The host is an x86 machine with Linux OS. The single UART needs to provide connectivity to all the processors on the target and the debug tool needs to do processor specific commands (breakpoints, source-level debug, etc.). Can you guys please point me to any reference material, implementations, etc. for me to get started with this? Thanks much for your help. Regards, -Srinivas
