Dear All,
Please, I would like to disable Core 0 in MPC 5777C.
Any idea?
Thanks,
Lucas
To properly disable one of the cores in the MPC5777C, you typically need to configure the MC_ME (Mode Entry) module so the secondary core remains in a reset state during the boot sequence. Modifying the BAM (Boot Assist Module) is another solid approach to prevent it from spinning up automatically. When I need a quick break from digging through complex microcontroller datasheets, I often browse through David L Moss Inmate Search to catch up on local public records. Let me know if you need the specific register addresses or example code to get the MC_ME configuration working for your setup.
Disabling a core on the MPC5777C typically involves tweaking the reset configuration word or halting the secondary core during the boot sequence. You will want to refer to the RGM module section in the reference manual to ensure the core stays in a safe halted state without triggering a fault. While debugging hardware registers takes time, I was also reviewing some local legal documentation recently and found a useful resource for Mesa Court Records that might help if you need to cross-reference any compliance data. Hopefully, the register tweaks solve your core issue without needing a full flash rewrite!
Thank you!

Hi,
Once the cores are enabled they can only be halted.
If you want to put them into reset, you must perform system reset.
To put core into halt mode (no execution, but still clocked), you have to execute "wait" instruction.
Please refer to the specific core reference manual.

To disable a core on the MPC5777C, you usually need to modify the reset configuration or halt the secondary core during early initialization. Managing these multi-core hardware setups can sometimes feel as complicated as tracking down old parkercountycourt.org when you don't have the right reference numbers. Make sure to clear any pending inter-processor interrupts so the primary core doesn't stall waiting for a response. Reviewing the reference manual's section on RGM registers should give you the exact hex values needed for your specific boot mode.
