Initialization time for Autosar

Vivian(MCU) Zhang

Hi,

My customer want to use Autosar on EV BMS system with TMS570.

As there's strict time for the communication with VCU by CAN after system reset, normal less than 500ms,  so we care about the initialization time for Autosar.

It typically will take how long time?

    Hi Vivian,

    Your questions has to be analyzed based on the Type of System design, Startup & Initialization routines, Baud rate configuration etc..

    From CAN AUTOSAR MCAL Drivers perspective, which typically TI ( Semiconductor Vendors ) provides would take like 35 usec ( assuming device runs at 180MHz) to perform CAN HW initialization and Message to Mailbox for transfer using MCAL API's like write Can_Init , Can_SetControllerMode, Can_Write.. Rest depends on the bus availability and Baud rate etc.

    Also other AUTOSAR SW layers timing details has to be analyzed, which must be checked with the BSW SW providers or customer may have their own.
