Respectively, it now only works when all four ports (DEBUG_TEXT_PORT, STDIO, DEBUGGER_PORT and MESSAGING_PORT) are set to the same value and it has to be either USBx or COMx.\r\n\r\nIn Tinybooter (Initialization\\tinyhal.cpp) the communication initialization function CPU_InitializeCommunication() is never called (conditional compilation), so the initialization of STDIO depends on its type - if it is set to ITM0, it never happens, if it is set to USBx or COMx, it is initialized when either debugger or messaging does it, whichever is called first."}}
