Cloning (saving) sd card to a file for later flashing back to sd card

[hritter]

I have an STM32MP157F-DK2. I am wanting to save the original contents of the sd card. How do I save the sd card to a file that I may later put it back unto the sd card? Will dd do this?

Thank you!

Hi @hritter ,

Original content of the SDCard is the Starter Package image which is available on st.com. Refer to Getting started - stm32mpu
