If you like I might be able to setup a wiki to formally document more information

Thanks, very helpful blog entry.

My only nit is that you seem to be terminally confused about the difference between “its” and “it’s”.

I’m glad you got it figured out. If you don’t mind, can I mirror that image to prevent picasa from delete it? That’s a real good image to have as these CA-42 cables are pretty common but can vary wildly in the internals.

Oh wait I figured it out… If anyone has one of the generic chinese cables bought off ebay this should help.

I have a slight problem. After opening my usb serial cable I got off ebay I realized that it might not be the same pinout that you have. There is no markings that specify gnd, trx, or rcx. Attached is a photo… Got any clue what the pinout might be? Also it is the highest resolution that I could take.

@Martin E:
You are correct. Unfortunately in the EE world, I’m only a couple steps above total n00b so I wasn’t sure what the terminology was. I knew it wasn’t RS232 because that’s typically a +12/-12 power level, and had heard about TTL being +5v in working with some mocrocontroller projects I was working with.

I hope your serial port works fine for you! Enjoy your modded Dockstar and look for an article coming up soon in regards to the rest of the pins on that header!

@SupremeDalek:
I don’t think there would be a problem with it. I didn’t have much clearance and when I went to EPO to get parts, I was limited to what they had on hand.

@laptopfreek0
That’s a good question. I did notice that when my CA42 cable was not connected to the Dockstar, minicom would start spouting random gibberish like you said. Based on that, it sounds like your GND wire may not be connected properly and your RX wire has lost reference. Check the connections on your GND wire and your RX wire and you should be OK.

All:

The rest of the connections on that Dockstar are indeed a JTAG port. The guys over at Plugapps.com have found out which connections to make to a parallel JTAG in order to be able to recover from a failed flash. Since I’ve bricked my dockstar, I’m waiting on the JTAG cable to come in so I can learn how to do it and pass the knowledge on to you guys!

Comment on Hardware Porn: Seagate Dockstar teardown by firestorm_v1

@Peter:
After recent research, it appears that the rest of the pins on the connector are indeed a JTAG port. Since I’ve currently bricked my dockstar, I’m excited to validate and confirm this. Once I have my JTAG programmer, rest assured I’ll be posting an article here.

@cde:
I was thinking of something similar for the functionality of the device, but the idea of using the dock as a dock for the G1 is an excellent idea. I’ve been wanting to get ahold of a dead Freeagent drive but they’re too new to find cases for just yet.

@GZ:
Do you mean this article?

Hack-A-Day was nice enough to publish my article on their site.

Just tried this hack and when I hook the USB to the computer and open minicom it goes nuts, and keeps pushing out gibberish even with the dockstar unplugged. When I plug it in the gibberish just keeps scrolling. I am not quite sure but I think my dockstar is bricked, but even if it is I shouldn’t be getting gibberish when the dockstar isn’t plugged in. Any ideas?
