Otherwise I dont see any difference, the datasheet is your best friend.
There is no difference between the two you have mentioned, the bootloader and firmware is the same.
It appears that I'm just stupid :)
All that was wrong is that I've mistaken the ICSP positions on the pickit as it wasn't labled and I thought that the one with the different marking was the sixth :)
Changing it let me install the bootloader and then the firmware with PDFUSB. After that the PC saw it as a USB hub and the LED was on :) After I eat I'll test it on the PS3.
Edit: My brother ate all the food, so as I'm waiting I've tested it and it seems to work. The two folders and the aplications installed are working but the backup manager is not emulating the games, which might be normal as it is 1.0v :D The important thing is that I have a working way of flashing I/SO chips, but of course it's a bit too late, as someone bought all the chips in the country :D
Sorry my bad english =)
Plz helpme with ps3break v1.0 pic 18f2450.
How load on this chip new fw?
No FW was i download no support. My chip 16k and 48mhz with out bootloader.
Plz give link or give fw for my pic. TNHX =)
Finally I've managed to get the smaller version to work. But I wanted to ask something about the scheme I'm using:
The device I've shown earlier was exactly build by the above scheme. The strange thing is that when I push the button situated between pin 17 and GND. Nothing happens. I assume it's to reset the device or put it in bootloader mode. But nothing of both is happening.
The second device I build was much smaller, and I've removed the ICSP connection and the switch. For quite some time I couldn't get it to work, after installing the bootloader (I've connected the ICSP cables directly to the chip). The damn thing wouldn't start. Accidentily I touched something while testing it and the LED flashed. After several minutes of staring at it, I saw that pin1 should have 10K resistor, which I forgot was connected both to the ICSP but to pin19 too. The strange thing was that just touching pin1 booted the device. Touching it again restarts the device. For the moment I'm turning it on with a touch because my soldering station broke :)
The questions are:
1. What's the point in that pin17-GND switch
2. On my previous board, pin 1 was connected to pin 19 with 10K resistor without a switch and it works perfectly. I've tested interfearing with pin 1, but it doesn't restart when I touch it. Because I've packed the new device (trying to isolate it) I want to know if it will start working automaticly and properly if I connect pin 1 to pin 19, or continue using it like this :)
3. How am I to update those two devices. Both of them are no more seen in PDFUSB?
Thank you, again, in advance :)
You have made an incomplete circuit. PIN 1 needs to be connected to +5v via 10 k resistor, its the memory clear pin whether on ICSP or the IC itself, even if you look at the circuit the 10k resistor is connected to +5v, only difference is that the wire en route to 5 volt pin of the IC it also connects to ICSP as well . I don't want to put the technical details here. Do some research and read the data sheet if PIC18x550.
While the device is connected to the computer pushing button located at pin 17 will not result in anything, it is the bootloader button and is supposed to be pressed when the device is being connected to the computer not after wards.
I would suggest you to make two devices one for experimenting and the other to jailbreak.
It was strange that pin1 needed even only small amount of static electricity to boot the device (wake it up or whatever). I just wanted to know what exactly it does.

About the BTL button. I couldn't really understand what you mean. At first you say that the button does not work while it's connected to the pc, and after that, you that it works only when connected to pc. I've tested exactly that, and it doesn't do anything.
I forgot if these device were to be update with a 3rd software, after being flashed with a programmer (bootloader) and PDFUSB (firmware). First thing that comes to mind is USBHiD, but I can work on it when I get home.
Are there any compiled hex files for the new PSN/Online addition for a 20Mhz?
An update for a pickit2 programmer will be awesome.
Here you go, both PL3 for PSN and Hermes 4b PSN for PICKIT2, tested versions.
