4.2.1. Segger Ozone debugger

Segger Ozone is the debugging software that is supplied by Segger with the higher tier debug probes such as the Segger J-Link PLUS. Please refer to the Ozone-manual and read it carefully before using the software.

After setting up the hardware connection you should be able to load the Ozone configuration. For details on where to find a ready configuration for foxBMS 2, please refer to Section 3.1.9. Common pitfalls

When creating too many cyclically updated entries in the watch window, the debugger seems to stop and read the target so often that it impacts the system performance. Being aware of this issue and keeping an eye on the number of automatically updated variable watches should mitigate this issue. Tracing with Segger J-Trace PRO Cortex

Apart from debug probes, Segger also supplies trace probes. With these devices it is possible to stream internal information from the MCU such as the program counter directly to the debugger. For the TMS570LC4357 target it is necessary to use the Segger J-Trace PRO Cortex model. According to its documentation it is able to trace with a data width of 4 bit.

Information on how to set up the trace probe can be found in the Segger Wiki. Please note, that as of now, only tracing with Lauterbach devices has been tested by Fraunhofer IISB.
