The CYGPKG_RTT package provides a standard Segger RTT (Real Time Transfer) implementation to eCos applications.

[Note]Note

Host access to RTT channels is not limited to the Segger debug tools. Access is supported by 3rd-party tools, including, for example, Ronetix PEEDI and OpenOCD. It is not a feature limited to use with J-Link/J-TracePro H/W debug setups.

This package is covered by an “AS IS” license as distributed in the original RTT package:
