I hope you can help here. I've just started working for a new employer and one of the first projects I have is to develop and interface/reader for Sony's memory cards. CF and SD cards, IDE and SCSI I've done before and the information was pretty much readily available. In this case however, Sony's protocols for communication with their cards at an embedded level is a bit obscure and non-existant.
The MG technology I believe is an encryption algorithm applied to the cards to 'lock' them, it was originally pushed with the Playstation 2 as allowing the storage of online customer information, bank account details, passwords etc.
Is the MG function always enabled? Because if it is I'm dead in the water from the moment go without that algorithm.
Would anyone have any experience in interfacing with these cards, please any info? It'd help me out loads as I'm just sitting here doing all of the other background work surrounding the project in the meantime.
Any help very much appreciated,
