Overview
========
This document highlights the steps to compile Linux device
driver test cases for A32.


Steps to compile using bitbake
==============================
1. Create Bolt Linux build project using the steps
mentioned in http://10.10.10.22:8081/doku.php?id=build_linux_kernel_rootfs_bolt_asic_rev_a0.

2. Once the project is created either using bolt-firmware-5.4 scripts
or build release tarball, run the following command to set the environment.
   $ source setup.sh

3. Build a32-linux-dd-testcases recipe using bitbake.
   $ bitbake a32-linux-dd-testcases

4. The compiled test cases can be found at
tmp/work/cortexa32-neon-poky-linux-musleabi/a32-linux-dd-testcases/1.0-r6/image/ directory.

   Note: By default the a32-linux-dd-testcases package will be part of alif-tiny-image rootfs,
and the pre-compiled binaries can be found under /opt/linux_dd_test/ directory.

Steps to compile using toolchain/SDK installer
==============================================
1. Fetch the SDK installer (.sh) file from the following link.
   Link: http://10.10.10.21/userContent/latest/Bolt_ASIC_Rev_A0_Linux_Application_Core/sdk/

   OR

   Build SDK installer using the bitbake using
   http://10.10.10.22:8081/doku.php?id=build_linux_kernel_rootfs_bolt_asic_rev_a0#f_build_toolchain_installer_using_bitbake

2. Install the SDK installer.

   Example:
   $ tmp/deploy/sdk/bolt-tiny-musl-x86_64-alif-tiny-image-cortexa32-neon-bolt-rev-a0-toolchain-0.1.sh
Alif Iota - Tiny Linux Distribution SDK installer version 0.1
=============================================================
Enter target directory for SDK (default: /opt/bolt-tiny/0.1): $PWD/bolt-tiny/0.1
You are about to install the SDK to "/var/lib/jenkins/Bolt-Rev_A0_daily/bolt-firmware-5.4/build/bolt-tiny/0.1". Proceed [Y/n]? y
Extracting SDK......................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
$ . /var/lib/jenkins/Bolt-Rev_A0_daily/bolt-firmware-5.4/build/bolt-tiny/0.1/environment-setup-cortexa32-neon-poky-linux-musleabi

3. Setup the environment variables.
   $ source  /var/lib/jenkins/Bolt-Rev_A0_daily/bolt-firmware-5.4/build/bolt-tiny/0.1/environment-setup-cortexa32-neon-poky-linux-musleabi

4. Change to a32_linux_DD_testcases directory and run 'make' to build binaries.
   The binaries are built under respective test case directories.
   $ cd a32_linux_DD_testcases
   $ make

5. To clean built binaries and object files run below command.
   $ make TARGET=clean

6. To install all binaries under 'image' directory run below command.
   $ make TARGET=install

Steps to add testcases
======================
The additional test cases can be added by following the below steps.

1. Create a new test name directory under testcases directory.
   Example:
   $ cd testcases
   $ mkdir -p i2c

2. Create a C testcase source file.

3. Create include directory and add optional needed ".h" files into it.

4. Copy the testcases/mhu/Makefile into the newly created test name directory.
   Example:
   $ cp testcases/mhu/Makefile testcases/i2c/

5. The top level Makefile compiles ".c" files under newly created test name
   directory.
