Guys, these kits work sweet:

http://www.sparkfun.com/commerce/produc ... cts_id=133

Only $6.95! You will need to connect VCC to get them running, great for a freshen up of your soldering skills too.

;)

Does Kurobox Pro need any special operation to get the front side UART0 to work? I have tried to get it working with minicom in Ubuntu 10.04 but I can only read data, I'm not able to write.

This is quite annoying since my u-boot has the boot parameters set as 115200 xxx /dev/mtdblock2 instead of root=/dev/mtdblock2, so the Kurobox Pro won't boot up :/. Any tips on this one?

I'm using the http://buffalo.nas-central.org/wiki/Add_a_Serial_port_to_the_ARM9_Linkstation#Usage_considerations_for_the_TTL-232R-3V3 cable I got from Mouser and it is soldered properly and should work ok, but I still can't write to /dev/ttyUSB0, even after using sudo and modifying the serial port options with stty, so I don't know whether its a software or hardware issue?

EDIT: If you need more information that I didn't probably remember to post here, please ask :)

Hi,

Which header are you using? the bottom one on the daughter board?

You can now find a USB TTL converter on Ebay (usually shipped from china) for less than $10. Just search for
"USB TTL", at the moment using buy it now, the cheapest one is $5.60 with free shipping, comes with patch wires too, all you'd have to do is buy and solder in a pin header, (which you could find for a few cents anyway)

Yes ramuk has a good point... I have come round to the 'Single device' thinking now too… saves on stuffing about with USB to serial converters...
I now use one of these:

http://www.pololu.com/catalog/product/391

Works perfectly I’m very happy with it! has drivers for Windows, Linux and Mac OSX too.

I got burned on a cheap eBay one… so just be careful and ensure that drivers are available (and know what the chipset is) or I would suggest you go with the pololu.

:)
Stonie.

If you absolutely must have one right now, right here, right away, you can go to radio shack for this:

RS 20-546 USB Cable
It's pretty expensive at $35.

RS 20-047 USB Cable
If you are lucky the discontinued older orange cased model will be around, selling for $20. These have an FTDI chip in them
the pinout is:

Here is a reference that lists the cable, these are ordinarily used to connect a computer to a handheld radio scanner (to program it presumably).

Just a bit of sandpaper to scuff off the Radio Shack logo and you're good to go.

HaHa! I bought one of these yesterday, with a CD rom audio cable I found at a local computer store

and a 3.5mm audio jack and some wire stripping and wrapping to the posts of a 1/8" stereo jack and I was in business at my in law's house to debug a kuro-pro
