This code example writes custom bytes to the Write Buffer within the API-DLL, programs the buffer to target flash, and then verifies the programmed data using direct read-back of the target’s flash. This example is geared towards the single target FlashPro-ARM M library.

The condition for this example to work properly is that F_OpenInstancesAndFPAs, and F_Initialization has correctly initialized the given fpa index (1 to 64). If testing adapter 1, the user should call F_Set_FPA_index(1) before this code executes. In addition the user should load the intended configuration file using F_ConfigFileLoad so that the right MCU is selected.

MCU_Info struct was initialized using example Get MCU Info.

The code sequence is as follows:

• Power on target device and open communication using F_Open_Target_Device

• Get MCU base flash address, MCU_Info.u.x.FlashStartAddr, and add 0x100. This code will write custom bytes to almost the start of flash.

• In a loop, populate the Write Buffer with custom bytes starting at address addr using F_Put_Byte_to_Buffer

• Program custom bytes to target using F_Copy_Buffer_to_Flash

• Read target memory and save contents to Read Data Buffer using F_Copy_Flash_to_Buffer

• In a loop, read bytes from the Read Data Buffer and print them using F_Get_Byte_from_Buffer

• Power down target and close communication using F_Close_Target_Device
