Compiler/PROCESSOR-SDK-AM437X: CPU actual frequency

user5371084

Part Number: PROCESSOR-SDK-AM437X
Other Parts Discussed in Thread: AM4376

Tool/software: TI C/C++ Compiler

the function BIOS_getCpuFreq() seem to return the value of BIOS.cpuFreq.lo in .cfg file, which is not the actual running frequency of AM4376 cpu.

How to get it? any API function?

Hi Zhuangbin,

The status can be checked by below GEL function:

ccs910/ccs/ccs_base/emulation/boards/evmam437x/gel/AM437x_Status.gel --> MPU_PLL_settings()

I can not find similar MPU_DPLL status function in RTOS/PDK package. You can implement your own, based on GEL file MPU_PLL_settings() function.

Regards,
Pavel
