Hi Patrick,
Add weak callback to allow board specific behavior
- flush
- initiated
This patch prepare usage of DFU back end for communication with STM32CubeProgrammer on stm32mp1 platform with stm32prog command.
Would the stm32prog need to modify the environment variables ? For example to update the "VERSION" or any other one?
