4.20.6.3. Error handling
4.20.6.3.1. Development Error Reporting
The module PORT depends on the DET (by default) in order to report development errors. Detection and reporting of development errors can be enabled or disabled by the switch PORT_DEV_ERROR_DETECT = STD_ON in the Port_Cfg.h
AUTOSAR requires that API functions shall check the validity of their respective parameters. These checks are for development error reporting and can be enabled or disabled.
4.20.6.4. Error Code
4.20.6.4.1. Development Errors
The errors reported to DET module are described in the following table:
Type of Error |

4.20.7. Used resources
4.20.7.1. Interrupt Handling
4.20.7.1.1. GPIO Interrupts
Individual channel Interrupt can be configured with particular channel and it’s being used to detect the rising/falling/both edge occurred on configured channel.
Bank channel Interrupt are the interrupt that can be configured with particular bank and it’s being used to detect the rising/falling/both edge occurred on all channels in configured bank.
Below are the four GPIO XBAR interrupts available.
GPIO Interrupt |
|---|
GPIO XBAROUT14 INTR |
GPIO XBAROUT15 INTR |
GPIO XBAROUT16 INTR |
GPIO XBAROUT17 INTR |
The above mentioned 4 GPIO XBAR interrupts should be mapped to Software ISR’s mentioned below:
For Individual Channel Interrupt: Port_Ch<n>Isr , here <n> is between 0 to 139.
For Bank Interrupt: Port_Bnk<m>Isr , here <m> is between 0 to 8.
These all four GPIO cross bar interrupt source can be configured either Individual channel Interrupt or Bank interrupt.
Each GPIO pin is interrupt capable and can be configured in PortDioConfig container in PORT Plugins as shown below.
The PORT module depends on MCU module for the configuration of Channel/Bank Interrupt. All above 4 GPIO interrupts should be configured by MCU driver before usage. McuGpioXbarIntrConfiguration container from MCU plugins can be used to do to the same.
GPIO interrupt API’s:
APIs |
Description |
|---|---|
Port_PinEnableIntrNotification |
This function is Non- Autosar based and is used to enable bank/channel GPIO Interrupts for particular channel |
Port_PinDisableIntrNotification |
This function is Non- Autosar based and is used to disable bank/channel GPIO Interrupts for particular channel |
Port_GetInterruptStatus |
This function is Non- Autosar based and is used to collect interrupt register value for each GPIO bank |
Port_ClearInterruptStatus |
This function is Non- Autosar based and is used to clear interrupt register for each GPIO bank |
Note
Mcu Plugins should be added with Port Plugins while Port configuration files generation.
Each used channel in PortDioConfig container should be configured as a GPIO with INPUT direction.
Please refer PORT Example Application to know more about GPIO Interrupt feature configuration and its usage.
4.20.7.1.2. Hardware - Software - ISR API name mapping
For interrupt notification, ISR is provided in PORT driver. The following interrupt is generated by PORT module. The supported ISR is a part of the Port_Irq.h file.
Following are PORT module ISR’s:
For Individual Channel Interrupt: Port_Ch<\n>Isr , here <n> is between 0 to 139.
For Bank Interrupt: Port_Bnk<m>Isr , here <m> is between 0 to 8.
4.20.7.2. Hardware-Software Mapping
4.20.7.2.1. GPIO Channels Mapping
AM261x have total 140 GPIO pins available which allocated from Bank A(Bank 0) to Bank I(Bank 8). Each Bank contains 16 channels except Bank I(Bank 8).
Bank I contains the 12 channels.

