Short term I dont care about write support, as I wont have two chances
to rewrite the DoC, if I screw things up, the only thing I will be able
to do is get the device back to service (and they wont want to repair
it, I opened it...)
Unless... Is there some means to access DoC through JTAG ?
I've seens some pages saying it works, but I'm not too sure it actually
was speaking of the case I have : A PXA and a M-Sys DoC.

Mh, what is "compatibility with M-Sys stuff" ?

I'll have a look at it ;)

64MB, 3.3V, BGA, yes ;)
Picture here, to confirm (I actually forgot the 1 after "333"):

This is it. Is chip ID 0xa5 ?
Cheers !
