If you were able to install a normal OS, then it means this prototype was flashed with production versions of the Boot1 and Boot2.
Could you tell us the Boot1 and Boot2 versions? (home + 5 + 4 and then the 'about' button)
I wonder if a rechargeable battery can be installed or not - so I'll be looking forward to the PCB photos :)
Usually, DVT hardware is very similar with Mass Production hardware.
EVT prototypes features usually much more hardware differences, but we'see.
I don't know if asking this is againts the forum rules.
Would it be possible, for development and archiving purpose, to have a dump of the Boot1, Boot2 and Diags?
Performing this is quite easy once Ndless is installed: you just need to run my 'Polydumper' tool: http://tiplanet.org/forum/archives_voir.php?id=3829
You don't need to reflash anything.
On the 'manuf' line in the 2nd column, I'm just wondering which type the ASIC does report.
"Nspire", "Nspire CAS" or nothing ?
It should be either "Nspire CAS" either nothing.
On TI-Nspire ClickPad DVT prototypes, the ASIC reported no type, which let us mod them into TI-Nspire CAS very easily by just reprogramming a single byte in NAND.
It seems that the TouchPad DVT prototype ASIC chip does include the model type (CAS/non-CAS) which wasn't included in the ClickPad DVT prototypes ASIC chips.
