I found follow information in ecos-tutorial-ppc . I want to know how can I get this information for trace and test.use codetest? thanks information: 80 Getting Started with eCos eCos Appendix 1: Real-time characterization For a discussion of real-time performance measurement for eCos, see the eCos Users’ Guide.
