Hello all. While I am new here, I am no stranger to the world of portable electronics or integrated circuitry. I am certainly not a professional or even a real guru, but I am familiar with how such things work and learn quickly. Anyway, I came across an interesting article relating to the main SOC that powers our Fuze’s, the AustriaMicroSystems AS3525. Here’s the link.
Anyway, a few questions regarding the information in that article. All of these questions are referring strictly to the hardware potential, as future FW versions or possibly upcoming RockBox builds could, theoretically, unlock any features the hardware is capable of.
Does this actually mean that the chip runs Linux, or is capable of it? Or just that the core logic is Linux-based? What exactly do the Linux references mean, and does anyone know what benefits this may have? Say, is there a possibility of running linux-based code, or even a simple linux build on our Fuze’s?
I understand that this chip is capable of 3 different audio outputs, with one optimized for headphones (which presumably is what comes out of the headphone jack), another optimized for stereo speakers, and a basic line-out. I’ve read some of the threads involving line-out possibilities, and I would simply like to know if either or both of the other 2 outputs is usable in any way on our Fuze’s. Is there a pin connector allowing output of true line-out or stereo speaker optimized signal, and are these features even enabled in this application?
2a) If so, I understand that the headphone jack is directly attached to the mainboard, is there anyway to switch outputs through the jack itself between the three? If possible, it would be great to unlock such a feature in a future FW, allowing you to switch between headphone output, speaker optimized for a basic speaker or stereo setup, and line-out for a high quality system. Of course I realize that this, like everything else, is entirely dependent upon hardware configuration, and honestly this possibility seems a bit unlikely…
- Lastly, I notice that this SOC is capable of running flash, as well as various Nintendo emulators. I wonder if the hardware in this particular application is capable of running flash based games (maybe written for linux?) or even the Nintendo emulators (using the wheel as a d-pad, and the center and home buttons as a and b…).
I realize that those are fairly complex questions, and being that they relate entirely to the hardware potential, not what is possible with the current firmware, I don’t expect many people to know for sure. But if you do know or suspect anything, I’d love to hear what you think. Or if any SanDisk employees want to share what they know or are allowed to say, I’m sure we’d all love to hear it!
All hail the AS3525!!
