I have been trying to get lxqt (openbox) to run in the monitor native 2560x1440 but it seems confined to only 1 low resolution of 576p. Seems like other standard resolutions such as 1920x1080 for example should be supported. I'm wondering if I am missing some driver? Note that I had to install xf86-...

I have a RPi4B 4G model that suffers from an inability to boot (randomly it seems, sometimes it's fine other times what I go on to describe occurs). Upon attempting to boot, the following is displayed in an infinite loop, and no further initialization is possible: invalid bus width mmc0: error -22 w...

Take a copy of Raspbian, boot it, “modprobe configs”, “zcat /proc/config.gz”

Thanks you, will try it as soon as my hardware arrives. Is any running a Pi4 and Raspbian able to post that output in the meantime?

graysky

Can someone point me to something that details which kernel options are needed to get the Raspberry Pi 4 to boot and run properly? My goal is to have Arch ARM armv7h running on it. For reference, here is the base config file for that kernel.

graysky

@neilgl - Thanks for the ouput!
@jahboater - Agreed. -mfpu should no be simple vfp I would think. For RPi3B+ I use the setting you recommended. For example: https://github.com/graysky2/kodi-raspbe ... -pi4.patch

graysky

Would someone who has a Pi4 post the output of the following:

Code: Select all

lscpu

Code: Select all

uname -a

and

Code: Select all

gcc -c -Q -march=native --help=target

and

Code: Select all

gcc --version

Thanks!

Another option would be Arch Linux.

To be clear, Arch Linux != Arch ARM. For the Pie you want Arch ARM.

Can I get the latest default config.txt file ?

I think different distros ship different config.txt contents. For example, on Arch ARM, see this config.txt.

..which distro are you using?

graysky

I have a RPi3B+ running Arch ARM armv7h (or interesting aarch64 as well) and am experiencing lockups when copying files from an NFS share to the same NFS share. For example: rsync -a --delete-after -W -x -q /scratch/armc8/root/ /scratch/armc8/facade If I tail dmesg: [ +0.000005] nfs: server ease.lan...

Provide a cross platform stress test. Systester does this for x86_64 and i686 but not for ARM unfortunately (the purpose of this thread). If CalcPi is multithreaded, it satisfies all the criteria... if I could compile it that is

graysky

Thanks for the tip. I believe that is not multiple threaded, no? Do you know if CalcPi is? That is what I would like compile but am thus far unable.

graysky

I have no idea what systester is. If your plan is to compute digits of PI use gmp-chudnovski https://gmplib.org/pi-with-gmp.html https://github.com/natmchugh/pi/blob/master/gmp-chudnovsky.c http://calcpi.sourceforge.net/docs.html Worked very well on the Pi last time I tried it on Pi Day. How many b...

graysky

Definitely over my head :/

graysky

Thank you! I updated the Arch wiki accordingly.

graysky

I found this which suggests that adding 'dtparam=audio=on' to /boot/config.txt will remedy this situation which indeed it does... why is it necessary I guess is my question after running under the 4.1.x series without it?

On a Raspberry Pi 2 running Arch ARM, upon updating the kernel to the distro-provided linux-raspberrypi-4.4.7-1 package, running amixer results in the following error: % amixer amixer: Mixer attach default error: No such file or directory I believe this is due to some change in the way the snd-bcm28...

graysky

What distro? At what point during the boot process are you prompted?

EDIT: You mean it successfully boots and asks you to login?

graysky

Thought so thanks!

Does the tightvnc package supply x0vncserver? If so:

Systester is a program that can calculate digits of pi under linux. It hasn't been updated since 2012 unfortunately and it throws errors when compiling on my RPi2 yet interestingly, the cli version of the software does in fact build an executable that runs. Can anyone with knowledge take a look at ...

I have an RPi2 connected via HDMI to an HDTV. My goal is to use cec-client to query the TV to determine the on/off status of it (not turn it on or off but just query the status)... I can't figure out how to accomplish this. I added my user to the lock and uucp groups. As I understand the following o...

In Raspbian OS https://www.raspberrypi.org/documentation/configuration/audio-config.md That is the winning answer (it works under Arch as well). Thanks! What's interesting is that I can specify any value for the last digit (1, 2, 3) and the external speakers are selected. Any insights into that? % ...

I am attempting to have an HDTV hooked-up to a RPi2 via HDMI and keep external speakers hooked up to the 3.5mm jack. I am unable to output sound from the CLI to the speakers; all attempts go through the HDMI and out the TV. 1) I know the speakers work because I can have kodi output to them or to the...

If the modules are the same on each build perhaps the problem lies in the differences in versioning of wpa_supplicant. What version does Raspbian run?
