 Challenge:

“MCUs continue to become more complex especially when creating applications to enable the Smart Society, and

therefore the tools become more complex as well As a result we must create tools that enable complete debug capability at minimal cost.”

 Solution:

“OpenSource IDE’s with custom layers must be developed to enable engineers to create applications for the 2010’s”

Agenda

E 2 STUDIO ADVANCED DEBUGGING

e2Studio Advanced Debug Views

 Advanced capabilities for hardware debug launches only

 I/O register presentation and manipulation

 Real-time state presentation

 Configuration of eventpoints

 Tracing of low-level address and data accesses

GDB Server

GDB

GDB port

ADM port

USB

IO Registers View

 Presentation of memory-mapped IO ports

 Register sets defined in target-specific IO files

 Register selection

configurations

 Read and write capabilities

 Changes highlighted

 In-cell editing

 Refresh on demand

 Refresh lock

 Default register sets

Realtime Expressions View

 Monitor the value of user-defined expressions while target is running

 Access to global variables only

 Enable and disable real-time data capture

 Realtime Memory view allows inspection of raw memory

 Realtime Chart view plots a pair of variables against time

Eventpoints View

 Eventpoints describe the triggers for some sort of activity

 Before PC eventpoints

 Special class of eventpoint behaving as a breakpoint

 Manipulate via Before PC Eventpoint context menu items

in editor margin

 Event Break eventpoints

 Special class of eventpoint that can be used as a

watchpoint

 Manipulate via Eventpoints view specifying type Data

Access

 Eventpoints applied to target when resuming

 Optionally edit and apply eventpoints while target running

 Associate a trigger count to ignore initial trigger matches

 Trigger every Nth time a line of code is executed

 Trigger every Nth time a variable is read

 Eventpoints persistent at the project level

Eventpoints For Tracing

 More generally, eventpoints used to trigger tracing

 Trace start

 Trace stop

 Trace record

 Trace records presented in Trace view

 Trace starts automatically where no trace start eventpoint defined

 Trigger on execution address or data access with optional condition

 Combine eventpoints with OR, AND and SEQUENCE logic to create complex triggers

 Limited number of eventpoints available (hardware

dependent)

 Force Hardware Breakpoints launch option must be disabled

Trace View

 Trace data captured to buffer in real-time

 Trace acquisition depending on hardware capabilities

 Presentation modes

 Filtering options operate at user interface level
