Yes, the sdram model informs this value, but in the project it is around 90Mhz (180/2). In the second question, I tried to lower the pixel clock to 16Mhz and the problem is gone and in touchGFX too. Now is it possible to solve the problem without low...

Thanks for the answer. The frame buffer is in external SDRAM at 166mhz, connected to the FMC along with the NOR flash. The bus width and color depth are 16 bits. Pixel clock is 25MHz with 55hz display. The stm32f429 is at 180mhz and the DMA2D on the ...

Thank for answer. I need a file with format .stldr for stmcubeIDE, correct? I can already write, read and erase the flash memory in my code, but how do I create this file for the external loader?
