Intel does provide a hardware debuggger, such as ITP-XDP (https://designintools.intel.com/In_Target_Probe_Debug_Tool_Kit_p/itpxdp3brext.htm).
And mainboard of SuperMicro have a debugging connector for the debugger(XDP on x86 Core motherboard? |Embedded Community).
Unfortunately, I cannot buy the debugger since Intel sells the debugger to those who have NDA.
Does AMD have such a debugger and mainboard?
Also, can I buy them?
