\mainpage Introduction

This manual explains the scope and the usage of the Software Pack for <b>CMSIS-Driver Validation</b>.<br>
<a href="http://www.keil.com/pack/doc/CMSIS/Driver/html/index.html" target="_blank">CMSIS-Driver</a> specifies the 
software API for peripheral driver interfaces that connect microcontroller peripherals with middleware or the user application. 

The CMSIS-Driver Validation is used to validate the driver implementation compliance to the CMSIS-Driver specification.

The CMSIS-Driver Validation provides:
  - Configurable validation tests for various CMSIS-Driver interfaces
  - Example projects that show the usage of the CMSIS-Driver Validation
  - Various Servers used for testing

The CMSIS-Driver Validation tests and verifies:
  - <b>API interface</b> using the driver capabilities as well as valid and invalid parameters
  - <b>Data communication</b> with various transfer sizes and communication parameters:
    - <b>Loopback testing</b> (for some interfaces) for testing of the underlying hardware with usage of a local loopback
    - <b>Server testing</b> (for some interfaces) for extensive testing of the underlying hardware with usage of a dedicated Server
  - <b>Transfer speed</b> of the data communication with time measurement of data transfer duration
  - <b>Event</b> signaling

The CMSIS-Driver Validation requires
<a href="http://www.keil.com/pack/doc/CMSIS/RTOS2/html/index.html" target="_blank">CMSIS-RTOS2</a> functionality and can be
used to verify the setup and configuration of the CMSIS-Driver interfaces in a user system.<br>

The diagram below shows an overview of the CMSIS-Driver Validation configuration.

/**
\page setup Setup

\section step1 Step 1: Create an MDK project for your target microcontroller device


\section step2 Step 2: Add the required software components

For proper operation, add the following software components in the <b>Manage Run-Time Environment</b> window:
- <b>CMSIS Driver Validation: Framework</b>
- <b>CMSIS Driver Validation: driver</b>, driver interfaces to be tested
- <b>CMSIS Driver: driver</b>, driver implementations to be tested
- <b>CMSIS: RTOS2 (API): Keil RTX5</b>
- <b>Compiler: I/O: STDOUT</b>, variant \b ITM (if your hardware does not support ITM select \b EVR to use Event Recorder instead of ITM)
- Resolve any unresolved component dependencies


\section step3 Step 3: Add the application's main file (main.c)

Right-click <b>Source Group 1...</b> and select <b>Add New Item to Group</b>, select <b>User Code Template</b> and choose the
<b>CMSIS-RTOS2 'main' function</b> file from <b>CMSIS: RTOS2:Keil RTX5</b>.

Add this include:
\code
#include "cmsis_dv.h"
\endcode

In the <c>app_main</c> function, create the \c cmsis_dv thread, before endless <c>for</c> loop:
\code
osThreadNew(cmsis_dv, NULL, NULL);
\endcode
to run all the tests that you have chosen in the next step.


\section step4 Step 4: Configure the CMSIS-Driver Validation framework in DV_Config.h file

Open <b>DV_Config.h</b> under the <b>CMSIS Driver Validation</b> group in the Project window.

In the configuration file <b>DV_Config.h</b> select <b>Plain Text</b> as the <b>Report Format</b>.

\section step5 Step 5: Configure the interface settings and tests in related DV_interface_Config.h files

Each interface has a related <b>DV_<i>interface</i>_Config.h</b> file, where <i>interface</i> represents interface's acronym or abbreviation.<br>
For example for Serial Peripheral Interface (SPI) related config file name is DV_SPI_Config.h.

For details on interface specific configuration and test selection please check the Configuration section in the 
<a class="el" href="./modules.html">Reference</a> of the related interface.


\section step6 Step 6: Configure the Heap memory

Depending on the buffer sizes used for data transfer tests the heap size has to be adjusted to provide enough memory for these 
buffers to be allocated.<br>
Depending on how heap is configured in your system, open your <b>startup_<i>device</i>.s</b> file from the \b Device group in the \b Project window 
or use a <b>linker script</b> to adjust the heap size.<br>
Set the <b>heap size</b> to minimum of <b>16384</b> bytes.

For details on heap requirements please refer to the \ref heap_req "Heap Memory requirements" documentation.


\section step7 Step 7: Configure the CMSIS-RTOS2 (Keil RTX5)

Open <b>RTX_Config.h</b> and set:
- <b>System Configuration: Global Dynamic Memory size [bytes]</b> to \a 16384
- <b>Thread configuration: Default Thread stack size [bytes]</b> to \a 3072

For details on CMSIS-RTOS2 requirements please refer to the \ref rtos2_req "CMSIS-RTOS2 requirements" documentation.

