I set up the dt-blob.bin with the electrical references and created a custom overlay to make my display work with the specific timing parameters. When I ran commands like dmesg, modetest, gpiotest, etc., all the configurations appeared to be recognized by the system. However, there is no graphical interface showing up on my screen — only the backlight is enabled.
What could be the issue?
OBS.: The base board has a 1.8 V regulator activated, so I didn't apply a power supply.
