Serial port

Please read this topic;

It seems that they use the serial port for "emergency flashing" the device. They also could use the same for the first flash...

PSP port

For the tests we did I think we took a clear idea that it's a low-speed serial port, or if you want we can assume it could go to a maximum of 115200 bauds (the maximum serial port standard, if I'm not wrong). So It's not possible to use it for high data rates, such video or something similar, but it...

Linux on PSP

For what I've read I think linux developers involved in PSP have been very very very optimistic in terms of what they will be able to do with PSP. It's just my point of view, but I think that sony has done things well (in terms of security) and if they don't decide to share some information or perha...

A little of bash for linux users

This does more or less the same in a linux environment;

#!/bin/bash
echo 'Connecting to update page...'
wget -q http://fj01.psp.update.playstation.org/ ... telist.txt
echo 'Updates available;'
cat psp-updatelist.txt | grep Dest | awk -F\; '{print $2}'

Yes, 1 is tied to GND... so power don't come from there. I've uploaded a pair of higher resolution pics of the remote circuitry in my webpage.

I already tryed audio ground, but It's not conected with digital ground in the controller. It works equally, but I think blue(I don't remember exactly) cable is the proper gnd (at least the one used in the small pcb).

It's not a standard I2C, it's a very strange protocol, the PSP first downs one pin for a long time, then the controller responds doing the same, and later the PSP asks for something (some kind of frame) and the controller responds with four bits (if you don't press anything). So it seems a one line ...

Ok, let's try the easy way... If you desolder yellow cable the remote controll does not work, so power may come from that line. I guess that if the chip says nothing when the PSP asks, the output power is disabled...

Yes, I did use an oscil.loscope to look at all the signals, and while most where fixed I saw those variations in pins 3 and 6 suposed to be due to data comunication, and since 3 is periodically changing I supose It was PSP asking for something, while the other is the response (it changes when you pr...

PSP remote control pinout?

I was thinking on building a small pcb that permits to hear the PSP in any FM receiver (your car radio or your hi-fi home system), but I've got no idea if the remote control connector (the 6 pin flat one) has any signal of power (+3'3 or something similar). Any idea?
