HDMI signal not detected

Sat Feb 21, 2015 5:44 am

I have tried one HDMI - HDMI cable and a HDMI - DViD cable from a Raspberry Pi with Arch Linux 2015 on the card. The monitor displays no signal or entering power mode in the latter case.

Do I have to configure a OS file on the SD card ?

Ssh into the pi with putty and do

Code: Select all

sudo nano /boot/config.txt
or put the sd card in a pc and find the config file.
Then increase hdmi signal to

Code: Select all

config_hdmi_boost=6
also uncomment

Code: Select all

hdmi_force_hotplug=1

I got the PI model B, B+ and PI 2 model B.
When will I get the A? I don't know.

Thanks for the prompt reply, expandables.
I have looked for the config.txt file on the 2015 ARCH linux version but this file was not present. I'm guessing it's called something else.

However I did find it on arch_linux 13 -06-2012 version.
I did try what you suggested but I still get No signal detected (when connecting HDMI to DVI) and NO cable detected (HDMI-HDMI). I even peeked at https://raw.githubusercontent.com/Evilp ... config.txt for some information however it wasn't of much help.

My config.txt file looks like
hdmi_force_hotplug=1
hdmi_drive=2
config_hdmi_boost=6

Initially though it contained all these commented sections in one single line(when i first installed the OS on the flash). I assumed that each desired line has to be on its one uncommented line right. I modified the config.txt file in Windows.

Which Raspberry Pi Model do you have? Arch has different installations for the older models vs. Raspberry Pi 2, make sure you have the right tar file.

The monitor is self-powered? If not, that could be a contributing issue.

Model B+. Im trying to follow these steps http://www.instructables.com/id/Raspber ... tion-Syst/ so that I can ultimately get an IDS on the Pi.

The monitors were powered through AC cables.

ArchLinuxArm for the B+ is here http://archlinuxarm.org/platforms/armv6/raspberry-pi the developers do not provide .IMG files any more

If you need an .IMG file see http://downloads.raspberrypi.org/arch/i ... 2014-06-22 this was the last one released by the developers suitable for the B+

Thanks for your help.

I have tried the images you provided however I still encountered similar issues.
I did found a workaround by using NOOBs. As we speak I do have a functional Arch OS on my Pi however its not the version I wanted. More questions might follow so stay tuned for the next episode :D

There are only two versions of Arch Linux Arm, ARMv6 for A/B/A+/B+ and ARMv7 Pi2 B

Arch is a roling release so has no revisions just always up-to-date by running:

Code: Select all

pacman -Syu

Indeed. I did update it and had to google some other commands and workarounds for installing SNORT. It seems to be installing for the past half hour so I think I'm on the right track. Tomorrow I will need to test it and if it works properly I will then have to work on a anomaly detection plugin to implement in Snort. As I said stay tuned :lol:
