Fig. 3.6 shows the most relevant buttons in Trace32. For a normal download onto the target with a subsequent debug session you have to select the ELF file, then set the target to “Up”-state, download the ELF file onto the target and then press the “Up and Go”-button in order to reset the target and start with an attached debugger.

3.2.3.6. Using a trace probe

If debugging alone is not sufficient and additional trace capabilities are required, Lauterbach supplies in addition to the debug probes also a trace probe for the TMS570LC4357 target. Please refer to their customer support for details.

The trace setup of Fraunhofer IISB consists of a LA-3505 debugger connected to a LA-3580 trace probe with the LA-7992 parallel preprocessor for ARM/Cortex architectures. foxBMS 2 features a compliant Mictor-38 connector in order to be able to connect trace ports with up to 8 bit. If you need more bandwidth, please contact us. The standard design can be adapted to up to 32 bit trace bandwidth.
