I also tested [something or other].

Yes It's possible, and Sony could also give us the encryption keys.... It would really surprise me... Serial ports are often used as serial ports...

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...

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...

E is sometimes used for voltage, as It can be used U or V.

In fact games are not region protected (by the moment) just videos (music has not been released yet, so it's not tested, :P).

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...

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}'
rm psp-updatelist.txt

You agree with me that Yellow wire+2.5V (? RTS?) must be power line?

Great job!!

By the moment every thing related to PSP is in a quite early stage... but I'm sure there will be a lot of people interested in a lot of dev including graphics of course, but we will have to wait...

I think Image Converter is not freeware... so better don't post thinks like that...

P.D.; something to say forum administrator?

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.

Yes, sorry, I didn't remember... I will verify pin1, just in case...

Sorry, I meant CTS...

Yes, I also think the same, but still have no idea where power comes from, perhaps the RTS signal?

P.D.; what's your webpage?

I have uploaded a pair of osciloscope captures, images, and raw-data, the first (TEK000) corresponds to the startup process, when you plug the remote controller what happens. The second one is the periodically interrogation that does the PSP. The probes conections are; BLUE-GND YELLOW - CH1 ORANGE -...

If you want you can download a document I've been writting summing up all those things... it's available here; http://www.comerma.net/PSP/ I'm still working on it. Let's hope today I've got time to make some oscil.loscope captures...

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... don't trust very much what I've said... It seems that SCE likes to do things the "hard way"... someting as simple as powering devices become very complicated. What I've stated by now is that when you connect the jack, starts a round of qüestions/answers; the psp brings power up form ...

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...

Finally hi opened my controller and those are the results; looking the conector from the front of the psp I numbered the pins like that; 1 2 3 - - - O - - - 4 5 6 And the jack ones are 7, 8 and 9 (7 is the contact in the end, 8 the middle and 9 the bigger, usually gnd). They correspond to wires colo...

For sure I will make some tests...

I don't remember exactly how it was an audio signal to headphones, but could it be possible to extract power from that?

I just ask if someone knows it... :P

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?

Of course I'm interested, and I hope all users of free software too. I'm tired of using 3GPConv (an excelent tool, but just for one system/platform).
