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

    Ok, here is the backtrace: (gdb) r -c 2 /bin/echo Starting program: /root/pyra_vol_mon/pyra_vol_mon -c 2 /bin/echo Found IIO device with name palmas-gpadc with device number 2 *** Error in `/root/pyra_vol_mon/pyra_vol_mon': malloc(): memory corruption: 0x00415420 *** Program received signal...

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

    Hi, have pulled the files and they compile fine (there were just some whitespace errors). Unfortunately it does not run: root@letux:~# /bin/sh -c 'cd /root/pyra_vol_mon && make && ./pyra_vol_mon -c 2 /root/pyra_vol_mon/pyra_vol_ctl' gcc -MT .objs/pyra_vol_mon.o -MMD -MP -MF...

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

    One more idea (unless it is already there): the tool should call the subprocess once with the current value when the monitor daemon is started. The idea behind is that someone may have turned the wheel while the daemon wasn't running (e.g. power off/reboot) and expects the mechanical value to be...

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

    Ok, I have fixed the boot issue and now have a letux-6.1-rc2 kernel running with display :) Yes, volume wheel needs the channel 2 and then it works: root@letux:~/pyra_vol_mon# ./pyra_vol_mon 2 /bin/echo Found IIO device with name palmas-gpadc with device number 4 666 704 736 775 815 850 884...

    Devuan Chimaera + error: wl1251: ERROR could not get firmware: -2

    You can very likely download the firmware-ti-connectivity.deb here https://packages.debian.org/stretch/all/firmware-ti-connectivity/download and install it through "dpkg". It contains these files: https://packages.debian.org/stretch/all/firmware-ti-connectivity/filelist which includes...

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

    The best solution would be if you can push to some github repo and open new branches for each version of something. The I can "git remote add" that and git can process things through "git cherry-pick" much better than applying .patch files. And it can do some 3-way difference calculations and...

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

    No, because they replace patches which are already included in letux-6.1-rc2. So the original ones were in the way. And the patch system uses line numbers to locate where to apply patch fragments ("hunks") to. If these are too far away it will simply give up. But I was able to write a script...

    Nice. I'll integrate into letux-6.1-rc2. If you agree I can also include the code for your user-space tool. It was just a little difficult to find out that it only merges cleanly with linux v5.9.

    OS on SD Card only booted once

    Ok, it looks as if your board may have different RAM chip setup parameters when booting from eMMC than on the SD card and therefore the U-Boot from SD does not properly initialize the RAM. This could explain why it worked once: you just were lucky. I am not sure what the solution for SD card...

    OS on SD Card only booted once

    Yes, that looks good. What do you see if you boot from the eMMC?

    OS on SD Card only booted once

    Can you connect some PC through an µUSB cable and run a terminal program to watch what the serial console is telling during boot?

    Slackware inside Pandora.

    No, no "tar". A bitwise image of the whole disk (SD card) not an archive of the files. Something like (assuming your SD card reader is /dev/sdb and the partitions are /dev/sdb1 etc. gzip </dev/sdb >image.gz The idea is to make a 100% clone of your SD card and try booting on a different device...

    Slackware inside Pandora.

    It is only the visible content in a SL4P-PHASE-2.tar.bz2 file. I.e. tar.bz2 format. Tar just collects all files into a single one. So it is not an .iso or .bin disk image which is better suited for trying to run exactly the same system on a different hardware and inspect the boot process.

    Slackware inside Pandora.

    Hi, nice. But that way it is unfortunately incomplete since it is just a tar archive of the root file system. Things may already go wrong during boot. Maybe you can simply gzip </dev/sdb >image.gz (i.e. the whole SD card) into some file and share? This allows to make a 1:1 copy of your card.

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

    GPADC_IN2 (audio accessory/general purpose) seems to be connected to GND throut a 0Ω resistor (R82)... GPADC_IN7 is called "VCC_SENSE". You probably could also try channel 10 which is VBUS and play with USB voltages...

    Minicom?

    0. minicom was already installed 1. there is no /dev/modem on your system 2. you obviously can't access /dev/ttyS0 as user - maybe you can try as root or find out who the owner of /dev/ttyS0 is and what the permissions are 3. you have to find the right device file name

    Hm. That sounds correct. Well, there seems to be issues with the 1GHz Pandora. Difficult to debug without either an 1GHz unit or a serial console...

    Are you interested in a new Pandora LCD cable?

    Well, I would be interested in an answer as well :)

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

    Maybe you could try to send I2C commands to the LED controllers and make them fancy blinking :) Or read out the Fuel Gauge chip. What I have no idea is how to prevent the kernel on the A15 cores from trying the same at the same moment...
