Discussion - EVE / Re: load data to external flash of riverdi board through stm32

As for the larger image not loading, it sounds like you are hitting the throughput limitation of the flash SPI interface for the IC, there is a limit on the amount of data which can be red during one screen refresh from flash. You could try lowering the screen refresh rate or utilising Adaptive Frame Rate to see if this helps with the larger images.
This problem fixed.It's about EVE_config library. I don't know why EVE_DISP_PCLK_FREQ is set 0xd12 !!!(In other library is 51MHz)
I changed it to 51000000 , EVE_DISP_PCLK to 20 , EVE_DISP_HCYCLE to 2000 so loading image directly from flash work properly.
I still don't understand why. Is there an explanation for this?
