Debugging SCP Firmware

Download the RD software stack

Build the software stack

Set up the model for debugging

Run the model

Connect the model to Arm DS

Create a new debug configuration

Open Arm DS

In the Debug Control window, click on the menu icon and select "New Debug Connection..." 

Select "Model Connection" and click next

Create a name for the connection. We will call it "RDN2 SCP" and click next

Select "Add a new model"

In the new window which appears, select CADI and click next

Select "Browse for model running on localhost" and click next

Select "System Generator:RD_N2" This will only appear while the FVP_RD_N2 window is open when running the model

Click Finish on both windows

In the edit configuration window which appears we need to select which core to debug.

Under Connection -> Select Target -> Imported -> RD_N2 -> Bare Metal Debug we can see all the cores available in our model

We are only interested in the Cortex M7 cores, which are the MCP and SCP.

Select Arm_Cortex-M7_1

Under Files select Load Symbols from file, File System, and select the SCP RAMFW ELF file, located at `scp/output/rdn2/0//scp_ramfw/bin/rdn2-bl2`

Select apply then debug
