    Hello Shi Guillin,

    You can use the warm reset option that will reset all the cores.
    You can invoke the same by entering the below mentioned code

    //warm reset test
                   
    #include <kernel/dpl/ClockP.h>
    #include <drivers/hw_include/cslr_soc.h>
    #include <drivers/soc.h>
    #define KICK_LOCK_VAL                           (0x00000000U)
    #define KICK0_UNLOCK_VAL                        (0x01234567U)
    #define KICK1_UNLOCK_VAL                        (0x0FEDCBA8U)
    #define IOMUX_KICK0_UNLOCK_VAL                  (0x83E70B13U)
    #define IOMUX_KICK1_UNLOCK_VAL                  (0x95A4F1E0U)
                   
                    uint32_t            baseAddr;
                    volatile uint32_t  *kickAddr;
                    uint32_t             i=0;
                    uint32_t            value=0;
                    baseAddr = CSL_MSS_TOPRCM_U_BASE;
                    kickAddr = (volatile uint32_t *) (baseAddr + CSL_MSS_TOPRCM_LOCK0_KICK0);
                    CSL_REG32_WR(kickAddr, KICK0_UNLOCK_VAL);   /* KICK 0 */
                    kickAddr = (volatile uint32_t *) (baseAddr + CSL_MSS_TOPRCM_LOCK0_KICK1);
                    CSL_REG32_WR(kickAddr, KICK1_UNLOCK_VAL);   /* KICK 1 */
                    uint32_t* regAddr = (uint32_t*)0x02140100;
                    uint32_t dbg = *regAddr & 0xFFFFF8FF;
                    while(i<0xFFFF){
                        i++;
                    }
                    *regAddr = dbg;
     //warm reset end

    You can make this into a function and then invoke the same where required.

    Hello Saswat ,

    I executed this code，The effect is the same as Bootloader_socCpuResetReleaseSelf().

    The program stopped，but bootloader can‘t restart.

    Can i realize Power On Reset with software?(Features on the following pictures)

    Regards,

    Hello Shi guillin,

    Please try the same code with the MMWAVE SDK 4.3.1 which is the new SDK version.
    The warm reset Code that I have provided is the only way to achieve all the cores restarting.
    The above code has been tested and it works, but there was a warm reset issue in the SDK 4.2.3 which is fixed in the latest SDK release 4.3.1.

    Regards,
    Saswat

    Hello Saswat ,

    Because my current project is based on SDK 4.2.3，I have achieved restart in other ways.

    I will try it when my project SDK is updated.

    Thank you for your support！！！

    Regards,
