[lldb-dev] did anyone konw LLDB support lldb + openocd to run dotest.py in bare board like ARM or other non-x86 architecture?

Yes lldb-server does support a full connection to a remote OS. On baseboards you are typically debugging the entire OS so lldb-server won't work because you have to OS to run it in the background. Supporting the test suite on baseboards will take some effort.

This requires a running lldb-server on the remote system, so we only have the test suite running when we have the lldb-server running in platform mode on the other side. For this to work with baseboards, we would need the JTAG box to respond to many GDB remote protocol packets that "lldb-server platform" implements. I am sure for baseboards the test suite would need to be modified. A few ideas there:
