Benefits of a serial cable, which to buy and how to use it.

Thanks Gravis.

For those in the UK try :
@ £9.99. Handy if you are passing one of their shops.
or
@ £6.99
Inc. VAT, plus post.

I can confirm that it works with a Raspberry Pi, but will pay attention to the notes from Gravis when fitting to the Parallella.
There are a few tutorials on installation on Windows, including pointers to the necessary drivers, and connection to Pi. Most of these should transfer easilly.

Thanks, this will be useful for me, since I have no monitor to plug the parallela into.

Hi, can you update your post with the following information (I'm a newbie, and was struggling a bit with it ):

I am using PL2303HX based converter. As of this, I had to connect wires by myself, so there was no colors by default.
According to this post (viewtopic.php?f=10&t=845&start=20) you have to connect RX-TX and TX-RX and GND-GND.

Thanks for your post, it helped me a lot with debugging!

Hi,
I am using Adafruit FT232H Breakout board to communicate at TX/RX port with Parallella.
After Power ON I get:

U-Boot 2012.10-00003-g792c31c (Jan 03 2014 - 12:24:08) // <--- First Line

... (see more below)

Starting kernel ...
Uncompressing Linux... done, booting the kernel. // <--- Last Line

and after last line nothing more

No Promt for interaction with Parallella!

Why?
Does anybody expirienced same problem with Adafruit USB-UART Adapter?

Bye,
Daniel

By default, the serial console is disabled in new images.
