TMS570LS3137: DIO and Port Configuration for MIBSPI5NENA

Niveditha Bangalore

Part Number: TMS570LS3137

Using the AUTOSAR_MCAL_TMS570LSx-05.30.00. The Issue is related to the Port/ DIO Configuration for the SPI5. MIBSPI5NENA(Pin 97) is used as a DIO - OutPut.

Port Mux config for this Pin is set to Default. In the PortContainer-SPI5 the Mode is set to DIO and the Direction set to OUTPUT, Default level is set to HIGH.

DioChannel for MIBSPI5NENA is configured in the DIO Configuration.

Dio_WriteChannel(DioChannelMIBSPI5NENA, Level) does not change level on the Pin. I see that SPIPC3 (0xFFF7_FC20) does not reflect the change in Level from Dio_WriteChannel.

By changing the SPIPC3 bit 8, the Level of Pin MIBSPI5NENA(Pin 97) changes. However, Dio_WriteChannel(DioChannelMIBSPI5NENA, Level) does not change the PIN Level.

Please note that a change in the Default level to LOW also is not reflected on the PIN. It stays at HIGH all the time.

Please check.

Hello Niveditha,

I will check the MCAL and come back to you soon.

Hello,

Is DioChannelMIBSPI5NENA the channel ID for SPI5NENA pin in your configuration? If it is not the correct ID number, you will not able to set this pin.

Please use DIO_readPort to read SPI5 port? or use Dio_ReadChannel to read SPI5ENA using the same ID, and check the return value.

Hi Wang,
Thanks!

Yes, DioChannelMIBSPI5NENA is a symbolic name I have used here for the representation. I have configured the Dio and Port as required and done for other Pins. I checked using the Dio_ReadChannel for the same channelId and I find that the return value does not change. It stays at STD_HIGH all the time for my project and it is the same on the Physical line too.

Do you need any more data like the generated files for Dio and Port to investigate further? Or can you check this directly with the AUTOSAR_MCAL_TMS570LSx-05.30.00?

Regards
Niveditha

Hello Niveditha,

I have forwarded your question to our MCAL developer. He will come back to answer your question soon. Thank you for your patient.

Hello Niveditha,

We need to refer the configuration files you'd used for Port and Dio.

Please share these files - Port_Cfg.h, Port_PBcfg.c, Dio_Cfg.h, Dio_PBcfg.c.

Hi,

Have attached the Port and Dio Config generated files from my project. DioPinSpi5_CAN1_WAKE is the PIN that is configured to use MIBSPI5NENA (Pin97) as a DIO. Let me know in case you need more inputs.

Hi Niveditha,

Our MCAL experts said they had regular conf call with vector. I think this problem had been addressed and solved.

Hi Wang,

I reconfigured the DIO and tested this. I figured out the intended method of the configuration.

It seems that the tooling (and generated files Dio_cfg.h and Dio_PBcfg.c) needs to configure all the preceeding DIO pins in the DioContainer irrespective of whether they are used as DIO or not to have as a place holder in Dio_ChannelCheckTable. For example in this specific case, to configure MIBSPI5NENA(Pin 97) from the Port container SPI5. Although, I use only MIBSPI5NENA, it is required to configure 7 dummy DIO channels under the DioPortSpi5 before configuring for MIBSPI5NENA.

You can close this issue.

However, this is not evident for the user. Please add descriptions in the MCAL Dio_UserGuide.

Regards

Niveditha
