    1st batch

    Yes, the design and samples are available since beginning of 2020 and I have built a "hell/torture machine" during lockdown times as mentioned in some other threads (that was real fun to get the windshield wiper mechanics of an old Audi A4 on eBay for 10€ and mount it to some wooden plank)... ED...

    Creating an "empty" OS for the pyra

    Yes, that is the bug needing a fix. The fix has not been published yet. Will become part of letux-5.10.y and letux-5.14-rc4 next week.

    Creating an "empty" OS for the pyra

    Is there also a bounty for this? I may have fixed SGX - at least I can now load the firmware again. Without timeout error reports. On the letux-5.10.y or letux-5.14-rc3 kernels (plus the not yet published fix). But I have no user-space for really testing more (I did have some kmscube test but it...

    Creating an "empty" OS for the pyra

    I am not sure where you did fid -rt or -armmp? If there is something it is a glitch from transitioning the build scripts. It is all here: https://download.goldelico.com/letux-kernel/letux-5.14-rc1-lpae/ You can find a debian header package, but preferred is to use the git source tree. There you...

    Creating an "empty" OS for the pyra

    1. Letux is: www.letux.org and https://pyra-handheld.com/boards/threads/letux-os.81518/ 2. the U-Boot/DDR message may be that your board needs slightly different DDR timings setup. ED mentioned a while ago that there is a patch in PyraOS and I am not sure if it is missing in the LetuxOS U-Boot...

    What we learned and did during the last 6 months

    For GPS: just tried with letux-5.13.0 kernel (incl. one patch not yet upstream that fixes a boot issue). root@letux:~# cat $(./gps-on) ./gps-on: line 13: warning: command substitution: ignored null byte in input [ 955.045999] wwan_on_off_rfkill_set_block: blocked: 0 [ 955.051828]...

    What we learned and did during the last 6 months

    You could ask for support, e.g. on the pyra or letux kernel mailing list. It is a while that I tested the modem last time but with LetuxOS it did work back then. There is also some gps script to demonstrate basic functionality...

    running linux arm executables on Pandora

    Maybe show a copy of the console log with: * 'ls -l' showing the executable * 'file' showing the executable * 'echo $PATH' * running the command Then it may be easier to help.

    Accelerometer and magnetometer (Bosch BNO055)

    Handling sensors is quite a standard problem for all handheld devices software stacks. First activities go back to the (OpenMoko) GTA02. But AFAIR there is no "standard" besides Android/Replicant (or iOS). There, all sensors are mapped to some high level abstraction Java/Swift/Obj-C classes...

    Improve Volume Wheel Daemon (Bounty!)

    Well every choice has its drawbacks. Encoder wheel usually has small steps (sending impulses to wake up the processor to be counted up or down). It reports changes. Therefore there is no well defined "off" position which it can be turned to even when the system is powered off. And off-the-shelf...

    Improve Volume Wheel Daemon (Bounty!)

    It is just a little waste of SD card space for the twl6030 driver which is neither loaded nor used by the Pyra. But yes, the CONFIG can be removed which will also improve compile time a little.

    Audio Driver (with bounty!)

    Good news: 1. starting your image I flashed the card again (with a fresh download) and this time it did boot and run through the wizard. I checked that it is running your kernel build [ 0.000000] Linux version 5.12.1-letux-lpae (pyra@debian-buster) (arm-linux-gnueabihf-gcc (Debian 8.3.0-2)...

    Audio Driver (with bounty!)

    Hm. There was no wizzard. Just boot log on the screen and console and now a login: on both. And the message [FAILED] Failed to start Pyra First Run Wizard. See 'systemctl status pyra-first-run.service' for details. Starting Light Display Manager... Doing as suggested: root@pyra:~#...
