PAL-M or NTSC-J on Raspberry Pi-5

Hey Guys, I've got an issue. For some reason I can't set my Raspberry Pi-5 to ntsc-j, pal-N, Pal-M etc. Only Ntsc & Pal. I have the latest version of libreelec and have tried this with other os such as raspian. Nothing. I have set

dtoverlay=vc4-kms-v3d,composite

AND

enable_tvout=1

with and without

sdtv_mode=1
sdtv_aspect=1

and have set cmdline to either

video=Composite-1:720x480i,vc4.tv_norm=NTSC-J

or

video=Composite-1:720x480i,tv_mode=NTSC-J

as mentioned here: https://forums.raspberrypi.com/viewtopic.php?t=364251 but nothing! Only basic us ntsc of British pal. Can anyone here help me with this? What do I need to do to set this to ntsc-j, pal-m or pal-N for the Raspberry Pi-5?

Just to be sure, you have changed these files?

/boot/firmware/cmdline.txt
/boot/firmware/config.txt

yes

https://www.raspberrypi.com/documentation/computers/config_txt.html

libreelec has config_composite.txt I have set them too

That is the procedure in the official doc

yes follewed them exactly. Nothing

Ok, then Im out...

do you think it will work on an older os?

No, older OS doesn't have drivers for Raspberry Pi 5 hardware

dam. I know the pi5 doesn't use vec, it uses rp1 instead. From what I looked into when looking through the githib, there is no secam support for rp1 driver. But there is for ntsc-j, pal-m etc. So I don't know if I have to set it so something like

rp1.tv_mode=NTSC-J

or something.

The supported formats, copied from the official doc is: NTSC, NTSC-J, NTSC-443, PAL, PAL-M, PAL-N, PAL60 or SECAM.

isn't that for vec driver only? Not rp1?

because from my research the pi5 uses rp1 for its composite output, not vc4

The official doc hasn't made any differences between those two, perhaps a bug ? I haven't compared RP1 and CV4 against the doc, I have blindly relied on the doc...

yeah, the devs stated don't use vc4.tv_norm=NTSC-J in the docs. They got rid of it. Now its apparently tv_mode=NTSC-J. So the docs are probably the worst place for info regarding anything to do with composite on the Rapsberry Pi-5.

Thats true, on of the changes that make old Raspberry Pi OS useless on Pi5
