Custom Buffer Write and Verify - FlashPro-ARM
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 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
usingF_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
