AM3517: WinEC 7 CPU_INFO area

Other Parts Discussed in Thread: AM3517

Hi,

I'm working with the Adeneo WinEC 7 BSP for AM3517 and I'm wondering about the CPU_INFO area. What is this? And who initializes this area?

Best regards,

Andreas

    The CPU_INFO is a data strcuture stored in RAM that is used by the OALCPUIdle ASM function (cpu.s) that is called from internal SRAM to put the CPU to idle. This structure contains all the register addresses and information that this function requires to do its job.

    This data zone is entirely managed by the power management mechanism of the BSP and should not be modified. The only thing that you should take care of when customizing the BSP is to reserve some space in RAM for this structure in the memory mapping of your image (throufh the image_cfg.h file).
