    Couldn't wait for my Pyra, so I bought a OMAP5432 devboard

    Welcome to the tiny list of active omap5432evm owners and developers. You can build a working µSD with Debian through makesd: https://projects.goldelico.com/p/gta04-makesd/ e.g.: /makesd -vk latest omap5432evm or if you want a newer rootfs you can use: makesd -vk latest -vr latest omap5432evm...

    Slackware inside Pandora.

    Hm. Difficult to diagnose without serial console :( Does the makesd image boot tot xfce4 on your Pandora? Did you just copy the kernel to the slackware image? Did you include kernel modules and device tree files (there was an important change there)? Edit: another idea: can you somehow share...

    Letux-OS

    Good news: I have found the issue with X11 setup. It was that the default xorg.conf used "omap_drv" which is an old backend driver of Xorg. It was removed in Debian Stretch so that it is not available. A simple update of the xorg.conf made it work. And, I have manually started the rebuild and...

    Letux-OS

    The registers are only (not very well) documented for dm3730 but not at all for omap3530. I.e. they may not even exist. Nobody seems to know (and it is a more than 15 years old chip design, so many of the chip designers may be retired now). If you are interested in details, there only think I...

    Letux-OS

    It appears to be an issue in the pvrsgx driver which likely manifests iself only on the omap3530 but not on dm3730 nor omap4/5. Background: there is a register section called "OCP" which seems to be not available or hidden on omap3530. It is written to if SGX interrupts are enabled - and there...

    Letux-OS

    It seems as if it is a patch to fix a slow frame-rate issue with the 3D GPU on the Pyra. Which appears to have negative side-effects on the OpenPandora. For some unknown reason we did not forward-port this to kernels newer than 5.7 and it is no issue on 5.10. Hence nobody noticed when testing...

    Letux-OS

    I have found the problematic change. It was backported and introduced after letux-5.4.43. AFAIR it is not a problem in newer kernels (e.g. 5.10, 5.15). Next I have to think how to fix it... Because it was added for an also good reason.

    Letux-OS

    BTW: to make autoboot work, run on the Pandora (assuming the Letux OS has internet connection) wget -O /autoboot.txt http://download.goldelico.com/letux-u-boot/OpenPandora/latest/src/boot.txt Or a similar command (change the -O path) if you have an SD reader on some PC.

    Maybe, can you copy the exact command you have used for makesd here?

    Boring to use Linux, When BSD is up on Pyra and Pandora?

    MacOS kernel is called "Darwin" or "XNU" and is open source. There was a port to the BeagleBoard (OMAP3 which is the same processor as the Pandora) long time ago but not updated to later releases. It is somewhere on github waiting for volunteers...

    Should I have received my final order eMail already?

    Maybe here: https://shop.goldelico.com/wiki.php?page=Product&product=3031 But there are still to be solved issues with shipping within the EU (different sales tax per country and no really cheap shipments: placing goods in registered letter was forbidden a while ago). Maybe ED could take...

    Slackware inside Pandora.

    Well, it is difficult to tell what is/was going wrong unless we can get a console log. This would need an adapter for the serial interface. Maybe <advertiment on> https://shop.goldelico.com/wiki.php?page=Products&category=Pandora </advertisment>

    Slackware inside Pandora.

    Did you also copy the /lib/modules? Otherwise the kernel will not find many drivers.

    I haven't checked the current component availability situation but I can produce some more if there is enough demand...

    Christmas Update - what happened 2021 and what will happen 2022

    It needs an extension for the alsa kernel driver (called twl6040-abe+aess) to load the firmware. This is included in the LetuxOS kernels - but neither debugged nor working. The "firmware" is somewhere on github - but needs to be repacked into a format that modern firmware loaders in the kernel...

    battery only reaches 87%

    Modem modules are usually directly connected to the battery because 2G may draw too much energy during transmission pulses. Otherwise one would need a 3.3V regulator that can handle 2-3A pulses and still have no significant energy loss. In the Pyra there is a 3-way switch in the charger chip. It...

    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)...

    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...
