Hello,
I have a question about the usage of the MCE in the STM32H7RS
I have the STM32H7S78-DK board
I'm starting with a project that show images to LTDC with images on the flash (copy with DMA2D) and the framebuffer is on the PSRAM.
My project works with this tuto to get the flash running : https://github.com/ST-TOMAS-Workshop/stm32h7s_workshop/tree/main/1_external_memory
And this one to have MCE working : https://github.com/ST-TOMAS-Workshop/stm32h7s_workshop/tree/main/3_external_memory_encryption
The project seems to run well beacause my led blink like it should but !
defining my images in "const uint16_t ecran_start" now (since MCE is enable) gives me black images (in debug session i see the variable in Expressions correctly) .
Removing the const the images shows but by internal ram will be filled very quick
Putting the image in my PSRAM section it is glitched on the screen
My framebuffer is in PSRAM and works because DMA2D show a red rectangle that i programmed (DMA2D R2M)
Putting framebuffer into internal RAM doesn't fix issues
Is there special things to setup about memory usage with MCE ?
Thanks
