PROCESSOR-SDK-J721S2: SDL_POK Instances configurations

Tool/software:

Hello, 

I am configuring multiple POK instances and need clarification for the following instances:

  1. SDL_POK_VDD_MCU_OV_ID                         (10)
    1. The code checks for a NULL pointer address in 
      SDL_pokSetOperation function as seen in the attached image.
  2. SDL_POK_VDDSHV_WKUP_GEN_ID                    (8)
    a. What is the voltage rail connected to it?
    3. I cannot find POK Instance VDD_CPU1 in the current sdl_ip_pok.h, so is it in another version or sdl or what?

    You can add a check for NULL value before performing PP DISABLE as shown below. An internal bug has been raised against this issue as well and will be updated in the future releases.

    This is used to monitor the VDDSHV0_MCU voltage.

    I see the SDL_POK_VDD_CPU1_ID defined in the latest SDK 10.1 release.
