After update to firmware from stable branch composite output on Pi0W isn't work.

My settings:

# uncomment for composite PAL
sdtv_mode=2
#sdtv_aspect=3
#sdtv_progressive_scan=1
#sdtv_aspect=4:3
#framebuffer_width=960
#framebuffer_height=468

framebuffer_width=480
framebuffer_height=272

#sdtv_mode=1
sdtv_aspect=3

Return to the latest version from May fixes the problem. Kernel 4.19.50 with May firmware working fine.

Could you check the output of vcgencmd get_config enable_tvout?
If it returns 0 (it shouldn't) then you should be able to enable it by adding enable_tvout=1 to /boot/config.txt. Please then confirm the revision code for you Pi0W from /proc/cpuinfo?

Composite out is disabled by default on the Pi4, but it's just possible that that disable has managed to apply to other models.

On a RPi3B+
$ vcgencmd get_config enable_tvout
enable_tvout is unknown
pi@raspberrypi:~ $

enable_tvout=1 to /boot/config.txt. did not help.

Apologies - I was forgetting that we currently have two different firmware trees. Pi 0-3 won't have that option.
There is only one commit that touches really display, so I'll have a closer look.

We just bumped into this with RetroPie 4.5 release. We had manually updated to buster firmware/kernel packages (since the last Stretch kernel had another issue that broke sony bluetooth devices).

We would be hugely appreciative of a kernel/firmware package update for Stretch that includes this. Happy to send bribes/cake/beer etc :-) . Thanks as always for all your efforts.

If no errors appeared, your firmware was successfully updated to 7918aa035dd6529f32d242775dd0e3ca6c5bf3d3

Fixed for me this issue.
