DavidMF Posted February 26 Posted February 26 Hi there. First time posting. I already installed the latest version of the desktop version for my M1 and I was gratefully surprised how an old device is still working thanks to the armbian community. Thanks all of you. I am on a retro project trying to make my M1 working on an old crt TV through the pal/ntsc video output. New compiled kernel doesn’t seem to have the necessary driver/module. Any workarounds/ideas to achieve that? thanks 0 Quote

My M1 is unused at the moment, I will connect some SATA disk soon, but I don't know If I still have working composite video, that is a problem. I don't have a TV, maybe a USB recording device with composite imput I have somewhere in a paperbox can be use. 0 Quote
Ryzer Posted February 27 Posted February 27 Hi David, Can you check that sun4i-a10-tv-encoder module is present with lsmod? If it is then you will probably need to edit the device tree to include the TV display nodes, the bindings can be found here: https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/Documentation/devicetree/bindings/display/allwinner,sun4i-a10-tv-encoder.yaml?h=v6.12.17 If not you can try to build the module if you have headers installed. Unfortunately I don't know the status of tv output support so there is a possibility even carrying out each of these steps that it may not. Best of luck Ryzer 0 Quote
robertoj Posted February 28 Posted February 28 Is the A10's TV encoder much different from the H3 TV encoder? The orange pi zero LTS has a working TV-out in Armbian (at least when I tried it last year) 0 Quote
Ryzer Posted March 1 Posted March 1 @robertoj In terms of the actual TV encoder itself not significantly different, the same TV encoder driver is used for the H3. It just parses a different compatibility string to address any differences. If it still works on a device like the Orange Pi Zero then that is strong indicator that it is likely to work on the Banana Pi M1 Another thing to be mindful of is that the TV encoder is only part of the Display Engine. The A10 and A20 (which is the SOC on the Banana Pi M1) both have the 1st generation Display Engine where as the H3 is based on the 2nd generation. 1 Quote
DavidMF Posted March 20 Author Posted March 20 Thank you all for your ideas,. I’m considering to acquire a cheap hdmi to to video converter and only readjust the resolution to match the 4:3 ratio. It would be enough for me. best regards David 0 Quote
Ryzer Posted March 20 Posted March 20 HI David, Probably the easiest way to it. I can confirm by my Pcduino3 that Hdmi at least works although only with current (tested with 6.6.75) for the moment. I found that while the components are correctly enabled in edge (tested with 6.12.9) hdmi fails due to some a fault with the "hdmi-connector" component of the drm driver. all the best Ryzer 0 Quote