4.20.8. Integration description
4.20.8.1. Dependent modules
4.20.8.1.1. DET
This implementation depends on the DET in order to report development errors. The detection of development errors is configurable (ON / OFF). The switch PORT_DEV_ERROR_DETECT will activate or deactivate the detection of all development errors.
4.20.8.1.2. DEM
Note
Dem Event is enable only if $(Module_Name)DemEventParameterRefs is enabled.
4.20.8.1.3. SchM
If multiple AUTOSAR runnables have access to the same Data Store Memory block, the exported AUTOSAR specification enforces data consistency by using an AUTOSAR exclusive area. With this specification, the runnables have mutually exclusive access to the per-instance memory global data, which prevents data corruption. Beside the OS, the BSW Scheduler provides functions that PORT module calls at begin and end of critical sections. This implementation requires 1 level of exclusive access to guard critical sections.
The data consistency mechanism that has to be applied to an ExclusiveArea might be domain, ECU or even project specific. The decision which mechanism has to be applied by RTE / Basic Software Scheduler is taken during ECU integration by setting the Exclusive Area configuration parameter RteExclusiveAreaImplMechanism. This parameter is an input for RTE generator.
For PORT Module, data consistency and exclusive access to critical sections are required for the following sections as shown in the table below:
Exclusive Area Functions used |
PORT Function calling Exclusive Area |
Need for Exclusive Area |
Recommended Exclusive Area Mapping |
|---|---|---|---|
PORT_EXCLUSIVE_AREA_0 |
Port_SetPinDirection |
To protect against multiple access for shared resources |
ALL_INTERRUPT_BLOCKING : All interrupts should be blocked as this API’s can be called in the interrupts |
4.20.8.1.4. Callback Notification
Notifications:
As it is a configurable interface, the PORT defines notifications that can be mapped to callback functions provided by other modules. The mapping is not statically defined by the PORT but can be performed at configuration time. The function prototypes that can be used for the configuration have to match the appropriate function prototype signatures, described below:
PortDioInterruptNotification:
This is of type Port_IsrNotificationType which is defined in Port_Cfg.h file. This is called to notify the group about the completion of the requested conversion and availability of the conversion results.

Note
PortDioConfig container is specifically used only to configure the GPIO interrupt feature parameters.
To use the GPIO interrupt feature, user should configure the required GPIO channels in PortDioConfig container.
4.20.9.3. Steps To Configure Port Module
Open EB Tresos configurator tool and Select the Config Variant ( Precompile/Post-Build) and Device Variant ( Pin Package ) parameters
Go to Port Container tab and create a new container
Open the created container and go to PortPin container to create a portPin configuration. ( Multiple PortPin configurations can be created )
Open the created Port pin, and configure the pin parameters
Select the Port pin peripheral instance ( Mode ) which needs to be configured and accordingly select the Peripheral Signal. As per selected Signal, physical pin ID needs to be selected from the list
Configure the other parameters as per pin usage.
Open Port pin Mode tab and add the default port pin mode ( at least one mode is required for this field ). Other supported modes for that pin can also be configured if user needs to change the mode for the pin afterwards.
Configure the number of port pins in port container general tab
Save the configuration and generate the configuration.
4.20.10. Examples
The example application demonstrates use of Port module, the list below identifies key steps performed in the example.
4.20.10.1. Overview
Port Example:
Initialize clock using Mcu_Init()
Initialize port using Port_Init()
Configure Gpio Interrupt
Test Port Interrupt Functionality
Set Port pin direction of GPIOGH_120 to PORT_PIN_OUT using Port_SetPinDirection()
Read the Port pin channel level using Dio_ReadChannel()
Toggle the channel level using Dio_FlipChannel()
Verify the read result
4.20.10.2. Setup required to run example
PORT module is tested using CC board (PROC111E2).
4.20.10.3. How to run examples
4.20.10.3.1. Steps to build and run example
PORT example application demonstrating the MCAL PORT driver features is in folder <MCAL_ROOT>/examples/Port.
This application can be built from the root folder by giving gmake –s port_app PLATFORM=am261.
Once the build is completed we get a binary file, which is loaded in our controller and executed.
4.20.10.3.2. Configuration used to test this example
Pin configurations : Following pins are configured as a GPIO and used in example application to test.
