Part Number: LAUNCHXL-F280049C
Other Parts Discussed in Thread: SFRA
Dear TI Team,
I am working on as project related to digital buck boost converter. I believe I configured the CMD file correctly as I can generate the code by combining the FLASH BANKS 8 9 10 11 (FLASH_BANK0_SEC8_9_10_11). Before combining them to one I was receving linker error cuz of no space to fit in code.
Now the issue is during initialisation inside main block upon entering DCL_setup() and just when trying to execute BUCK_ DCL_UPDATE(&BUCK_ctrl); I am having ITRAP handler executing in loop.
Could you please help me in finding the cause of this issue. My flash.cmd file is as follows. I am using Lauchpad_F280049C