\section step8 Step 8: Configure the Device

Depending on your device, you might have different pin/hardware configuration options. Usually, you can configure the device
using the \c RTE_Device.h file from the \b Device group or with a vendor provided pin configuration tool. 
Enable all interfaces you wish to test and make all necessary pin-out changes required by your actual board layout (consult the board schematics).<br> 
You can check the provided \ref examples "examples" as a reference point.

For a robust test with good coverage, implement various targets with different settings:
- Use <b>non-DMA (IRQ)</b> and <b>DMA</b> configurations if they are available on the driver
- Use different compiler <b>optimization levels</b> in the
  <a href="http://www.keil.com/support/man/docs/uv4/uv4_dg_adscc.htm" target="_blank">C/C++ tab</a> of the
  <b>Options for Target</b> dialog


\section step9 Step 9: Setup the required hardware

For the interfaces that support loopback testing: \ref dv_eth "Ethernet", \ref dv_usart "USART" and \ref dv_spi "SPI", 
connect the following pins on your target hardware together (refer to the hardware schematics):

- Ethernet: RX+ and TX+, RX- and TX-
- USART:    RX and TX
- SPI:      MOSI and MISO

For the interfaces that support testing with dedicated server: \ref dv_wifi "WiFi" and \ref dv_spi "SPI", 
connect the related hardware as required by the related server:

- WiFi: WiFi module has to be in close proximity to the Access Point which is in the same network as the required \ref wifi_sock_setup
- SPI:  MOSI, MISO, SCLK, SS, GND to the same lines on the \ref spi_server


\section step10 Step 10: Download and Run the Project

In the <b>Options for Target</b> dialog, under debug settings, if you use ITM as standard output channel ensure that 
\b Trace and <b>ITM port 0</b> are enabled and that the correct <b>Core Clock</b> frequency is set:

\image html target_dialog.png "ITM Channel setting"

Build, load and run the project. The output is displayed in the <b>Debug (printf) Viewer</b> window.<br>
Example below shows output result of an SPI driver testing:

\page report Report

The CMSIS-Driver Validation can output the test report in a <b>Plain Text</b> format or as an <b>XML</b> formatted file.<br>
Selection of the output report type is done in the <b>DV_Config.h</b> configuration file.

\image html dv_config_h.png "Configuration file DV_Config.h in Configuration Wizard view mode"

The <b>Plain Text</b> selection instructs the CMSIS-Driver Validation framework to generate a plain text report 
which can be seen in the <b>Debug (printf) Viewer</b> window and is mostly used for driver debugging purposes 
but can also be used as a final report.

The <b>XML</b> selection instructs the CMSIS-Driver Validation framework to generate an XML formatted report 
which is meant to be used as a final report and can be viewed nicely in any Web browser.<br>

The report file can be written into a <b>TestReport.xml</b> file directly by the uVision with an additional debugger script 
called <b>SaveXML.ini</b> which needs to be specified as <b>Initialization File:</b> for the <b>Debugger</b> in the 
<b>Options for target</b> dialog, or it can be copy-pasted manually from the <b>Debug (printf) Viewer</b> window to 
the TestReport.xml file.<br>
The SaveXML.ini script can be found in <c>\<pack root directory\></c><b>\\Scripts</b> directory.

To view <b>TestReport.xml</b> file in a Web browser an additional style sheet <b>TR_Style.xsl</b> file needs to be 
in the same directory as the TestReport.xml file.<br>
The TR_Style.xsl file contains the description of formatting for the Web browser to display the TestReport.xml report and 
can be found in <c>\<pack root directory\></c><b>\\Scripts</b> directory.


The XML file uses coloring to differentiate the results in the following way:
 - <span style="font-weight:bold; color:Green">Passed</span> status means that test function has passed successfully.
 - <span style="font-weight:bold; color:DarkOrange">Passed</span> status means that test function has passed but there were some warnings 
     (<c>More details</c> can be used to see the details about warnings).
 - <span style="font-weight:bold; color:Blue">Not executed</span> status means that test function did not check any assertions.
 - <span style="font-weight:bold; color:Red">Failed</span> status means that test function has failed 
     (<c>More details</c> can be used to see the details on reasons of failure).

Test Summary: 56 Tests, 24 Passed, 1 Failed.

\endverbatim

From previous report it is clear that one test function has failed.<br>
By Inspecting the details in previous report it is clear that <c>TEST 03: SPI_Initialize_Uninitialize</c> has failed 
on multiple assertions.<br>
Each failed assertion is recorded as a single  line in the test report.<br>
The failed assert information in the output report contains additional information about the <b>source module</b> and <b>line</b> 
in that module where the assertion is located with additional debugging info if available.

The documentation can be consulted regarding the failed function, for example in previous case 
documentation on the \ref SPI_Initialize_Uninitialize can be consulted.

