Segmentation fault - raspberry 4 #577

Closed sfoglia closed 2 years ago

sfoglia commented 2 years ago

Basicaly I'm trying to debug why kodi cec support seems to not work anymore with my TV and ended here.

HW: raspberry pi 4 4GB SW: raspberry pi os

Linux PItv 5.10.52-v7l+ #1440 SMP Tue Jul 27 09:55:21 BST 2021 armv7l GNU/Linux

I've followed: libcec/README.raspberrypi.md at master · Pulse-Eight/libcec · GitHub


    sudo apt-get update
    sudo apt-get install cmake libudev-dev libxrandr-dev python3-dev swig git
    cd
    git clone https://github.com/Pulse-Eight/platform.git
    mkdir platform/build
    cd platform/build
    cmake ..
    make
    sudo make install
    cd
    git clone https://github.com/Pulse-Eight/libcec.git
    mkdir libcec/build
    cd libcec/build
    cmake -DRPI_INCLUDE_DIR=/opt/vc/include -DRPI_LIB_DIR=/opt/vc/lib ..
    make -j4
    sudo make install
    sudo ldconfig
    sudo reboot

Now if I start: sudo cec-client -t p result in:

Found out this note:

warning not compatible with Kodi 18.x. Please use libCEC 4.0.7 instead.

So I've recompiled, this version doesn't trow the Segmentation error but get stuck and from kodi still no control is available: https://github.com/Pulse-Eight/libcec/releases/tag/libcec-4.0.7

Could be this: https://github.com/Hexxeh/rpi-firmware/issues/267 The firmware should be appear in apt imminently.

sfoglia commented 2 years ago

that's it now I've run the rpi-update and with libcec 4.0.7 is working again.
