Panasonic Viera TH-50PX600A - Power On does not work

[heitbaum]

Could you please assist in sharing the CEC code that will allow the TV to power on / identify why lib CEC is not successful in powering this device on using hex 04.

The following trace (From the NUC $8) shows the AppleTV $4 which became the active source when I used the Apple remote. Trying to turn the TV on. And it always errors. The second trace shows the cec-client trying to turn the TV on. Same issue - with “feature abort”

Standby 0 works fine.

I tried other codes whilst in standby mode (http://www.cec-o-matic.com/) with no success.

The manual indicates it works. But without another Panasonic device - I can’t validate... https://www.manualslib.com/manual/118537/Panasonic-Viera-Th-42px600a.html?page=17#manual

So on much searching and testing. The code required to power on the Panasonic is the same as the AMP. In my case: (Playback 2 —> TV) 80:44:40 80:45

So the question now is, how can libcec be updated to run this CEC to their TV?

CEC bus information

device #0: TV address: 0.0.0.0 active source: no vendor: Panasonic osd string: TV CEC version: unknown power status: on language: eng

ver 0 CEC version unknown DEBUG: [ 3317615] 'get cec version' is marked as unsupported feature for device 'TV' ven 0 vendor id: 008045

What would be required to add functionality to kodi CECBuiltins.cpp to enable access directly to CEC-client XD)

I have been testing with the kernel cec driver. Compile the kernel with the CONFIG_USB_PULSE8_CEC=m

Then run

modprobe -v pulse8_cec /storage/inputattach --pulse8-cec /dev/ttyACM0 --daemon cec-ctl -playback

OFF

`cec-ctl --standby -t0

ON

cec-ctl --custom-command=cmd=0x44,payload=0x40 -t0 cec-ctl --custom-command=cmd=0x45 -t0

This was tested with linuxconsole tools - Release 1.7.0 https://sourceforge.net/projects/linuxconsole/ git clone https://git.code.sf.net/p/linuxconsole/code linuxconsole-code

Kernel: 5.9.0 x86_64 GNU/Linux

trying to work out how to use cec with kernel on raspberry pi. The branch 5.9 can control the second HDMI port via cec however I have not been able to get it working.

The was a vague comment left on a forum which said you can only use the kernel to control the second hdmi port via cec - however I have absolutely no clue on what settings are required.

Is the above the only "flag" i need to add ? "CONFIG_USB_PULSE8_CEC=m"

I am working with the version 6.0 if cec and there are some flags one puts in - I am presuming I just ad this ? So delete everything, download it and ad this flag ?

Sorry for being vague - general new guy here.

@audas have a look at my changes to the kernel configuration (as contained in this commit) note: this is for the generic Pulse8 USB adapter.

Ok thanks - way above my skill set. I will see if I can figure it out. Wish me luck.
