HITMIK commented 2 years ago

Hi,

i have samsung and rpi4 with newest rpi-firmware. On kodi not work cec.

I try unpluge samsung and rpi4 power on 10 minutes.

Any solution?

popcornmix commented 2 years ago

I assume you ran rpi-update? Was cec working before you ran it?

HITMIK commented 2 years ago

Yes, cec ran. But i dont know since when cec dont work (how version crash it). Maybe problem with raspberry firmware? Maybe your fw is OK.

popcornmix commented 2 years ago

Sorry, you've not provided enough information for any useful support. Please explain exactly what sdcard image you are running and if CEC previous ran, what happened to stop it working (e.g. did you upgrade any software).

Hello! I can confirm that - hdmi-cec does not work with "fresh" firmware.

For test, i done some checks on fw versions:

I. hdmi-cec not working on: Linux raspi 5.10.52-v7l+ #1440 SMP Tue Jul 27 09:55:21 BST 2021 armv7l GNU/Linux Linux raspi 5.10.50-v7l+ #1437 SMP Thu Jul 15 11:48:49 BST 2021 armv7l GNU/Linux Linux raspi 5.10.49-v7l+ #1436 SMP Wed Jul 14 14:18:38 BST 2021 armv7l GNU/Linux

II. hdmi-cec working correctly on: Linux raspi 5.10.46-v7l+ #1430 SMP Mon Jun 28 17:14:36 BST 2021 armv7l GNU/Linux

All test was made on one TV/cables etc. HDMI-CEC functionality was tested on kodi 18.7 My raspi:

Thanks that helps. I assume you are using the fkms driver? Can you confirm if https://github.com/Hexxeh/rpi-firmware/commit/9dbcd6dfed16cc7de4a67b9ca445c4847f68c4c2 is working or not?

I assume you are using the fkms driver?

root@raspi:/home/pi# cat /boot/config.txt | grep fkms

9dbcd6d No, on this commit hdmi-cec not working.

HITMIK commented 2 years ago

Yes men!

On "Linux raspi 5.10.46-v7l+ #1430 SMP Mon Jun 28 17:14:36 BST 2021 armv7l GNU/Linux" HDMI-CEC WORKS!

popcornmix commented 2 years ago

Can you test with lastest rpi-update firmware which has a potential fix.

e-losin commented 2 years ago

With commit ce56fb43ea36888b94026edd1f08aea78cf32262 it works! Thank you!
