The links says the CPU is in 12nm and the GPU in 16nm, where did you see it was 28nm?

Looks like i was wrong, For some reason i thought only the i.MX8 M and X existed. Anyway i don't know much about the details of these SoCs so i have no idea about they compare in TDP, BSP support or graphics performance, but as the Amlogic wasn't being discussed here i was wondering why. From...

The problem with the iMX8 is that it uses A53 cores, which are actually slower than the A15 ones. As it has more cores it can compensate for it in multi-threaded workloads, but it will remain slower in single threaded ones. However i would like to know what the general thoughts are on the...

I fully agree, but as there is so little air inside the case and no ventilation holes I don't think it will be cooler than the cpu for very long :S. That is why i suggested replacing the heatsink with a copper block (basically a heatsink without fins) so it has more thermal capacity than the...

Just a small concern, but the fins on the heatsink are supposed to enhance the cooling by convection of the air around them. As they appear to be placed inside the case, they do not seam to have a lot of space for air to circulate around them. Taking this into account wouldn't it be better...

It can take some time for the system to become responsive again when it's using a lot of swap, but the OOM killer call does work. Had to wait up to 5-10 minutes once, but I was able to recover some important work that i would lose otherwise. The time it takes to recover depends on the amount of...

reisub is just a subset of the commands available with SysRq, they are the more commonly known as they are usually the best course of action when something goes wrong. R - to prevent X to catch some keyboard inputs, which is useful for debugging, E- to send the equivalent of a Ctrl+c to every...

Are you sure you are pressing SysRq? As it is usually bellow PrintScreen you need to do Shift+PrintScreen to activate it, so the full key combo becomes Alt+Shift+PrintScreen+f, this varies with keyboards though. The other possibility is the SysRq combos being disabled in your system, this link...

You can always use Alt+SysRq+f (yeah that key usually paired with print screen that no one knows what it's for) to call the OOM kill function. It's really useful when everything locks up due to swapping. The other option is to disable swap altogether and the system will call the OOM kill when...

From the way he talks about his nokia n810, pocket chip, noodle pi and similar devices (which i suspect he collects :p) he will probably love the pyra, even if ED doesn't send him one I'm sure he will buy it for himself if he ears about it. I bet he has never eared about the pyra or pandora...

Let me start by clarifying that I agree with what you say, i just argue that if the software is not flash-able it probably will not implement superfluous features that add no real value apart from a bigger spec list. If it wore flash-able, doing such a thing would not be a problem as you could...

That is true, but it is also true that a bad enough bug would require a recall instead of a software update, such a recall would imply huge losses for the company. And if there is one thing these companies truly care about, it's money.

Non flash-able ROM is actually a good thing, mainly for 2 reasons: - It means no malicious software can be installed on it after the chip leaves the factory. - The manufacturer will write the simplest software possible for it as it will not be able to fix it latter with an update, this means...

Those modems usually come with the call feature deactivated. You probably have to activate it either in their software UI or with AT commands you send into the ttyUSB. Last time I played with a modem like that (a 3G one) i had to do a firmware update to be able to activate voice, and IIRC after...

Tritium usually does not escape as it is stored inside small tubes that fit in the hands of the watch and the hour indicators. It does decay with time and as it has a half life of around 10 years so it halves the brightness every so often, meaning that your watch would be emitting a glow now...

The battery life of the pyra as a phone will depend if the modem can wake up the pyra from sleep (S2 or S3 state) when it receives a call/sms. Does anyone know if it can?

What about the embedded version of the snapdragon 820 that was announced in February? Could it be obtained for the Pyra?

Just remembered but should it not be possible to get a thinner battery heat shield and slightly higher connectors for the cpu board to connect to the mainboard? How much space could be gained from such changes?

The size is on page 28 and acording to it, the thickness is 1.41 to 1.61mm with solder balls included. So it would be possible if we could get the minimum value, it seems unlikely but my knowledge about this stuff is almost none :(. Edit: Looks like I took to long to answer...

Usually you don't want to do that as "race to sleep" is a more power efficient strategy. As the system already downclocks to the minimum possible when there is no load, you want to finish the tasks as soon as possible (highest clock) to then spend most of the time in the lowest clock. Disabling...
