Connecting debugger to non active ARM core on 66ak2h12

Other Parts Discussed in Thread: 66AK2H12

Hello Support Team,

After configuring Linux for 66ak2h12 to only use 2 ARM cores, I would like to connect the debugger to any of the other two cores. I get the following response:

Error connecting to the target:
(Error -6503) PRSC module failed to write to a router register.
(Emulation package 5.1.507.0)

We can connect to the DPS:s and debug them, so the debugger is at least connected in the correct way.

I would like to connect to the ARM, download some code to RAM and execute it. Is this possible to do via the debugger? If so, any idea what I'm doing wrong?

Thank You,

/Peter Lööf

    Yes, it is possible to connect the debugger to the other cores.  You have to use the mon_power and power the core 1 up and then connect the other cores.

    Hi Peter,


    Try the following commands in u-boot prompt to connect the ARM core 3.

    To power up core 3:

    tftpboot 0x0c5f0000 skern-keystone-evm.bin

    mon_install 0x0c5f0000

    mon_power 3 1

    Now try to connect core 3 now in CCS.

     

    Regards,

    Shankari.

    I tried what you suggested to wake up the third core. It didnt work. The uboot termial simply hangs after I type mon_power 3 1.
