Title: Semaphore APIs
|
|
|
|
Description:
|
|
|
|
This test verifies that the nanokernel semaphore APIs operate as expected.
|
|
|
|
---------------------------------------------------------------------------
|
|
|
|
Building and Running Project:
|
|
|
|
This nanokernel 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
|
|
|
|
