I am booting zephyr RTOS on OK1046A board that use nxp ls1046a SoC(cortex-a53),but it occur a memory fault each times after enable mmu on this platform.
I use openocd to debug it, and I guess that whether the core0's execution is affected by another core after mmu is enabled when boot zephyr on cpu0(Maybe cache's effect?). So I want to halted other cpus and just run cpu0. But i can not halt cpu2 and cpu3 using openocd with jtag.

And below is my openocd config file:

regards, thanks.
