ah well... its not quite in the State i wanted it to be for a first Release, but i still decided to post a "release candidate". comments welcomed. corrections and additions are more than appriciated.

http://hitmen.c02.at/files/releases/psp/psp_doc.pdf.tar.gz

for now, take it with a grain of salt. there is a lot to be done, and there are probably quite some things that arent very accurate or even plain wrong (again, please let me know whatever you notice).

have fun...

Yep, lots of nice bedtime reading there, sterling work that man. :)

I think I may have some corrections for some of the ELF stuff, but I need to check some data first.

Gorgeous work. No complains and excelent reading material. Keep this up, its always good to gather a good compilation of what we know about the PSP system.

PS: Your work on the .elf file is great. Just a side note - The Verification process looks like a pointer to a command within the header of the elf file. (Not exactly shure where it is since it varies for each .ELF file.

Peoples!!! Where does anyone demonstrate that they have successfully used the PSP as a USB-OTG host? Just because "it says so on the internet" doesn't make it so. We need a repeatable demonstration that anyone can perform before we can draw any conclusions about whether the PSP supports USB-OTG or any similar capability. I'd like to know the answer to this as much as anyone, but let's find the real answer instead of just adopting the loudest rumor as truth.

Back on topic, this PSP hardware reference is excellent, and I will be reading it very closely over the next few days. Thank you for your hard work!

Very nice work groepaz. There are still many things missing,
but I think you can already call it "The PSP Documentation" not just "yet another..." ;)

Especially looking forward to the VME part, although I'm not expecting it anytime soon.

While you wait for your warranty to run out, take a peek:

(These pictures were taken by PyroSama.)

By the way, if you've downgraded the firmware or run any homebrew applications, then you've already voided your warranty.

in theory Yes but I've downgraded my first PSP (bought September 1st) and i had an analog stick glitch (mechanical glitch not software glitch) and at Micromania (Video Game Seller in France) they don't repare only change...so i gave them my PSP and they gave me new one (I already ask for a 2.0 but Only 2.01 or 2.50 are in stock now)...I'm in 2.5 for now and waiting the day of Full Homebrew Access...Anyway I think you voided your warranty if you brick your PSP....Thanks for the pict I'll have a look on them

Great work :)

I will have to get with you in the near future about updating the hardware section. I have a few cad drawings that could help fill out that part of the document.

Mirror: http://www.fwurl.com/psp_doc.pdf.tar.gz

Thanks,

................AS THE POLAR ICECAPS MELT, THE SEAMONSTERS ATLANTIC HEAT CONVEYOR SLOWS, MAKING HIM COLD, AND IRRITABLE..........

Groepaz- You sneaky ole sea dog, you've knocked the wind out of my sails again. From one seadog to another: Good on ya!

WTF do the "numbers" represent next to all these interrupts though? You might want to stick in a quick paragraph describing the interrupt topology. It would appear to this old barnacle that there are the 8 interrupts that directly map into the exception cause register, but it seems there is an "external" (I use the term looser than dead eelgrass floating freely on the water) interrupt controller to? Is that what the "mfic" related instructions handle? Now, usually in an interrupt topology, that entire external interrupt controller would be mapped to a single hardware interrupt line on the PSP. Which one???

(So, like, you'd get an Interrupt exception, check the cause register to see which interrupt. Ooops! Its interrupt X, that means its one of a zillion interrupts caused by this external interrupt hardware. So lets query the external interrupt hardware to see whats up.)

I'm just looking for the value of "X" I guess.

Keep it above the waterline, mate

its updated again, check the changelog for details :) this time including a lot of exception/irq related reversing (hopefully answers sea monsters questions :)) and flash related stuff.
