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. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
