Dumping PS3 Hypervisor and Bootloader with Atmega8 at 16Mhz

[khetzal]

Hello, sorry for upping this old thread.

I've just order all I need to make this assembly, but i've two questions:
- Is it normal that the ground and the +3V are linked ?
- Where do you take +3.3V ?

Thanks you a lot.

Thanks you a lot.

There is a new method that uses LPT which is way more cheaper and easier. Why don't you use it?

I hadn't see that there is a new method Thanks you for the information !

But now i've order the atmega8, i will be happy if i can make it working too.

I've seen someone talking about a MAC modded keyboard, I've already told about a modded keyborad (not a MAC one indeed) to speed up things but seemed no one had the wish to wreck a 5$ keyboard to perform the hack with a bit more ease...

Furthermore, rereading I've seen now many ones talking about 3,3V... but... XDR of PS3 works on 1,8V, it's not that feeding it a 3,3V pulse could set up a big mess into it ?

In my opinion, the 3.3V is not send to the ps3, it only feed the avr (there is normally no power send to the ps3, only a link between the xdr and the ground is made)

You could take 5V from the USB port and add a resistor. AFAIK the AVR can operate at 5V, too - check the data sheet.

And yes - the connection between Vcc and GND shouldn't be there. That mistake was pointed out to the author on the first two pages but it looks like he didn't provide a fixed schematic afterwards.
