Running and Debugging the Application Using XSDB - 2025.1 English - UG1209

Before you run the application, set a breakpoint at main():

xsdb% bpadd -addr &main

This command returns the breakpoint ID. You can verify the breakpoints planted using the command bplist. For more details on breakpoints in XSCT, type help breakpoint in the XSCT console.

Resume the processor core:

xsdb% con

The following informative messages will be displayed when the core hits the breakpoint.

xsdb% Info: Cortex-R5 #0 (target 7) Stopped at 0x100050 (Breakpoint)main() at testapp_r5.c: 86
86: {

At this point, you can view registers when the core is stopped:

xsdb% rrd

View local variables:

xsdb% locals

Step over a line of the source code and view the stack trace:

xsdb% nxt
Info: Cortex-R5 #0 (target 7) Stopped at 0x10005c (Step)89:     Status = PsUartSetup(&InterruptController, &UartPs,
xsdb% bt

You can use the help command to find other options:

You can use the help running command to get a list of possible options for running or debugging an application using XSDB.

You can now run the code:

xsdb% con

At this point, you can see the Cortex-R5F application print a message on the UART-1 terminal.
