SK-AM64: Does the chip support both Different operating systems running on the A53 core（AMP ）?

Part Number: SK-AM64

Whether running different operating systems on two A53 cores is limited at the chip hardware level？We want to develop our own operating system to run in AMP mode on A53，So we would like to confirm whether there are any restrictions at the chip hardware level.

The dual Cortex A53 on AM64x (And all AM6x) is a standard implementation which includes the ability to run more than one operating system using the hypervisor privilege level and two stage MMU. See Cortex A53 technical reference manual https://developer.arm.com/documentation/ddi0500/latest/ and the Arm v8 architecture reference manual https://developer.arm.com/documentation/ddi0487/latest/ for details.

If your goal is Linux and an RTOS, my first suggestion is use A53 for Linux and R5 for RTOS, this is what the TI SDKs support out of the box. Next level of complexity would be Jailhouse to run Linux and RTOS on A53.
