Data Fields | |
| uint32_t | cpuFreqKHz | 
| uint32_t | extClkKHz | 
| Osal_HwAccessType | hwAccessType | 
| uintptr_t | osalDelayTimerBaseAddr | 
| Osal_memRange | extSemaphorePBlock | 
| Osal_memRange | extHwiPBlock | 
| uint32_t Osal_HwAttrs::cpuFreqKHz | 
CPU frequency in KHz
| uint32_t Osal_HwAttrs::extClkKHz | 
External Clock value in KHz
| Osal_HwAccessType Osal_HwAttrs::hwAccessType | 
Hardware access type
| uintptr_t Osal_HwAttrs::osalDelayTimerBaseAddr | 
Delay timer base address: Delay timer base configuration is applicable for only AM335x/AM437x SoCs It is not applicable and should not be set for other SoCs Osal setHwAttrs API would return failure (osal_UNSUPPORTED) if attempted to be set for SoCs other than AM335x and AM437x.
| Osal_memRange Osal_HwAttrs::extSemaphorePBlock | 
Semaphore external memory control block
| Osal_memRange Osal_HwAttrs::extHwiPBlock | 
Hwi external memory control block
