SanDisk Sansa c200 Series
Llorean:
Well, we know that there's at least a PP5024 and PP5024B (I think it's a B) in the E200 which doesn't have the video capabilities that the Advertising Flyer says it has. Another revision could exist.
But that is a very good point. Once code's running on it, one could conceivably attempt to reach different clock speeds and see which of our current targets it behaves the most like (at what point does it become unstable?)
It's hardly scientific, but it is a test.

It may seem off topic, but since the units are similar in many ways, it may be easier to figure out the diag mode on the E200 if it exists.

I wasn't able to get into a diag mode on my E200. I tried booting with hold on and each button pressed except record and select (which already do different things.)

The sheets cite the same numbers for both: 32kHz to 100MHz. I think the differences are due to mistakes on our part or possibly different clock gen speeds on different MP3 players. That or the sheets are optimistic.
Edit: The gold standard would be to take a dead c200, pull off the chip, and count the BGA balls on it. No revision is going to add another 70 pins to a CPU.

Don't look at me :)
But they are hard to kill. Yesterday I threw a e200 bootloader rom on it and thought I killed it, but went into manufacturing mode and loaded the rom via that and reflashed the proper rom.

... I take it you meant "recovery mode" there! ;-)
