Can anyone from CE provide the pinouts for the two connectors labeled J1 and CON3 on the v2 hardware board? I would lay odds the CON3 is a serial port, I really hope so. J1 has 8 pins, that's most certainly JTAG. Thanks.

Can you post a photo of the board?

Photobucket Photobucket Photobucket Photobucket Photobucket Photobucket I measured the voltages on CON3 with a DMM and three of the pins had 3.32V and the last one was ground.

Thanks for the photos!

The connectors look a  lot like the connectors on the original board. The original board had the pin designations silk-screened for the serial console on the 4 pin connector. I'm guessingthat the pinouts are the same.

Can Cloud Engines confirm they are the same?

CON3 is a v3.3 serial port for console.  It can use the same level shifted serial ports as the v1 boards.  the Pitch of the connector is different, but the signals are the same.  Here is the signal definitions:

So if the connector pitch is different, what Molex connector do we need now to wire up the serial port? Thanks Brad!

Very cool, I'm going to order some of those right now. Thanks!

I got the connectors in. I just bought 25 of them for the price. If anyone wants a connector to make their own serial cable, just PM me with your address and I'll send one to you.

I now have the serial console wired up and working with the new Pogoplug v2. I just posted the picture of the pinout of the port. The link to the complete output is here:  http://pastebin.com/f1efc6125 .

Will I be in any danger using a U-Boot for the SheevaPlug on my PogoPlug? If they are the same hardware accept for the amount of NAND flash and a couple of peripherals, I would expect things to go okay. I plan on using the U-Boot listed here:

U-Boot Upgrade

Has anyone else attempted this yet on the Pink v2? I'm doing this because it appears that USB support in U-Boot itself is turned off. Thanks.

@sjhill
The sheevaplug u-boot is NOT compatible with the Pogoplug. The reason being the difference in RAM. I tried it on the V1 plug. After installing the sheevaplug u-boot I got a u-boot prompt but I was not able to boot a kernel because of the RAM difference.

Booting the kernel from USB is not supported in the Pogoplug u-boot.

I was able to compile the Sheevaplug uBoot 3.4.16 to work with the Pogoplug and boot the kernel from USB as described in:
http://openpogo.com/forum/viewtopic.php?id=72

I found that booting the kernel from USB was quite unreliable with 3.4.16. I tried to compile the 3.4.19 u-boot without success.

If you want to use another kernel, it can be booted from the spare flash (that OpenPogo uses) or from tftp/nfs.

Does anyone know the pinout of J1? Is it jtag and is there a diagram of which pins are which?

WPAYNTER said: Does anyone know the pinout of J1? Is it jtag and is there a diagram of which pins are which?
From the 7th picture down from the top in this post, you can see the pinout from the silkscreen mask -- seems unlikely it would've changed from the first spin. The signals are definitely JTAG:

3.3v

RES

TMS

CLK

TDO

SRST

TDI

GND

I am trying to make the cable everyone claims to make. I have the connector that plugs into the pogoplug side. i was trying to get the usb cable to serial connection setup, but from what i have read. i have no idea how to connect the connector that is from the pogoplug to the serial to usb adapter. below is what i think i need to do. can anyone please clear this part up.


i have this:
i found this:
does it connect like this:

October 14, 2010 11:08 PM

I found that the usb to serial was not going to work. I just went and got the nokia cable like above and will wait to connnect that cable. I will show some pic of the steps to create the cable also.

November 29, 2010 1:17 PM

What Digi-Key (or other manufacturer's) part number is used for the connector on a Pogo v1? Thanks.

December 1, 2010 7:42 PM

Without a close look at the Pogoplug PCB it would appear to be a typical TTL serial port. Look for a MAX232 or ST232 IC nearby. If it isn't there the port probably needs a TTL to RS232 level shifter (the MAX232 is ideal)

Ok, I am a total noob and managed to brick my Version 2 pink after just 24 hours of owning it.

I am not too technical when it comes to things like wiring but i have access to parts.

I want to reflash from a laptop without a serial port so if anyone could be so kind as to tell me how to how to do this it would be much appreciated.

