Hello,

I found this PR.
https://github.com/micropython/micropython/pull/3940

I will try to this my STM32F746G-Discovery board.
But SDRAM works lower than 200MHz on STM32F746G-Disco.
Is there any problem SYSCLK will be down in "mpconfigboard.h"

Otherwise, should I change the clock after judging the validity of SDRAM?

Hi,

I defined pins about SDRAM, and I built firmware.
I think SDRAM initialization is done.

But at gc.collect(), firmware freeezes.

My test source for SDRAM will be found here:
https://github.com/forester3/micropytho ... disc-sdram

I finished PR to supprort SDRAM on STM32F746G-Discovery.
