Could the STM32F103 or STM32F412 support 4GB eMMC nand flash?

Our project want to use the 4GB eMMC NAND Flash on STM32F103RC or STM32F412VE.

The eMMC architecture of NAND flash support revision , below. It just require to over the MMC standard 4.41 / 5.1.

Both of them have the hardware to support 4GB eMMC. The HAL support may not be complete. Last I checked the F4 only supported up to 2GB.

Yes, both F1 and F4 should be capable of accessing an eMMC device. You'll be responsible for implementing the driver.
