isn't it sufficient to use vc4-kms-vga666 overlay for Pi2Scart?
Code:
Name: vc4-kms-vga666Info: Enable the VGA666 (resistor ladder DAC) for the vc4-kms-v3d driver. Requires vc4-kms-v3d to be loaded.Load: dtoverlay=vc4-kms-vga666,<param>Params: ddc Enables GPIOs 0&1 as the I2C to read the EDID from the display. NB These are NOT 5V tolerant GPIOs, therefore level shifters are required.Statistics: Posted by aBUGSworstnightmare — Sat Nov 22, 2025 6:21 am
