Can stm32f429 control emmc (5.1) E.g SDINBDG4-16G?

stm32f429 Internal peripherals mmc 4.2,but present emmc 5.1。

Is it a fully compatible driver?

Is there a ready-made example?

A workable subset of functionality could be achieved, limited by the pins and clocking methods.

A demo for this platform/parts combination could be created. More of a built-to-order process.

Yes, it can control eMMC.

When a new eMMC version rolls out, the difference is usually additional commands/features but things stay generally backwards compatible as existing features do not change.

The HAL driver for eMMC leaves something to be desired. No direct examples for eMMC that I know of. Expect to spend some time developing it yourself or paying someone else.

Is it better for me to use stm32h743 to control emmc (5.1)?

It should be about the same, although the HAL driver may be slightly different between the two based on the current development state.
When I was using it a year ago, the H7 driver had more functionality. I would not be surprised if the F4 driver has caught up by now.
