---|
11 | |
---|
12 | RTEMS Tracing Framework is an on-target software based system which helps track |
---|
13 | the ongoings inside the operation of applications, 3rd party packages, and the |
---|
14 | kernel in real time. |
---|
15 | |
---|
16 | Software based tracing is a complex process which requires components on both |
---|
17 | the target and the host to work together. However its portability across all |
---|
18 | architectures and board support packages makes it a useful asset. A key |
---|
19 | requirement in RTEMS trace process is to take existing code in compiled format |
---|
20 | (ELF) and instrument it in order to log various events and records in real time. |
---|
21 | However instrumenting of the code for tracing should happen without rebuilding |
---|
22 | the code from the source and without annotating the source with trace code. |
