MMDSP Debugger 5
©1989-2019 Lauterbach GmbH
Quick Start
1. Start the ARM debugger (for details see “Quick Start of the JTAG Debugger” in “ARM
Debugger” (debugger_arm.pdf)) of the Nomadik, and set local memory bus frequency to
10 MHz:
2. Only required for Tracing via NEXUS: Enable NEXUS via ARM debugger
3. Start the MMDSP debugger, select the device prompt B:, if the device prompt is not active after
the TRACE32-Software is started.
4. Select the core on your target, if automatic detection is not possible:
5. Configure the Debugger to use on-chip breakpoints in memory areas that are read-only (e.g.
FLASH/ROM):
If a program breakpoint is set within the specified address range, on-chip breakpoints are now used
instead of software breakpoints. A list of all available on-chip breakpoints for your architecture can be
found under On-chip Breakpoints.
6. Enter the debug mode.
This command resets the CPU and enters the debug mode. After SYStem.Up it is possible to access
the registers and the memory.
