Chapter 4  Forethoughts

4.1.
General

Following information will aid the user to use the DIO Driver Component
software efficiently.

•  The DIO Driver does not enable or disable the ECU or Microcontroller
power supply. The upper layer should handle this operation.

•  Start-up code is not implemented by the DIO Driver.

•  DIO Driver does not implement any callback notification functions.

•  DIO Driver does not implement any scheduled functions.

•  DIO Driver supports the Readback feature.

•  The DIO Driver Component is Postbuild time configurable for R4.0.3.

•  The file Interrupt_VectorTable.c provided is just a Demo and not all
interrupts will be mapped in this file. So the user has to update the
Interrupt_VectorTable.c as per his configuration.

•  To access the Hardware Registers, The MCAL user should use the Low
Level driver Layer. The MCAL user does not write or read any data directly
from any register, but uses the AUTOSAR standard APIs provided by the
MCAL Layer.

•  When the channel is configured as Output, then the PPR register will
reflect the Hardware pin level only when the Port Bi-Direction Control
Register(PBDC) is enabled. Or else only the Port register value will be
updated in the PPR register for the Output configured channels.

•  DIO Driver at initialisation, does not initialise or write on any registers.

•
Integrator should ensure that usage of DIO and PORT from two different
OS tasks are avoided and PORT configured as high priority task.
4.2.
Preconditions

Following preconditions have to be adhered by the user, for proper
functioning of the DIO Driver Component:

•  The Dio_Cfg.h and Dio_PBcfg.c files generated by the DIO Driver
Component Code Generation Tool have to be linked along with DIO
Driver Component source files.

•  File Dio_PBcfg.c generated by DIO Driver Component
Generation Tool can be compiled and linked independently.

•  The application has to be rebuilt, if there is any change in the Dio_Cfg.h
and Dio_PBcfg.c file generated by the DIO Driver Component Generation
Tool.

•  Dio_Ram.c and Dio_Ram.h are used only for Autosar release 4.0.3.

•  The DIO Driver Component needs to be initialized before accepting any API
requests. Dio_Init should be called to initialize DIO Driver Component.

19

Chapter 4                                                                                                                                            Forethoughts

•  The authorization of the user for calling the software triggering of a
hardware reset is not checked in the DIO Driver. This will be the
responsibility of the upper layer.

•  The user should ensure that DIO Driver Component API requests
are invoked with correct input arguments.

•  Input parameters are validated only when the static configuration
parameter DioDevErrorDetect is enabled. Application should ensure that
the right parameters are passed while invoking the APIs when
DioDevErrorDetect is disabled.

•  A mismatch in the version numbers of header and the source files will
result in a compilation error. User should ensure that the correct versions
of the header and the source files are used.

•  User/Integrator should ensure that same Ports/Pins are configured for
DIO Driver component.

•
The DIO functions shall be called only after PORT Driver
initialization, otherwise DIO functions will exhibit undefined
behavior.

•
Safety features related to Write-Verify are only available if
‘DioWriteVerify’ is enabled.

4.3.
Data Consistency

To support the re-entrance services, the AUTOSAR DIO module will ensure the
data consistency while accessing its own RAM storage or hardware registers.
The  DIO  module  will  use  SchM_Enter_Dio_<Exclusive  Area>  and
SchM_Exit_Dio_<Exclusive
Area>
functions.
The
SchM_Enter_Dio_<Exclusive Area> function is called before the data needs to
be protected and SchM_Exit_Dio_<Exclusive Area> function is called after the
data is accessed.
The following exclusive area along with scheduler services is used to provide
data integrity for shared resource:
• DIO_REGISTER_PROTECTION
The
functions
SchM_Enter_Dio_<Exclusive
Area>
and
SchM_Exit_Dio_<Exclusive  Area>  can  be  disabled  by  disabling  the
configuration parameter “DioCriticalSectionProtection”.

