Trace32 in-circuit emulators, debuggers, and simulators for the PowerPC family now include ready-to-run support for the eCos operating system. The eCos source code is distributed under the GNU general public license. Existing Trace32 customers receive eCos compatibility for free. At present, eCos compatibility is available only for those Trace32 tools that support the PowerPC processor, but additional processor ports are planned. By means of these tools, the OS's scheduler and threads can be viewed in special windows. A stack analysis capability measures the stack usage of each thread. Based on the sampled records in Trace32 analyzers, thread switches can be graphically examined and displayed. A performance analysis tool evaluates thread and function run times. Statistic tables give information about system usage. The Trace32 debugger supports the eCos RTOS without requiring changes to the application or kernel.
