![]() ![]() In the following I describe how to use RTT in an application. The difference between RTT and normal semihosting is that RTT is handled at the probe level, and not at the debugger level. Maybe Segger will add generic file I/O in RTT in the future? This is not enough to dump gcov trace and coverage data, as this would need multiple files. There is a dedicated RTT channel for reading/writing to a file, but this is for a single file only. Unless I would add a special RTT client on the host. So I can send/receive data over communication channels with RTT, but there is no logic implemented to open/store files. □ Currently RTT does not support file I/O what is now supported by the Segger Semihosting implementation. Have a look at to understand how RTT works. This can be used for sending/receiving text and data. Similar to semihosting, RTT provides a bidirectional channel between the target and the host. ![]()
