According to http://hitmen.c02.at/files/yapspd/index.html

CXD2926 listed as Graphic Processor Chip
CXD1876 as ME

What is actually what? First one has GPU and CPU then? And ME just co-proc?

Both(?) has MIPS cores. Flash connected to Graphics Processor. What for? DDR also connected to Graphics Processor. Reasonable. Is the Media Engine just slave to Graphics Processor? Or those are peers? Where OS is executed? Which chip executes decrypted IPL? Which does decryption? Do we have dual cpu...

I would love to discuss that here again. Cause psp has no stand alone host chip - just phy - what is in cpu nobody knows - and it might be anything. And there are phy chips which may be turned to host or func modes on fly. btw I worked for USB since NT4 - bunch PC host drivers, bunch functions for v...

The PSP does NOT have host capabilities. Period. End of story. Look at http://forums.ps2dev.org/viewtopic.php?p=39489#39489 I strongly doubt Sony will turn PSP to different functions (quite hard to implement and it is very stupid design) - as by there mic, camera, gps and etc. There is not usb host...

Its expected to connect at least camera and gps - so psp shall support both functionality(means client and host).

Don't you think the eeprom also shall be multiple and dumped?

Nice joke :) xray :D

Man - its better not to use camera but scaner ;)

It's no good if you have a conflict when you try to assert WE and the CPU want to deassert it for instance :) Bet if you will keep reset low the CPU wont even try to do anything and all pins will be in high-z. So you can access Flash that time safely. Probably it possible to make some nail pad whic...

But the updater gets access to flash0:// somehow. Guess does it from userspace. Does that means that there rights for app also encripted in?
