Writing to a flash sector while starting the erase of other sector have a undefined behavior so lets add a semaphore and syncronize access to Flash registers. But for the semaphore to work it needs to be initialized so each board needs call stm32_flash_initialize() on initialization, so to avoid runtime problems it is only using semaphore and making it thread safe if initialized, after all boards starts to call stm32_flash_initialize() we can remove the boolean and the check. |
