Re: RPI3 with initramfs built into kernel

... to make things more complicated I would like to use a fitImage with u-boot containing the kernel with built-in initramfs.
Does anybody have experiences with that ;-)

Re: RPI3 with initramfs built into kernel

Thanks, this works, however I meant using initramfs build into the kernel without an external image using the kernel config parameter INITRAMFS_SOURCE="xyz"

RPI3 with initramfs built into kernel

Has anyone ever managed to compile the initramfs into the kernel and get this running on a raspberry pi? I have been trying for days, but can't get it to work. It seems to only work with an external initramfs file. Is this correct, or is there a way to set kernel configs and bootargs to get it up an...

Re: Raspberry Pi 2 Custom Kernel with initramfs

could you explain how the boot-parameters have to be set with an internal (compiled into the kernel) initramfs?
I am trying since hours and don't seem to get which cmdline options need to be set...

Thanks for any hint!

RPI3 bluetooth Audio Sink not working

Hi, I have been using a RPI 2 as a bluetooth audio sink successfully for quite some time now. Today I tried the same setup with my new RPI3, however, the device only appears as a Telephony Service on my Android phone, although device class 0x20041C has been set. Is it possible that this is due to th...

Re: Experiment with Camera Module : MMAL, OpenCV, Overlay

Hello, I did download the repository and compiled it, but how do I start the software, e.g. the face recognition example?
I guess I'm too stupid...
Any example would be highly appreciated.

Thanks

Re: Serial Levels

Thanks Gordon, it works.
When doing the above cited gpio tests, I find that the pins seems to be functional.
BTW is the RX pin 10 or 15?

Thanks

Re: output webcam directly via hdmi on tv

Hello, streaming video using ffserver does work, however when I am starting the following command, all I receive is a green square on the tv:

mplayer tv:///dev/video0 -fps 10

I do have a logitec C270 webcam, if this information is of any interest.

Hallo, also wenn die Firmware mit apt-get update aktualisiert wird, dann ja. Ansonsten habe ich keinen extra Treiber für die Cam installiert, da diese direkt nach dem Einstecken erkannt wurde als video0 und funktioniert hat.

Hallo, ich habe eine Logitech HD Cam, die ohne weiteres Zutun sofort als video0 gefunden wurde. Wenn ich motion -s starte mit 2 fps starte, dann sehe ich ein paar Sekunden lang Updates über das Web-frontend, danach friert der RPi ein, ohne dass ich über ssh oder tty rebooten kann. Woran könnte das d...
