    Yes. But you can also manually choose the OPP. 1 GHz has a limitation. There was a technology from TI called Smart Reflex to automatically adjust the OPPs (especially the core voltages and also dependent on chip temperature). Unfortunately this driver never arrived upstream in Linux and the...

    After cpufreq-set -g performance I get The governor "performance" may decide which speed to use within this range. current CPU frequency is 600 MHz (asserted by call to hardware).

    Slackware inside Pandora.

    This can be ignored. There is only a bq27500 fuel gauge inside the Pandora and the bq27000 is reported wrongly by a kernel bug. This is a design flaw in the omap3 device tree where the HDQ driver is enabled by default. Even if it is not wired up physically. And the HDQ driver assumes that there...

    Not actively. But there have been a lot of patches upstream, including the bq27500, in the past years.

    Slackware inside Pandora.

    No, it is just included but can be disabled by choosing a different govenor. E.g. cpufreq-set -g performance should work. Depends on desired power saving mode.

    Slackware inside Pandora.

    This is the time U-Boot needs to load and start the kernel and the kernel to initialize everything until it has loaded the display and LED drivers. Before it has done this it can't display anything. Well, there are mechanisms to speed this up (google for "Falcon Mode U-Boot"). This would take a...

    Something is wrong with git.openpandora.org

    Likely the server has changed some configuration (upgrade, reinstall or whatever) and public git: access is no longer available. Similar to https://blog.readthedocs.com/github-git-protocol-deprecation/

    Seems to be broken for me as well. But it is possible to download a "snapshot" if that suffices.

    Maybe, run the "top" command, it tells which processes eat up processor power (or memory?). And yes, SD bandwidth with dd should be around 20 MB/s. 1753123546 This is something I have seen as well, but only on the Pandora and no other OMAP device. It is not clear what the reason for this is...

    Slackware inside Pandora.

    Ah, I see what you want to achieve... The standard kernel command line sends the boot process to the serial console (/dev/ttyO2 = UART2) and not to the screen. Try to change in boot.txt setenv console "ttyO2,115200n8" to setenv console "tty7" (and build a new boot.scr using mkimage). I am not...

    Slackware inside Pandora.

    Great to read about some progress! About the strange "Usage: itest" message I have no idea. The only explanation is that you are using a different U-Boot that does not understand the itest command in boot.scr. The kernel can't repair broken file systems. It needs to be able to boot and run fsck...

    Slackware inside Pandora.

    Hm. The screen shot shows that the itest command of U-Boot is working but not from the script. So there is an issue with the autoboot.txt mechanism or file. But your setup looks to be the same (at least from file locations). I have attached my autoboot.txt (pulled from the working SD card) to...

    Slackware for Pandora 14.2

    Any recent kernel should work... But I'd recommend to take the latest LTS (Long Term Stable) kernel which is currently 6.12.37/38 (https://www.kernel.org), because it will get updates for the next handfull of years. LetuxOS provides these as "letux-rolling-lts"...

    New to Pyra, Debian Bookworm bugs?

    Indeed. This reminds me of the first tiny batch of Pyra motherboards where the production site didn't realize the speakers weren't supposed to be soldered (they're actually meant to be press-fit). The springs made the speakers jump around in the reflow oven and they had to clean it...

    So where are we with the Pyra--really?

    Well, to be honest, this is a really big project. I'd expect a set of challenges, just elsewhere... Will need two month, ahem, two years to come close to what the OMAP5 already has :) Me too, which is also a factor... BTW: making AESS is not forgotten but covered by a pile of other topics and...
