Other Parts Discussed in Thread: HALCOGEN, CODECOMPOSER
Hi. We are using the Hercules RM48L942 with HalCoGen generated function capGetSignal(hetRAMBASE_t * hetRAM, uint32 cap, hetSIGNAL_t signal). We are using the Micrium OSII on top of the HalCoGen drivers. When we call the capGetSignal function, writing to the signal->duty and signal->period triggers an ARM exception. Is there some type of lock on accessing this signal? Even just simple test of trying to create a hetSIGNAL_t structure and writing to the period and duty fields triggers the exception. Is there a HalCoGen function we need to call before being able to use the capGetSignal function? Thank you.
