This code example writes custom bytes to the Gang Write Buffers (6) within the API-DLL, programs the buffers to targets' flash, and then verifies the programmed data using direct read-back of the targets' flash. This example is geared towards multiple targets GangPro-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 devices and open communication using F_Open_Target_Device

• The return value is a TRUE MASK (0x01..0x3F) : 0x01 - target 1, 0x02 - target 2, 0x04 - target 3, 0x08 - target
  4, 0x10 - target 5, 0x20 - target 6, if at least one target succeeded then proceed further.

• 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 Gang Write Buffer for target 1 with custom bytes starting at address addr using F_Put_Byte_to_Gang_Buffer. The user can change the first parameter to write different bytes to target 2, 3, 4, 5, or 6.

• Program custom bytes to targets using F_Copy_Gang_Buffer_to_Flash

• Read target memories and save contents to Gang Read Buffers (6) using F_Copy_Flash_to_Gang_Buffer

• In a loop, read bytes from the Gang Read Buffers and print them using F_Get_Byte_from_Gang_Buffer, this example iterates over 6 target buffers.

• Power down targets and close communication using F_Close_Target_Device
