    It is connected to the proper USB3 OTG controller in the OMAP5 so it can be used for faster transfer speeds with peripherals (hard drives etc) or even PCs.

    That is the microUSB-3 OTG port. The "sidecar" bit contains the extra full-duplex SuperSpeed pairs, in addition to the regular USB 2.0 signalling (so it can either be used with an old USB2 cable or a new USB3 one).

    Open Pandora - 10th Year Anniversary

    Feel a bad sad I missed out on the orignal Pandora, I remember preordering on the first day of preorders, September 2008 I think it was. I was so excited that I got in trouble for doodling something about the Pandora in one of my school books. But then my parents didn't want to continue by...

    Gah, was hoping to start playing with TILER stuff over the weekend but UPS have sent my uEVM on some kind of scenic tour, stuck in Tamworth for two days and now inexplicably ended up in Dublin - must have been loaded onto the wrong truck or something. It's now moving further away, in Cologne -...

    I think the logo plate actually looks better with the dark chrome, as it gives the whole thing a more 'metallic' feeling.

    Dark chrome looks incredible!

    Thanks for clarifying the kernel situation! U-boot contains the kernel command line which has some rotation and FB-related parameters, even though it doesn't set anything up itself, but it seems like https://dev.pyra-handheld.com/kernel/pyra-uboot is what to work with.

    Where are we now?

    I see, just to double check, where are the most recent kernel and U-Boot (so I can see the kernel command line) where TILER is known working? https://projects.goldelico.com/p/gta04-kernel/ suggests it works for 4.19 but not 4.14 or 5.4, but it's slightly unclear whether that is TILER or software...

    I have been looking at https://dev.pyra-handheld.com/kernel/pyra-kernel, is that correct?

    Great, I'll try and have a look at that. Hopefully I can get a test case of the TILER running with a EVM and a HDMI display rotated 90degrees - the opposite of the Pyra situation using 1280x720 as 720x1280 but should hit all of the same issues.

    I am also interested in helping with Pyra kernel development, my "day job" is FPGA tooling so I'm fairly used to working at a low level including a tiny bit of kernel hacking in the past (not so much on the driver side though, more memory management and interrupt stuff). I can't commit any...

    Interestingly, on the thread about a replacement CPU board, it is actually pretty hard to find a good replacement for the OMAP5 - while there are some AArch64 replacements now, in terms of raw CPU power they are pretty close or even worse (and anything more powerful has...

    Future of the CPU board?

    I've heard SiFive are making a massive loss at that price point too, because their aim is to attract developers to the ecosystem rather than make money selling SBCs (their main business is selling RISC-V and associated IP) - I think this goes to show the cost of low volume silicon.

    Pyra as smartphone replacement

    Looks like there is a single CSI lane broken out to a connector on the main board so maybe hacking in a camera will be possible if there is some room to squeeze it in, there are some pretty tiny cameras these days (I might have a go at this if a spare case is cheap enough if I ruin things).

    Future of the CPU board?

    I would love to see an open source graphics card, even if it is just on an FPGA, but the problem with any RISC-V SoC is the cost of a tapeout on the kind of process a Pyra SoC needs - many millions for a proper mask set, hundreds of thousands just for an MPW, not to mention software and...
