Hi, NXP team

    According to the reference manual, the booting core after exit from STANDBY to DRUN is based on the configuration of MC_ME_CCTLn. If DRUN and RUNx are enabled in MC_ME_CCTL1, while DRUN is enabled in MC_ME_CCTL3 just before entering STANDBY mode, which core will be the booting core after wakeup?

     In the example above, if MC_ME_CADDR1 is BAF entry address, and MC_ME_CADDR3 is an application entry point, will both cores boot at the same time from the corresponding address specified by MC_ME_CADDRn, or boot failed according to the picture below.

    Looking forward for your reply.

    Best regards!
