Other Parts Discussed in Thread: C2000WARE
Hello,
I stumbled upon the following code in flash.h (driverlib/2838x/driverlib_cm).
#ifdef __cplusplus
#pragma CODE_SECTION(".TI.ramfunc");
#endif
static inline void
Flash_setWaitstates(uint32_t ctrlBase, uint16_t waitstates)
{
//
// Check the arguments.
//
ASSERT(Flash_isCtrlBaseValid(ctrlBase));
//
// waitstates is 4 bits wide.
//
ASSERT(waitstates <= 0xFU);
//
// Write flash read wait-state amount to appropriate register.
//
}
It seems to me the actual write to the register is missing here.. When I check version 4.01.000 of c2000 ware. The register is actually written. With the following:
HWREG(ctrlBase + FLASH_O_FRDCNTL) =
(HWREG(ctrlBase + FLASH_O_FRDCNTL) &
~(uint32_t)FLASH_FRDCNTL_RWAIT_M) |
((uint32_t)waitstates << FLASH_FRDCNTL_RWAIT_S);
