Other Parts Discussed in Thread: C2000WARE
Hello - i am working with the Flash API routines and am running into issues when i change compiler optimization to level 2 (global optimizations).
My program works fine when optimization is set to off or 0 or 1...it is only when i change to 2 does it fail.
When it fails the program stops at an estop located at 0x3FE493...which is located in the c1brom_itrap_isr. This function is commented to say it is called when an illegal interrupt occurs. Interrupts are disabled when i call the API functions...
I did trace the failure once to the Fapi_setActiveFlashBank(Fapi_FlashBank0) call but the next time i ran the program it failed later in the program.
Any thoughts on cause? or how i can troubleshoot?
One other question - these API functions are running out of Flash memory. Is this ok? or should they be in RAM? If so, how do i tell the compiler to put them in RAM?
One more question - in the past (i forget which TI processor) the Flash API was in ROM. Is that feature not available on this processor?
I am using CCS 10.2.0.00009, compiler TI v20.2.5.LTS, C2000Ware_3_04_00_00, EABI (ELF) output type, and don't use driverlib.
Thanks!
Brett
