LTDC display issue on STM32H753 eval board

[Gpeti]

I'm starting a bare-metal firmware that will display basic graphics on a LTDC connected LCD screen. For the moment I'm using a STM32H53-EVAL2 board (rev E I think)

Right now I write a fix image in the frame buffer. The image is correctly displayed except it's kind of blinking.

Since the image never changes I suspect it is due to the setup of the LTDC interface or LCD screen.

I based my software on STM32CubeH7 source code example (LTDC_Paint application).

Do you know:

- the screen model on the eval board ( I couldn't find the model in the STM32H753-EVAL2 reference manual)

- what configuration parameter could cause the "blinking" of a fixed image ?

Thank you

From the board user manual UM2198 page 57:

AMPIRE LCD panel: AM640480G5TNQW-T00H or AM-640480GFTNQW-T07H-A

Thank you, my LCD clock setting was wrong.
