Data signal for LCD (LTDC) not generated

[ldanu]

Hi, Currently I'm programming STM32H743 for application which is using LCD TFT Controller. I'm using custom board. All RGB data signal not generated but other signal generated for example LCD clock signal, VSYNC, HSYNC.

Anyone know how to solve?

Check if those pins work at all, setting them as GPIO outputs and toggle them "manually". Then in the "real program" read out the related GPIO registers and check their content.
