Best Stratégie for stm32h743ii for flash memory management LVGL

[KNaim.1]

Dear All,

I have dev a custom  pcb based on stm32h743ii series with the following Spec:

Flash :  25Q256JVEN

SDRAM: W9825G6KH-6

lcd wiki 7 inches resolution 1024 x 600

What i have configure  ltdc on sdram at adress 0xC0000000 is ok .

Now is the configuration of the flash do i have to make 2 partitions on the flash on cube mx config to use lvgl and dma.( i need a general buffer for sensor data).

or make just one and make a bootloader  with memory mapped mode i really lost.

I have download lvgl source file is 20Mo so it's 184 Mégabits it will left me just 72Mégabits for fonts and images.

if some one be kind to give me the best config and some advise to light lvgl that would be cool

Hello @KNaim.1, 

For your STM32H743II project, I'd recommend using a single partition with memory-mapped mode for the flash. This approach simplifies accessing large assets needed by LVGL. A bootloader would be helpful for managing firmware updates.

Also, you might want to ask for advice on the LVGL forum
