tests/kernel: verify RUNTIME_NMI at runtime
This patch introduces a test that verifies the behavior of CONFIG_RUNTIME_NMI at runtime. The test is meant to be only for ARM Cortex-M targets. Change-Id: I805a88e67fe47d396ac9e29e1275e5452a4b8a36 Signed-off-by: Vincenzo Frascino <vincenzo.frascino@linaro.org>

Title: Test to verify the behavior of CONFIG_RUNTIME_NMI at runtime (ARM Only)
|
||||
|
||||
Description:
|
||||
|
||||
This test verifies the behavior of CONFIG_RUNTIME_NMI at runtime. Only for
|
||||
ARM Cortex-M targets.
|
||||
|
||||
---------------------------------------------------------------------------
|
||||
|
||||
Building and Running Project:
|
||||
|
||||
This project outputs to the console. It can be built and executed on QEMU as
|
||||
follows:
|
||||
|
||||
make qemu
|
||||
|
||||
---------------------------------------------------------------------------
|
||||
|
||||
Troubleshooting:
|
||||
|
||||
Problems caused by out-dated project information can be addressed by
|
||||
issuing one of the following commands then rebuilding the project:
|
||||
|
||||
make clean # discard results of previous builds
|
||||
# but keep existing configuration info
|
||||
or
|
||||
make pristine # discard results of previous builds
|
||||
# and restore pre-defined configuration info
|
||||
|
||||
---------------------------------------------------------------------------
|
||||
|
||||
Sample Output:
|
||||
|
||||
Trigger NMI in 10s: 0 s
|
||||
Trigger NMI in 10s: 1 s
|
||||
Trigger NMI in 10s: 2 s
|
||||
Trigger NMI in 10s: 3 s
|
||||
Trigger NMI in 10s: 4 s
|
||||
Trigger NMI in 10s: 5 s
|
||||
Trigger NMI in 10s: 6 s
|
||||

|
||||

|
||||

|
||||
