Ownership Trace (OT)
Ownership Trace Process ID (PID)
offers development tools a mechanism to decipher which set of symbolics and sources are
associated for lower levels of visibility and debugging.
Ownership trace information is transmitted out the AUX using an Ownership Trace Message.
OTM facilitates ownership trace by providing visibility of which process ID or operating system
task is activated. An Ownership Trace Message is transmitted to indicate when a new pro-
cess/task is activated, allowing development tools to trace ownership flow. Additionally, an
Ownership Trace Message is also transmitted periodically during runtime at a minimum fre-
quency of every 256 Program Trace or Data Trace Messages.
In the AVR32, this feature is supported through an Ownership Trace Register, which automati-
cally produces an Ownership Trace Message when written to. The RTOS scheduler routine
writes the new process ID to this register during process switching using the mtdr instruction.
The TM[0] bit in the Development Control register must be set to enable ownership trace.
If there is no room in the Transmit Queue for the message, and the CPU is not halted to prevent
overruns, an error message is produced.
Table 9-52.
The CPU should write the current Process ID value to this register, whenever the RTOS per-
forms a process switch. This will automatically create an Ownership Trace Message to be
transmitted to the tool. This register can be written from any privileged CPU mode.
