How to Sync Debug
In this topic:
•Master winIDEA Workspace Configuration
•Slave winIDEA Workspace Configuration
Introduction
For synchronous debugging of two Infineon AURIX devices, two winIDEA Workspaces have to be created, a Master Workspace and a Slave Workspace. Add-on modules are optional and not an essential part of the sync setup. Both iC7max/iC5700 Hubs are connected via the FBridge cable which enables synchronous debug.
|
The Sync Debug functionality is supported for Infineon TriCore architectures. |
For a general overview, refer to Multi-SoC Synchronization.
Example setup with two iC7max BlueBox
Requirements
•2x iC7max/iC5700 BlueBox Debuggers with Hub
•Infineon DAP/DAPE II
•Infineon AGBT Active Probes
•2x Infineon AURIX targets
•1x FBridge Cable
•2x CAN/LIN Add-on modules (optional)
•CAN Cable(s)
Hardware Configuration
|
Setup and Configure Hardware for both BlueBox Debuggers. |
|
Connect BlueBox Debuggers via the FBridge synchronization port. |
|
Open the winIDEA Workspace intended to be the winIDEA Master Workspace. |
Master winIDEA Workspace Configuration
You can freely choose which of the two AURIX devices will act as the Master and which as the Slave.
|
Configure the connection with the Active Probe. |
The DAP clock frequency should be set to a high clock rate for an optimized target status polling rate. A high target polling rate improves the sync debug latencies as well as the time synchronization between on-chip timestamp and the BlueBox timestamp. The maximum possible clock rate mainly depends on the DAP signal routing on the target board.
|
Configure the FNet Network description for Active Probe and CAN/LIN. |
|
Synchronize the Master in Hardware | Options | BlueBox Sync. |
•Select This winIDEA instance is synchronization master from the Synchronization drop-down menu.
•Enable Synchronize time.
•Define the path to the Slave workspace via Add.
|
Perform Debug | Download or Debug | Load Symbols Only. |
The Slave Workspace will open automatically.
After successful download and launch, the Debug Status is shown:
•Master Workspace STOP*
•Slave Workspace ONLINE (ready to ATTACH)
|
Configure the FNet Operation for the Active Probe in Hardware | FNet Operation | Active Probe. |
•Enable Recording is enabled from the start via the Qualifier button.
•Check all the options to establish synchronization:
oStop on StopSync
oRun on RunSync
oUse fast status checking
oGenerate StopSync when stopped
Slave winIDEA Workspace Configuration
|
Configure the connection with the Active Probe. |
|
Configure the FNet Network description for Active Probe and CAN/LIN. |
|
Synchronize the Slave in Hardware | Options | BlueBox Sync. |
•Select Allow slave-sync operation in the drop-down menu.
•Enable Synchronize time.
|
Perform Debug | Download or Debug | Load Symbols Only. |
After successful download and launch, the Slave Workspace Debug Status shows be STOP* (same as Master Workspace).
|
Configure the FNet Operation for the Active Probe in Hardware | FNet Operation | Active Probe. |
•Enable Recording is enabled from the start via the Qualifier button.
•Check all the options:
oStop on StopSync
oRun on RunSync
oUse fast status checking
oGenerate StopSync when stopped
Synchronized Debug Operation
This section describes the basic synchronized debug operations and its Debug Statuses. The * indicates that synchronized debug is currently active.
Action |
Debug Status |
|
|---|---|---|
Master |
Slave |
|
Download |
[CPU0] STOP* |
STOP* |
Run Master |
[CPU0] RUN* |
RUN* |
Run Slave |
[CPU0] RUN* |
RUN* |
Breakpoint hit in Master |
[CPU0] STOP* |
SUSPENDED* |
Breakpoint hit in Slave |
[CPU0] SUSPENDED* |
STOP* |
Single-Step Operations
Single-Step operations on the Master do not have any effect on the Slave. The Slave remains in SUSPENDED* . While in SUSPENDED* , single-step operations (source-level or assembly-level) are not possible. Single-Step is only possible when the SoC is in STOP* .
For more information about the statuses, refer to Debug Status.