In the Sample Application all the DIO APIs are invoked in the following
sequence:
•  The API Dio_GetVersionInfo is invoked to get the version of the DIO
Driver module with a variable of Std_VersionInfoType, after the call of
this API the passed parameter will get updated with the DIO Driver
version details.
•  The API Dio_Init is invoked with a valid database address for the
proper initialization of the DIO Driver, all the DIO Driver control
registers and RAM variables will get initialized after this API is called.
•  The API Dio_WriteChannel is invoked to set the required level of a

particular channel. It sets the output level of the channel if that particular
channel is configured in output mode. If channel is configured for input
mode, Dio_WriteChannel has no effect.
•
The API Dio_ReadChannel reads the actual physical level of the
required channel. The level read for the input channel is actual
physical level of that channel if input buffer for that channel is
enabled. The level read for the output channel is actual physical level
of that channel if bidirectional control for that channel is enabled.
•  The API Dio_WritePort is invoked to simultaneously set the required
levels to all channels of a port. It sets the output level of the channels
which are configured in output mode, for the channels which are
configured in input mode, Dio_WritePort has no effect.
•
The API Dio_ReadPort reads the actual physical level of all the port
pins of a required port. The level read for the input port pin is actual
physical level of that port pin if input buffer for that port pin is enabled.
The level read for the output port pin is actual physical level of that port
pin if bidirectional control for that port pin is enabled.
•
The API Dio_WriteChannelGroup is invoked to simultaneously set the
required levels to group of channels of a port. It sets the output level of
the channels which are configured in output mode, for the channels
which are configured in input mode, Dio_WriteChannelGroup has no
effect.
•
The  API  Dio_ReadChannelGroup  reads  the  actual  physical  level  of
channel  group  of  a  required  port.  The  level  read  for  the  input  channel
group is actual physical level of that channel group if input buffer for that
channel group is enabled. The level read for the output channel group is
actual physical level of that channel group if bidirectional control for that
channel group is enabled.
•  The API Dio_MaskedWritePort provides service to set value of given port
with required mask.The Dio_MaskedWritePort function shall set the
specified value for the channel in specified port if the corresponding bit in
mask is ‘1’.
•  The API Dio_FlipChannel reads the level of the channel and invert it,
then write the inverted level to the channel if the channel is configured as
output channel and the function shall have no influence on the physical
output if the channel is configured as input channel.

•  Open a Command window and change the current working directory
to “make” directory present as mentioned in below path:
“X1X\P1x\common_family\make\<Compiler>”

Now execute batch file SampleApp.bat with following parameters:

SampleApp.bat dio 4.0.3 <Device_name>
<Device_name> can be 701304, 701305, 701310, 701311, 701312,
701313, 701314, 701315, 701318, 701319,
701320, 701321, 701322 and 701323.

After this, the tool output files will be generated with the configuration as
mentioned in App_DIO_P1M_<Device_name>_Sample.arxml file
available in the path:

•  “X1X\P1x\modules\dio\sample_application\<SubVariant>\<AUTOSAR_versi
on> \config”

•  After this, all the object files, map file and the executable file Sample.out
will be available in the output folder
(“X1X\P1x\modules\dio\sample_application\<SubVariant>\obj\<Compiler>”
in this case).

•  The executable can be loaded into the debugger and the sample
application can be executed.

Remark  Executable files with ‘*.out’ extension can be downloaded into the target
hardware with the help of Green Hills debugger.

  If any configuration changes (only post-build) are made to the
ECU Configuration Description files
  “X1X\P1x\modules\dio\sample_application\< SubVariant >
  \<AUTOSAR_version>config \ App_DIO_P1M_701318_Sample.arxml”

The database alone can be generated by using the following commands.

make –f App_DIO_P1M_Sample.mak generate_dio_config
make –f App_DIO_P1M_Sample.mak App_Dio_P1M_Sample.s37

After this, a flashable Motorola S-Record file App_Dio_P1M_Sample.s37 is
available in the output folder.
