Is it possible to remote debug a multicore system of which each core has different instruction set arch? For example if I have a two core chip, one core is cortex-m3, the other is riscv-i32. Or if I can debug multiple chip at the same time, each of which is different arch? I think this feature is important, since in the future there will be more debug situations like this.

If such a heterogeneous hardware system exists, the different cores will necessarily be running different
OS images. So treat it as debugging two physically separate machines, nothing different from today.

fwiw, this situation isn't theoretical. TI makes an ARM + C6X SoC
combo where both run Linux.
