Is this thread still being used to post NIDs for the browser API?

I guess an externally powered MAX232 should work too (the logic threshold on that IC is definitely lower than 2.5V). The problem is that psp_remote uses the changes on the CTS signal (RS232) to find out whether the serial port is online or not. In the original montage, because the MAX chip is powere...

Well, this looks like quite an interesting device to hook into (debug messages and so on), and we know it's there... somewhere.

Anybody tried to locate that port?

Uart4ForKernel:
0x2fd96f62 - sceKernelUart4ReceiveBytesFix

I also found this new unidentified NID in sceHprm_driver (1.50) :
0x71b5fb67 - (Unknown). From the disassembly, this is most likely another "sceHprmIs(Something)Exist"

It's most likely possible to figure out where UART4 is by looking at the board That might be difficult, because AFAIK, the I/O pins used by Sony on its CPUs have not been made public. There is a chance that, by analysing the paths of the Remote Port and IrDa ports, we can find the general region wh...

I think everybody knows about the planned microphone/headset extension by now. If you look in one of my posts above, you'll see that there is a good chance that pins #1 and 4 are meant to be for the microphone input. Of course the only way we'll know for sure is when the microphone addon becomes ava...

OK, it took slightly longer than expected, but I built a serial line converter to connect the PSP Remote port with the serial port of a PC and was able to emulate the remote with software: http://nil.rpc1.org/psp/pics/psp_remote_s.png For more information, see http://nil.rpc1.org/psp/remote.html It ...

I'm fairly sure the VSH modules, other then vsh_bridge, are wiped before a game is run. Yeah, I'm not sure what really happens there. It would sound logical for apps to start with a clean environment and let them manage their modules. For some reason though, I was unable to load the PRXs I was inte...

Note that the code above does not work for decrypting/dumping VSH PRXs that are already loaded in memory. However, it's fairly easy to achieve that as well, if you know the name of the module you want to dump (which you can find from Vampire 's list for instance). The code below is not very elegant ...

As I had a little time and I am still waiting for some low voltage components to build a proper serial line driver, I played a little with the remote port and the remote and tried to identify a few more things. First of all, the pinout I use is based on mc 's description from this page Also, all the...

yeah... that's why I was being cautious in the first place. As soon as I get the proper hardware though, I'll be having a closer look at that serial line. AFAIK, nobody went any further than just snooping the serial communications between the remote and the PSP. Not to be dismissive of the work that...

Let's throw some more fuel on the fire... No idea how far we can trust this source (if at all), but according to edepot.com : The remote control (PSP-120) of the Sony PSP is actually replaceable with a more feature rich version found on many Mini-Disc and Walkman Disc players. For example, you can s...

Some of these match the Memory Stick files/folders.
I wonder what the HOMEBREW.TXT might be about...

Seeing the WM8750 specs, I have to agree that it would make sense to use its ADC features, and that the logical place to place an analog input would be in the remote connector. Looking further, it looks like the WM8750 uses a 2-wire serial interface, which is pretty much synonymous with I2C. I guess...

So far I've found that the clock generator and the WM8750 audio codec are the only devices that use I2C. That's interesting, because if the microphone is using I2C (which is something I also considered in above post, because I am aware of the planned microphone extension), you'd probably want the a...

A lot of us have heard that rumour... This doesn't look too far fetched a possibility (a lot of hardware these day has failsafe mode to allow reflashing of the firmware of a failed unit), but it is probably prudent to leave this as what it is: a rumour. Now, I've continued trying to guess what the r...

Good post! But from looking at this new information (and more pictures of the inside of the beast), I would tend to share gorim 's opinion that the serial lines we're intersted in have nothing to do with the ARM9 CPU. The more I look into it, the more I think the ARM9 is for WiFi and WiFi only, beca...

I too would think that pin 3 and 6 are used for RS-232 and RS-232 only. The logic behind that is that developers seem to use that port for low level system access (debug/console) and the last thing you want then is to sever this kind of connection for one reason or another. Now a serial connection o...

aha! So there's a 3rd CPU (ARM9) on the PSP? This device is becoming a hacker's dream by the minute... ;) The ARM9 has got to be the CPU that's responsible for serial I/O & firmware flashing, especially if the main CPUs run at 1.6V while the ARM only runs at 2.5. Basically, Sony were easily able...

Typically, if you want serial communication between a PC and a PSP through the serial port, you'll need to build something like this . You can even fit such a montage into a standard DB9 - RJ45 serial connector if you use a MAX233ACPP, which is pretty sweet. You can get free samples of these ICs fro...

OK, I have a few more questions about the remote control port, from discussions about firmare re-flashing using this port. 1/ It is a safe bet to assume that a serial debug/console mode is integrated in this port (through the RS-232 protocol). Provided we can figure out how to enable the actual debu...

Hi gorim . Thanks for pointing that page out. I probably should have been more careful in my statement. There is always a possibility that a port can be used for anything. My concern however is from a standard user's perspective. The idea that was mentionned above was to re-flash the BIOS from a sta...

Just to kill the idea of using the Remote Control connector for firmware programming, according to this page , this port is a simple RS-232 port @ 4800 bauds. This looks promising at first, but even assuming that you can "somehow" increase the baudrate of this port to the maximum speed ach...
