I must have modified the PogoPlug Serial Cable to work with the BeagleBone USB-Serial cable. I *think* I purchased the BeagleBone USB-Serial cable from Adafruit, but it's been so long, I'm sorry I don't remember. I have no idea where I got the PogoPlug Serial Cable, maybe eBay or maybe I made it.

Here is a link to a good article about PogoPlug serial connection:

So here are my personal notes, I hope they help you.
$this->bbcode_second_pass_quote('', 'I')f you have a bricked PogoPlug do the following.
Connect the BeagleBone USB-Serial cable to the PogoPlug Serial Cable using the following color code
PogoPlug Serial Red (ground) to BeagleBone USB-Serial Black (ground)
PogoPlug Serial Black (RxD) to BeagleBone USB-Serial Green (TxD)
PogoPlug Serial White (TxD) to BeagleBone USB-Serial White (RxD)

Plug BeagleBone USB-Serial cable into PC
Requires Prolific Drivers – BeagleBone cable uses PL-2303 XA / HXA Chip
http://www.prolific.com.tw/US/ShowProdu ... 25&pcid=41

Device Manager – Look for Prolific USB-to-Serial under Ports
Under Properties and Port Settings Tab Set:
Baud: 115200
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None

Using PuTTY, set the same settings for the Serial port (Category: Connection – Serial)
Now connect to the port (probably COM3)

Boot the PogoPlug and you should see status data in the window.

System will boot to “root” login, but the filesystem may be set to read only.
Type: df to get the file system name where / is mounted then type
mount -o remount,rw /dev/hda2 / where /dev/hda2 is the file system where / is mounted
