To hook it up in-circuit, one would have to find a way to keep the nand-interface in the CPU from hogging the bus. Probably by cutting the traces, which is...messy... Actually, it may not be as bad as we think, with some hardware purchases: http://www.stencilsunlimited.com/bga_stencils.php Then jus...

Thanks for the help!

I'm just going to try dropping the 5v lineon the PC, to see how low the board will work. I'm not actually intending to do changes to the flash yet - I just want to be able to image it. So I'm probably going to end up ripping out the ECC code.

Cheers,

Allan.

I now have 2 PSP motherboards to play with. They have busted connectors and I haven't got the button sets... But for initial playing, they should be fine. First task I'm interested in is (obviously) reading / reflashing a NAND flash to be able to recover a brick. Unfortunately, it appears that most ...

How would that work? (Not doubting that it would, just intensely curious.) The flash chip in the PSP has three distinct regions that would need to be programmed. Would these appear as separate partitions? I was under the impression that a regular SM card would only present a single partition to the...

Am I misunderstanding this, or is SmartMedia just a direct access NAND flash chip? Surely a flasher can't be as simple as just a $20 USB card reader and wiring up a dummy smartmedia card to the traces already identified...? I had a similar idea. (Great link, BTW!) This will probably require custom ...

What's wrong with opening it and cutting traces?

If it's a brick anyway... :)

Cheers,

So now we have all flash pins identified as externally accessible. What stops us from cutting the tracks (possibly /CE and /WE only), chemically stripping the enamel off them and soldering on our own board with a http://www.samsung.com/Products/Semiconductor/NANDFlash/SLC_SmallBlock/256Mbit/K9F5608U...

To be clear, they *cannot* use the XviD codec in a commercial application, without providing source. So what they're doing is breaking the license agreement for the XviD codec.

Using the XviD codec directly.
