[IDEA] Include moodecfg.txt on ISO

[audiophonics]

Ok understood... the I2S selection use this sed command :

Code:

    sysCmd('sed -i /dtoverlay/d ' . '/boot/config.txt');

Which erase any dtoverlay setting that is not integrated into moode.

I noticed that when trying to use power control overlays :

Code:

dtoverlay=gpio-poweroff,gpiopin=22,active_low
dtoverlay=gpio-shutdown,gpio_pin=17,active_low=0,gpio_pull=down

But I understand you can't do a more precise filter, as after overlays there is the DAC name.
So we did a workaround using python.

Are these for a particular audio device in moOde's I2S list? If they are it would be easy for me to add the lines to the PHP function.

No there are kernel overlays to manage RPI behavior. gpio-shutdown make the RPI go standby when it's activated.
It was to ease the use of our power manager board, but we finally made a python script that work even better.

This made me think the whole file was overwritten, but I was wrong, it's only "dtoverlay" lines.

Hi,

I raised the issue here Foreign overlays deleted by Moode !
which Tim answered nicely !

Yes, I'll add to the 7.1.0 TODO list.

[Tim Curtis]

After looking at the code this morning I'm not sure how to surgically remove/replace just the overlay for an i2s device.

Maybe add something like below at the end of the file

Code:

#---------------------------
# CUSTOM OVERLAYS AFTER HERE
#---------------------------

And someone with better sed skills then me to remove lines with dtoverlay lines until line with CUSTOM or end of file is found 

[Tim Curtis]

A SED guru is needed.

Maybe this:

Code:

sed '0,/^dtoverlay=/{/^dtoverlay=/d}' /boot/config.txt

It will remove only the first line with dtoverlay=
So if you keep all the custom dtoverlay after the dtoverlay from device, it should be good.

Before:

Code:

disable_splash=1
disable_overscan=1
hdmi_drive=2
hdmi_blanking=1
hdmi_force_edid_audio=1
hdmi_force_hotplug=1
hdmi_group=0
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=off
dtoverlay=i-sabre-q2m
#dtoverlay=disable-wifi
#dtoverlay=disable-bt
dtparam=spi=on
arm_freq=1000
sdram_freq=500
core_freq=400
gpu_freq=300
arm_64bit=1

#---------------------------
# CUSTOM OVERLAYS AFTER HERE
#---------------------------

dtoverlay=gpio-ir,gpio_pin=4

After:

Code:

disable_splash=1
disable_overscan=1
hdmi_drive=2
hdmi_blanking=1
hdmi_force_edid_audio=1
hdmi_force_hotplug=1
hdmi_group=0
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=off
#dtoverlay=disable-wifi
#dtoverlay=disable-bt
dtparam=spi=on
arm_freq=1000
sdram_freq=500
core_freq=400
gpu_freq=300
arm_64bit=1

#---------------------------
# CUSTOM OVERLAYS AFTER HERE
#---------------------------

dtoverlay=gpio-ir,gpio_pin=4

[Tim Curtis]

Nice. I'll use that approach :-)

[TookaFace]

Better way:

Code:

sed '0,/^dtoverlay=/s/.*dtoverlay=.*/dtoverlay=test/' /boot/config.txt

It will directly replace the first line only which begin by "dtoverlay=" with "dtoverlay=test" (the new i2s device).
