Does nandflash and EMMC of stm32mp157c share the same interface or independent interface?

Hello,

You could find detail information in Documentations (Reference Manual, DataSheet), Application Note (AN5031) or Wiki (e.g. https://wiki.st.com/stm32mpu/wiki/STM32MP15_ROM_code_overview)

To sum-up, we are able to connect simultaneously many interface, if package pin count and your pinout usage allow it (your could quickly test using STM32CubeMx).

e.g. a typical usage similar to STM32MP157C-EV1 board

  • SD-Card 4-bits on SDMMC1
  • eMMC 8-bits on SDMMC2
  • Serial-NOR 4-bits and/or Serial-NAND 4-bits on QUADSPI
  • SLC-NAND 8 or 16-bits on FMC