Main way of fixing the driver consists of opening reported file mentioned as failed and inspecting the 
line in which failure was reported.

If there are many failures, it is recommended to deselect all tests except first failing one 
so it is easier to focus on just that failure.
Also, selecting only first failing test removes potential clutter from following failing tests that 
are all failing due to same cause.

In the previous report, opening <b>DV_SPI.c</b> module (available in the project) and inspecting the <b>1106</b> line 
which states:
\verbatim
  // Driver is uninitialized and peripheral is powered-off:
  // Call PowerControl(ARM_POWER_FULL) function and assert that it returned ARM_DRIVER_ERROR status
  TEST_ASSERT(drv->PowerControl (ARM_POWER_FULL) == ARM_DRIVER_ERROR);
\endverbatim

informs us that call to <c>PowerControl (ARM_POWER_FULL)</c>, when driver is not initialized, is expected to 
return <c>ARM_DRIVER_ERROR</c> status code but it has returned a different status code instead.

We should put a breakpoint to this line and start the debug session.<br>
When the breakpoint is hit we can see that a call to <c>PowerControl (ARM_POWER_FULL)</c> has returned <c>ARM_DRIVER_OK</c> 
instead of expected <c>ARM_DRIVER_ERROR</c> status code.

We can now go into source code of the driver and fix this.

After we have fixed the driver, the report now looks like below:

\verbatim
CMSIS-Driver SPI Test Report   May  6 2020   11:15:30 

TEST 01: SPI_GetVersion                   
  DV_SPI.c (1023): [INFO] Driver API version 2.3, Driver version 2.15
                                          PASSED
TEST 02: SPI_GetCapabilities              PASSED
TEST 03: SPI_Initialize_Uninitialize      PASSED
TEST 04: SPI_PowerControl                 
  DV_SPI.c (1314): [WARNING] PowerControl (ARM_POWER_LOW) is not supported
                                          PASSED
...

Test Summary: 56 Tests, 25 Passed, 0 Failed.
Test Result: PASSED
\endverbatim

The fix for the assertion failing in line 1106 has also fixed subsequent assertions 
in lines 1109 and 1112 thus the driver now reports no failed tests and reports that all 
of the 25 executed tests have passed.

This report could be used as an insurance that the SPI Driver on this device is compliant to the CMSIS-Driver specification.

The TestReport.xml report created instead of Plain Text opened in a Web browser looks similar to the the picture below:

\page resource_requirements Resource Requirements

\section heap_req Heap Memory
Heap memory is used by the memory allocation functions.<br>
It is usually configured in the <a class="el" href="http://www.keil.com/support/man/docs/gsac/gsac_startupcodecortex.htm" target="_blank">startup_device.s</a>
file located under the \b Device component class but it can also, in some cases,  be configured by a <b>linker script</b> instead.

Some interface test functions allocate additional buffers from the heap memory.

The CMSIS-Driver Validation framework does not impose heap requirements because it does not use heap memory.

Each interface test module has specific requirements for the heap memory, default requirements are listed below:

| Interface test module   | Heap memory requirement (in bytes) |
| :---------------------: | :--------------------------------: |
| CAN                     | 128                                |
| Ethernet                | 1024                               |
| SPI                     | 12288                              |
| USART                   | 8192                               |

Interface test modules that are not listed in the previous table do not use heap memory.

The system heap memory size must support the largest heap requirement of any used interface test module.<br>
For example, if SPI driver testing is selected heap memory size should be set to at least 12 kB.

Suggested value for heap memory size is <b>16384</b> bytes.

\note Each module contains additional settings in related configuration file which are not exposed through 
      Configuration Wizard and impact the heap memory requirement.<br>
      If these values are changed please adjust heap memory size accordingly.

\section rtos2_req CMSIS-RTOS2

The thread requirements need to be reflected in the CMSIS-RTOS2 configuration. Refer to the
<a class="el" href="http://www.keil.com/pack/doc/cmsis/RTOS2/html/index.html" target="_blank">CMSIS-RTOS2 Reference</a> for further details.

For <a class="el" href="http://www.keil.com/pack/doc/cmsis/RTOS2/html/rtx5_impl.html" target="_blank">CMSIS-RTOS2 RTX5</a>, thread
requirements are configured in the
<a class=el href="http://www.keil.com/pack/doc/cmsis/RTOS2/html/config_rtx5.html" target="_blank">RTX_Config.h</a> file located
under the \b CMSIS component class:

| Option                                                            | Value                              |
| :---------------------------------------------------------------- | :--------------------------------: |
| System Configuration: Global Dynamic Memory size [bytes] (Note 1) | 16384                              |
| Thread Configuration: Default Thread Stack size [bytes]           | 3072                               |

\note Note 1: This setting is only necessary for WiFi driver testing, for other driver testing value of 4096 bytes is sufficient.
