Atmel SAM3X dual bank switching not working

问题 I'm currently working with an Atmel SAM3X8 ARM microcontroller that features a dual banked 2 x 256KB flash memory. I'm trying to implement a firmware update feature, that puts the new firmware into the currently unused flash bank, and when done swaps the banks using the flash remapping to run the new firmware. The datasheet states to do so I need to set the GPNVM2 bit, then the MCU will remap the memory, so Flash 1 is now at 0x80000 and Flash 0 at 0xC0000. This will also lead to the MCU

Atmel SAM3X8E dual bank switching for booting different behaviour

I’m currently working with an Arduino Due board which has an Atmel SAM3X8E processor embedded. I’m programming it using the Atmel Studio (version 7.0.1645) and the provided Atmel Software Framework (version 3.28.1). The purpose of the program running on the SAM is to gain reprogramming functionality. Therefore the program gets the image from a host PC, flashes it block by block in the unused flash bank and verifies the image. All that is working fine, but I’m running into the same issue as this post ( Atmel SAM3X dual bank switching not working ). The Atmel SAM3X8E has two 256-kByte flash
