Other Parts Discussed in Thread: UNIFLASH, HALCOGEN
Hi…,
We are developing a boot loader for TMS470MF06607 controller. We are using the example boot loader program from TI developed by Mr.QJWang.
The boot loader is able to flash the application code to the designated Flash memory. We have confirmed this by reading the memory form controller using UniFlash software at boot loader address at 0x000 and application address at 0x8000. But after flashing when we try to run the application code it’s not running.
We need support to confirm whether we have done the memory mapping properly in the application program. I have attached the images of the memory map that we have done. We followed the application note SPNA200–September 2013 - CAN Bus Bootloader for TMS470M MCU for memory mapping of application program.
The application has to reside in the Sector 2 of Flash Bank0 @ 0x8000 address
Below is the Application Program Memory mapping:

-l rtsv7M3_T_be_eabi.lib
--retain="*(.intvecs)"
/* USER CODE BEGIN (1) */
/* USER CODE END */
