1  Hardware and U-Boot firmware / Hardware / Re: Anyone used SPDIF for audio? on: February 24, 2010, 07:04:44 AM
From what I can see there is no breakout of those pins available (maybe I missed them). So you would need to connect to them directly at the BGA.

This type of thing has been brought up a number of times. There are MANY more features on the chip than are broken out even in the "developer" products.  Even in the upcoming GuruPlugs (which do better than the SheevaPlug, but are still lacking). Exactly why this is, is not entirely explained (that I have seen), but hopefully future products (and processor offerings) will fix those limitations.

There is a SLIGHT difference for the CPUs. The GuruPlug Servers (Standard or Plus/Luxury) and the SheevaPlug have the exact same processor.

However, the GuruPlug Display has a different processor. This one uses the PXA168.

It would be nice if Globalscale actually had all these listed under their product link, but for those that may not have found it otherwise here are links to the GuruPlugs:
http://www.globalscaletechnologies.com/c-4-guruplugs.aspx

One thing I noted on the Display page it indicates there will be two varieties (one HDMI and one Touch Screen variety, check the features page). The other thing that seems odd is the different styling and hardware sets of these different GuruPlugs. I am surprised by the level of variation due to the core processors. The product brief for the PXA168 is available and indicates it has video in, audio, and "5-in-1" card reader features. Another interesting piece is that it specifically states that it will support Android (for those interested).

I know this is early (since according to GlobalScale they are not shipping for a while) but I think a comparison of the general features and capabilities of the GuruPlugs (including the Plus) to the SheevaPlug would be useful once we have physical specimens on hand. I mentioned it in another post but I think it might be useful to make sub-sections of the current Hardware category to account for the different varieties. Although most anything done on a SheevaPlug should work on a GuruPlug (considering the core).

Oh definitely. This is specifically a development kit which is why I bought it. However I think many people are trying to design products around it (pogoplug for example) which really are not much different at present. As things go forward though there will be increasing need for simplicity and design. Future sheevaplug designs will hopefully be significantly different from this one (although that is my thread in the hardware area).

Everyone,
  If a number of people agree that general corrections are needed it would probably be best to start threads for each major area/feature/application (ex: Installer) that people have identified corrections for. That way the correct information for that piece is in one place and whoever owns/maintains (or helps doing so) can check it over and update their information accordingly.

We need to keep in mind that many people are not linux (or other OS) experts. You can argue that they will not being doing things to need these instructions but how often do you see "newb" requests for help? Information is more easily accessible. If anything open source really wants to have broad appeal things have to be simple or at least have steps that can be copy/pasted for the masses... Nowadays cheap, simple, looks good, and gets the job done often counts more than how WELL the job gets done so that needs to be taken into account also.

rooster,
  Thanks, that was one thing I had noticed and was correcting. Unfortunately for you it happened to be the thing that I was looking at when I started really thinking about this topic. My thought was more general than just the Installer though. I think there are a number of different areas (ESPECIALLY in the base documentation) that need correction.

I think we need to go about a general correction of instructions and cleanup of what we have out here. For example, I bricked my Sheevaplug (hoorah, but I was following the instructions...) and am attempting to recover it using the Sheevaplug Installer 1.0. I am already having to modify my steps though. In the README.txt (step 3 of installation) it instructs to edit the uboot-custom.txt file... a file that does not exist where stated. Instead it seems to be implying the uboot-nand-custom.txt in a different location (which would need to be copied over). In any case, this is just an example I have in front of me at the moment. I have ran across many others with missing steps, calling for missing configuration files, or that make no apparent sense. I think it would be useful for those of us interested to try to go through and clean these all up and make for consistent easy-to-follow instructions that make this platform more accessible to all.

In the meantime I am going to try to come up with a single, simple method to recover my poor Sheevabrick so I can get back to work with it.

Just my $.02, I hope that when they make the next version of the sheevaplug (hopefully sales will justify that) that they will actually open up all the capabilities of the processor. The kirkwood we have in there now is able to do so much more than what they have implemented on the board. I am not saying they need to put the actual interface connections on the board, but maybe terminal strips or such. With SATA, tons of GPIO, a second Gigabit Ethernet, Sound, Video, and more there are plenty of options even using the current chip. The box has enough free room in it too (especially without the dev board itself).

That being said, what HARDWARE features would people like to see in a next generation version?