Is there anyway of doing it without a soldering iron ?

February 12, 2011 9:21 PM

How small are your fingers? You can go to Kyle's page https://wiki.xkyle.com/Pogoplug and click on the picture to get the serial pinouts for the Pogoplug V2. You need to buy a CA-42 cable. You can get an idea of how to use the cable from plugapps http://plugapps.com/index.php5?title=Hardware:_Pogoplug_Pro_Serial but use the pinout from Kyle's page. You could go to Radio Shack and buy http://www.radioshack.com/product/index.jsp?productId=2062624&numProdsPerPage=60 mini-clip leads but make sure you don't short out anything. Do this at your own risk. Needless to say this would be a temporary connection.
If you do want to learn the art of soldering, you can buy a 15 watt soldering iron http://www.radioshack.com/product/index.jsp?productId=2062728 and some silver solder http://www.radioshack.com/product/index.jsp?productId=2062725 . Soldering tip of the day: Heat the work, not the solder. http://www.google.com/search?hl=en&source=hp&biw=1099&bih=633&q=soldering+les...

I used a CDROM sound cable to make the connector into the pogoplug board.

Excellent instructions/pictures of dis-assembling the Pink Pogo @sjhill

June 1, 2011 10:09 AM updated: June 2, 2011 5:35 AM

BTW - The pinouts for the serial CON3 port shown this page from Clloud Engines are wrong for the Pink v2 Pogoplug .  Mine is called a POGO-E02 as I live int he UK.

Brad  take note- it's not the same connector as the ver1 Pink Pogo.

Correct for Pink v2 Pogo (sjhill has them right if you zoom his picture:

  • GND  (Pin Closest to connector J1) 
  • RxD  (Will read as 3.3v with serial cable 'up')
  • TxD
  • 3.3v (I did not use this pin, farthest from J1) 

How do I know?  Becuase I just unbricked my Pogoplug using a Nokia CA42 USB to 3.3v serial cable and a CD-ROM sound cable as suggested from an old PC for the .200" connector.

My 'CA-42' cable had only 4 wires:

  • Black = GND
  • Green = RxD 
  • White = TxD
  • Red = not used

Here's a picture of my simple working setup:

Here's some other useful info:

I used XP hyperterm to connect to the serial port for the Nokia Cable using 115200,8,N,1,None

That's 115,200 baud, 8 data bits, No parity, 1 stop bit, No flow control.

To fix my problem, I had to boot to the shell promt and then:

Become superuser!

#su

Needed to edit a read only file system. You need to mount it as read/write with:

# mount -o rw,remount /

Then fix your problem (mine was 'chmod u+x rcS').

I had copied /etc/init.d/rcS and then edited the copy from ssh using putty.  Duh.  

It bricked because I didn't set the execute bit, so I lost Ethernet networking.

Then put the file system back to read only (or I think just sync,sync, reboot):

mount -o ro,remount /

Have fun.

Richard,

The last part is confusion for me....what are the exact commands which i need to give to do a factory reset ? I bricked mine Pogoplug V2 as well and now I dont see an IP adress anymore and cannot ssh into it.

Do i need to change some things in the Rcs ?

June 15, 2011 5:08 AM

This is a specific example of what I needed to do, which was to change the execute permissions for rcS.

You need to know what you did to brick your box. There isn't a "factory reset" as far as I know.

If you get in with a serial console connection, then you can mount RW and make changes to get networking up and running. Yeah, could be a startup issue for the your ethernet port and IP, that's what I was messing with as my DHCP server on my router stops working sometimes.

Sorry I can't be of more help. Start a new thread and ask or search for startup files on the forums once you get in on the serial post and can see it booting.

July 4, 2011 12:44 PM

hello,
very interesting post ! hope you might help me here. I got this ca-42 : http://www.amazon.fr/gp/product/B0006N2DJC/ref=oss_product
But it has 5 wires:Black, blue, yellow, red & white.
Does someone has plugged pogoplug whith this kind of cable ?
Tks in advance
Arnaud
