Refer device-specific data sheet for the R5F Tightly Coupled Memory (TCM) size information. Irrespective of the number of cores available, the TCM remains in the subsystem that can be used by the processor.
For AM642x, one core from each subsystem (cluster) is available resulting in 256K.
Note that lockstep is not supported on AM64x processors. Refer device-specific TRM.
