DRA829V: Bus Sniffing Support

Islam Hassan

Part Number: DRA829V

I am using the following SDK: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/06_02_00_21/index_FDS.html for Jacinto 7 platform, it contains Eth driver implemented according to AUTOSAR specification.
I checked the concept of integrating Eth with AUTOSAR environment here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/mcusw/mcal_drv/docs/drv_docs/ug_ethvirtmac_top.html.

There is an application case that the J7 target will sniff the Ethernet bus in virtual MAC mode.

My question is if its possible to sniff the bus using virtual MAC mode and passing any frame to EthIf module and how to get the destination MAC address while passing the frame for Eth driver to EthIf.

Hi,

The Destination MAC address is populated in each eth frame header, Eth_FrameHeader.dstMac.

We recommend you to implement your own customized change in MCAL driver to support that.

TI MCAL driver will follow AutoSAR specification without adding customization.

Stanley

Hi Liu,

Thank you for the answer, but I need to clarify if the Ethernet driver in virtual MAC mode will pass all the received frames with any destination MAC address or it will filter them , is there any API will be used to enable all the frames to be received.

Thanks,
