I'm pretty sure R20 is a 10k. It's just a pull-up for the switch (ie 1k or 10k would work but 10k is preferable).

RS-232 pin2 and pin3 have most probably to be swapped
I mean, my board has it swapped, but i didn't tested if my cable is a pin-to-pin, but it should be

Here's a better schematic. Its a tad large, but at least its more legible.
I hope I got everything right, but I'm not 100% sure on R20, if its supposed to be 10k or 1k. Can someone validate which one it should be???

R20 is correct, it's supposed to be a 10K resistor pull-up. You might specify it's recommended to use 1/4 watt (0.25w) resistors for best resolution/precise values.

Edit: Sorry, you already did specify it.

I thought Avalaunch was already ported to the 360 on a dev box almost a year ago? Wonder if that really got anywhere or not.

No it was not ported,Avalaunch is just running under emulation mode.

Hooorayy!
Sounds great

But creating that board besides the mod chip seems still pretty difficult atm

And here it goes again, let me repeat:

Team XBMC does not plan to work on "XBMC360".
But since we're Open Source anyone who wants can port our code!

Let the porting begin (not by us though)

Yeah but when u'r team (hopefully) complete the linux port in near future it should be possibly to compile it on ppc gentoo running on a 360 as soon they manage to get hardware gfx drivers instead of framebuffer

personally i'm just waiting for that to buy a 360 which will replace my xbox in my living room

Hi, i made a PCB layout...

that will ease up the DYO a lot. for people who cant wait for the infectus stuff...

here are the high-res PDFs to do it. bottom layer:

here comes the top layer (a few bridges need to be soldered)

Dont use that one its wrong, the 10K resistors on the outputs of the comparators should be pill ups NO pull downs - he got R20 right though Wink

Use the 9.50 boot loader I posted a link to at the beginning of this thread, the 9.0 has a bug (cjack noticed).

i have attached the correct diagram (IMG:style_emoticons/default/smile.gif)

Is there any "leeway" in the crystal?

say could I use a 24.576 or 16.9344, Or does the best/only performance come from the 20Mhz?
