CCS/TMS570LS3137: how to configure gio pins (pin no 89 and 90 )of tms570ls3137 for can port 1 in halcogen and write the code in ccs?

Hello,
From the following link you can download Datasheet and Technical Reference Manual: www.ti.com/.../TMS570LS3137

You can use HALCoGen to start new project. When starting new project, specific MCU has to be selected. Then you can configure modules for your specific needs. For example if you want to use SPI4 module you have to do as follows:
- Open Driver enable Tab. Uncheck Mark/Unmark all drivers and check Enable SPI4 driver;
- Go to PINMUX tab. Check SPI4 box. This will make coresponding pins to used by SPI4 module. For example pin 25 will be used as SPI4CLK;
- Go to SPI4 Tab. Configure SPI4 module according to your needs. Set all unused signals in SPI4 module to be GIO (this can be done in SPI4 Port under SPI4 Tab).
- Go to File menu and select Generate code. HALCoGen will generate all needed configurations and API's.

More details you can find here: training.ti.com/hercules-how-tutorial-using-halcogen
At the same place you can find training videos for using modules as well.

Under HALCoGen install folder, examples are available as well. In HALCoGen Help (Help menu) you can see how to configure HALCoGen for using examples.


Best regards,
Miro

thank you...

i have another question,

in datasheet we observe 89 and 90 as can 1 tx and rx  and also it can be used  as gpio pins, so my question is two parts ,

a) how to configure pin 89 ,90 as can port 1 tx and rx?

b) how to configure pin 89 ,90 as gpio?

i know this process of configuring 

/** @example example_canCommunication.c
* This is an example which describes the steps to create an example application which
* configures two can nodes 1 and 2 and starts a communication with a sample data chunk.
* CAN 1 and CAN2 must be part of CAN network
*
*
* @b Step @b 1:
*
* Create a new project.
*
* Navigate: -> File -> New -> Project
*
* @image html example_createProject.jpg "Figure: Create a new Project"
*
* @b Step @b 2:
*
* Configure driver code generation:
* - Enable can driver
* - Disable others
*
* Navigate: -> TMS570LSxx /RM4 -> Enable Drivers
*
* @image html can_enabledriver.JPG "Figure: Enable CAN Driver"
*
* @b Step @b 3:
*
* Configure CAN Baudrate:
*
* Navigate: -> TMS570LSxx /RM4 -> CAN
*
* @image html can1baud.JPG "Figure: CAN1 BaudRate Configuration"
* @image html can2baud.JPG "Figure: CAN2 BaudRate Configuration"
*
* @b Step @b 4:
*
* Configure CAN MessageBox:
*
* - Configure CAN1 , MessageBox 1 -- Activate and Enable TX
* - Configure CAN2 , MessageBox 1 -- Activate and Enable RX
*
* Navigate: -> TMS570LSxx /RM4 -> CAN
*
* @image html canCommunication1.JPG "Figure: CAN1 MBox Configuration"
* @image html canCommunication2.JPG "Figure: CAN2 MBox Configuration"
*
* @b Step @b 5:
*
* Copy the source code below into your sys_main.c or replace sys_main.c with this file.
*
* The example file can also be found in the examples folder: ../HALCoGen/examples
*
* @note HALCoGen generates an empty main function in sys_main.c,
*

is there any specific configuration of pin no 89,90 to work as can or gpio wrt halcogen?

thank you for clear explaination.
