Setting up Lauterbach environment

The presented application example is for dual core microcontroller in Decoupled mode.

Demonstration is done for ST’s SPC56EL70 processor from chassis-safety family with

128kB RAM and 2MB Flash. Tools used are Lauterbach debugger and TRACE32

debugging interface. SPC56x families device combines DPM (decoupled) and LSM (lock-

step) modes. There are many ways how to debug Multicore processor. This section is about

Lauterbach debugger used for Multicore debugging, in our case dual-core debugging.

3.1

Dual-core debug environment

There is a possibility to debug dual-core processor with single TRACE32 PowerView

window, but for better orientation and easier debugging there is the possibility to start

multiple PowerView windows. The term Single Device Solution is used if one Lauterbach

device is used to debug all cores. Precondition is that the debug cable contains licenses for

all cores that should be debugged.

The following example describes how to start two TRACE32 instances. On a multicore chip

both cores are debugged via a joint JTAG interface by using a POWER DEBUG

INTERFACE / USB 2.
