    H.265 / HEVC hardware decoding

    The OMAP5 (Pyra's system on chip) was already sampling in 2013 when H.265 was ratified, so it couldn't possibly have hardware support for that. There is hardware for 8-bit H.264/AVC decoding (and encoding) as well as for some older formats, but don't expect it to work on launch day. And even...

    Reading logic states on EVM ports

    Careful there, IO cells are 1.8V or 1.2V. 5 volts will damage the chip. Get the "Data Manual" (swps051) to see which ball is capable of what. I just looked, the DISPC pins are 1.8V only. See https://elinux.org/GPIO

    Shortest newspost ever... for now!

    I thought a "set" of moulds means you have one pair for the base, one pair for the keyboard grill, one pair for the display back, etc. edit: ninja'd

    The tale of the cases

    Wasn't a French company supposed to concoct a plastic specific to the Pyra's molds with just the right viscosity, etc.? Will this new company's materials work fine with the molds?

    You'll hate this post. And you'll love this post.

    Unlike other sections, topics in Pyra News are by default sorted according to when the news was written. See the little down arrow next to "Start Date" in your screenshot. Since this thread is from January, 2016, you'll find it on the third page. You can change the sort order by clicking a...

    Which Sensor-Chip(s) are built-in in the Pyra Mobile edition?

    Wow, that's pretty good indeed. I was thinking of the crude heightmaps in offline car navigation apps (Sygic and the built-in stuff in cars) when I wrote that; I take my comment back. BTW, do you know an app that combines horizontal GPS coordinates with topography data? I figured the Pyra's...

    Which Sensor-Chip(s) are built-in in the Pyra Mobile edition?

    Well, the often repeated theory goes like this: barometers are used to measure changes in altitude. As you say, GPS is not very precise vertically, but if you average its readings over an hour, it can give a decent approximation of your absolute altitude. Meanwhile, a barometer can't tell you...

    GPD Win crashes

    That sounds a lot like what I had with my Sandy Bridge desktop. GPU power gating caused random reboots, especially with Firefox. Can you try adding i915.enable_rc6=0 to the kernel boot parameters? Or look for an RC6 option in the BIOS?

    Which Sensor-Chip(s) are built-in in the Pyra Mobile edition?

    edit: I guess I should be clearer on this: the Pyra won't ship with redundant sensors. It's just that the PCB has some extra "slots," so that if the preferred chips become unavailable, production can continue with an alternative without needing a change to the PCB. The wiki is just out of date...

    That took a while...

    AFAIK only blank PCBs have been ordered. Whether those become 2GiB or 4GiB boards depends on what chips are put on them.

    That took a while...

    The latter. Linux has a generic thermal framework, (which works as you said,) and most Android gizmos use that for throttling, so I would assume TI has tapped that for OMAPs as well. We may want to tweak the parameters for the Pyra, though. I figure it's not a good use of time to do that before...

    The plausibility of an E-Ink Display

    That was in the context of I2C buses, so it's 1 bit per clock and an ACK bit after each byte. @Rolf van Kleef meant 350 kilobits/s. That should be fine for the logo sized panels, but it's something to keep in mind when looking at larger ones. @Rolf van Kleef, do you have a source for that? In...

    DBP repository

    It doesn't help that http://pyra-handheld.com/repo redirects to https://www.pyra-handheld.com/repo/apps What's the difference/relationship between apps and packages? Are they both DBP files?

    Hase Development "blog"

    Hope this helps debugging. It was printed during a replay of that "debug game" match, right after turn 4 (iirc).

    Preparing for a Prototype

    How would you make the pegs for the shoulder buttons? ED said there will be a heat shield between the SoC board and the base plastic (if deemed necessary.) I imagine the alu heat spreader would go between that and the SoC board. If you use the base as a heat sink, that would be bad for the...

    Modularity and memory

    What gave you that impression? Memory prices have been slowly rising for the past year. Indeed. Napkin math says it'd have to be priced more than €100 higher than the 4GB version.

    Quite a bit for you to read!

    Perhaps they disabled the upper 4 bits because of the time skew (those lines don't go through the muxer, and thus are not delayed.) With no mux, the full 8 bits could be enabled, giving the claimed 192MB/s @ 192Mhz.

    Quite a bit for you to read!

    Combining this, this, and a bit of this, i get : MMC1 — left SD slot — 96 MB/s MMC2 with direct connection to µSD (4 bits) — 96 MB/s MMC2 with direct connection to eMMC (8 bits) — 192 MB/s MMC3 — WiFi chip — 24 MB/s MMC4 — right SD slot — 24 MB/s (MMC5 — not available on OMAP5432 — 48 MB/s)...

    Where are the antennas situated?

    The 4G antenna module is hard to miss — as mentioned above — it's the blue box at the bottom of the picture. It has everything the cellular chip needs, including GNSS. WiFi needs two antennas — one for 2.4Ghz, one for 5Ghz. The former doubles as the Bluetooth antenna. As for location, i think...
