Introduction

This example shows the how custom data abort handler be implemented in the user application.

Provides information about the undef exception

1. address: Instruction causing the exception
2. spsr: Saved Program Status Register

Note

Please refer to R5F TRM for more information

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am263px-cc, am263px-lp
Example folder	examples/kernel/dpl/test_undef/

Steps to Run the Example

Note

This is a system or multi-core project, so refer to system project build instructions for CCS project or makefiles when building the example.

• When using CCS projects to build, import the system CCS project and build it using the CCS project menu (see Using SDK with CCS Projects). This will build all the dependant CPU projects as well
• When using makefiles to build, build the system makefile using make command (see Using SDK with Makefiles). This will build all the dependant CPU makefiles as well.
• This program cannot be loaded and run from CCS since it expects some sections of code/data to reside in flash
• To flash this program use the sample config file located at below.
• This config file has the filenames listed assuming application is built using makefile's and release profile. If you are using CCS projects or debug profile, edit this file to point to appropriate files.
• Now flash to EVM using the steps mention here, only use the config file mentioned above, Flash a Hello World example
• This is a multi-core example. Above steps will flash applications for all the CPUs.

Sample Output

Note

this application do not gives any output. This goes inside the HwiP_user_undefined_handler_c function and loops forever there. User needs to pause the applcaition and see the values.
