I am using ARM's DS-5+DSTREAM debug toolset to connect to my Hikey board and debug bare metal applications. While I can technically connect to all 8 cores, I can really only debug apps on core 0, because the status of all other cores is "powered down" when I connect to them. I contacted ARM support and they said to consult the board's manufacturer to determine how to power up the other cores.
I've tried looking through the Hikey documentation but I cannot find any mention of how to power up the other cores. Are there start-up options or boot conditions I can customize? I'm not sure how to proceed. Any insight is appreciated.
