Hello Stellaris community,
I am working with a stellaris M4 launchpad ccs5.2.1. I am unable to determine why my code is tripping the imprecise data buss error sending me to faultISR. Using TI's app note "diagnosing software faults AN01286" it is similar to Bus Fault Scenario 2 with NVIC_FAULT_STAT register value of 0x400, imprecise data bus error. Looking through the disassembly I have found the last STR instruction as the app note recommends. It is a function which calls the HibernateDataSet stellaris function. However, I can't seem to see any issue with that. Hibernate has been enabled earlier in the code. I do realize this may be difficult with not being familiar with my code but I am desperate. Is there something else I should be looking at as to why this fault is being generated? I am still very new to stellaris and embedded programming so please bear with me.
Thanks,
Jeff
