=== Flash uSD with STM32CubeProgrammer ===
Another way is to use the [https://www.st.com/en/development-tools/stm32cubeprog.html STM32CubeProgrammer] tool, which has a little different approach than BalenaEtcher. STM32CubeProgrammer makes use of several files generated by Yocto. For the sake of simplicity, the following procedure shows how to run it on the MVM so that it can access these files directly. Please note that, by default, STM32CubeProgrammer is not installed in the MVM. Please refer to the STM documentation for installation instructions.
* Execute First of all, execute the build with yocto, see Yocto to generate the required files. See [[DESK-MP1-L/Development/Building_the_Yocto_BSP | here]] for more info.
