Omap3530 IDLE ENTRY

Other Parts Discussed in Thread: SYSCONFIG

Hi Everyone,

        The article OMAP35x Debug Steps for Idle Entry seems not completely work for me.

        The thing is I follow every step ,like IRQ Pending, only DPLL3 in locked, etc.

         Mine is Omap3530. Till now I' m still stuck in the CORE Domain IDLE Transition. After I finish WFI, 

the function return immediately. It turns out that MPU Domain got into retetion, but CORE Domain never did.

         I' m wondering if there is anything i miss. Could you give me some advice?

         Thanks in advanced

Best regards

    Hi Zhaoshuai,

    If you have a JTAG access, can you dump registers in attached text file before WFI ? Please make sure MMU is turned off when you dump them. The sysconfig registers need to be dumped last as they require iclk and fclk to be enabled. 

    Here are registers and settings for turning on requried iclk and fclk. Please run them before you dump sysconfig registers.

    CM_ICLKEN1_CORE = 0xFFFFFFFF;
    CM_ICLKEN3_CORE = 0x00000004;
    CM_FCLKEN1_CORE = 0xFFFFFFFF;
    CM_FCLKEN3_CORE = 0x00000006;
    CM_ICLKEN_PER = 0x0003FFFF;
    CM_FCLKEN_PER = 0x0003FFFF;
    CM_CLKSTCTRL_PER = 0x00000002;
    CM_ICLKEN_WKUP = 0x000000FF;
    CM_FCLKEN_WKUP = 0x000000FF;
    CM_FCLKEN_DSS    = 0x00000001;
    CM_ICLKEN_DSS    = 0x00000001;
    CM_CLKSTCTRL_DSS = 0x00000002;

    Some of the registers were failed to be dumped for I didn't work at it in CCS. Dose it matter ?  As I know, They belong to IVA Domain, USBHOST Domain OR CAM Domain, all of which have gone into Idle.

    Is there anything wrong?

    Hi Zhaoshuai,

    OTG_SYSCONFIG.SIDLEMODE is set to no-idle and OTG_SYSCONFIG.MIDLEMODE is set to no-standby. Can you change OTG_SYSCONFIG.SIDLEMODE to Force-idle and OTG_SYSCONFIG.MIDLEMODE to Smart-Standby ?

    OTG_SYSCONFIG      : 0x480AB404        0x00001008 -> 0x00002001

    Can you also change below register setting ?

    CM_CLKSTCTRL_CORE    : 0x48004A48        0x0000000f -> 0x0000003f

    The registers that weren't accessible are not required, please use attached updated list next time.

    Hi Kazunobu,

    Did you manage to get to idle ?

    Thanks
