When to set bit 13 for hardware breakpoint?
Bits 0 through 3 are set based on which hardware breakpoint is triggered. This is used to quickly check which breakpoint is triggered. Bit 13 is called BD and is set if the current exception is triggered because of access to a debug register.
How to set a hardware breakpoint in CCS?
The steps below describe how to configure a hardware breakpoint in CCS. Configure CCS for a C28x target and launch a debug session. In the Debug Perspective, open the breakpoint dialog from menu View → Breakpoints. Use the pull-down menu to select Hardware Breakpoint. In the Location field, specify the address where the breakpoint should be set.
How to set a hardware breakpoint on a C2000?
Use the pull-down menu to select **Hardware Breakpoint**.  4. In the Location field, specify the address where the breakpoint should be set. Alternately, if the code is programmed to Flash, double-clicking on a line of code in the editor will automatically set a hardware breakpoint.
Is there a way to set a data breakpoint?
“Data Breakpoints are not supported when using the legacy C# expression evaluator.” Data breakpoints are only supported on the non-legacy C# expression evaluator. Solution: You disable the legacy C# expression evaluator by going to Debug -> Options then under Debugging -> General uncheck “Use the legacy C# and VB expression evaluators”.
Are there any hardware breakpoints on the x64?
Hardware breakpoints are available on both x86 and x64. They are implemented with the help of 8 debug registers, named DR0 through DR7. These registers are 32- and 64 bits long on x86 and x64 respectively. The layout of the registers on an x64 architecture can seen on the figure below.
When do I get an exception for a breakpoint?
All breakpoint conditions on modern processors are exact. For compatibility with older hardware, it is recommend to always set both bits to 1. Bit 13 is called GD and is very interesting. If this bit is enabled, a debug exception will be generated whenever an instruction tries to access a debug register.
When to use a hardware breakpoint in debugging?
Hardware breakpoints are mainly used for debugging purposes. Unlike regular breakpoints, they do not require any code modification and are more versatile. Because of this, they are often used when debugging targets that utilise anti-debug tactics.
