I developed a new stm32mp157 board. Do I need to update the firmware to run A7 on stm32mp157? Or is the firmware already updated?

I'm talking about the stm32mp157fac chip.

 

Do users need to separately upload firmware to run the A7 core?

Or, I would like to know if it was already done at the time of production.

 

I created the circuit and artwork to match the stm32mp157 discovery board.

STM32MP15x MPUs does not come with an embedded flash memory, that is why you need to incorporate uSD card, eMMC or NAND/NOR flash on your custom board.

Only basic boot functionalities are integrated by ST inside the chip, the rest of the boot sequence and user application must be flashed on an external memory, such as the uSD card you can find in discovery kits.
