Time Triggered CAN communication support

I am currently in a process of selecting micro controller for my project. Basically i need TTCAN support and i have STM32F746G Disco board with me. Now as per the ST reference manual i see that this is supported. Now my questions are...

  1. Is there any reference available for TTCAN implementation?
  2. If the HW supports TTCAN, can i completely rely on HW module?

ex: who will generate reference message(defined in TTCAN spec) ? HW or my SW?

3.Can i make STM32F746G as master of my TTCAN cluster ?

Unfortunately i could not find much details in the internet and the ST reference manual. If anybody has prior knowledge of working on this topic please do respond.

Thanks :| !!

Read the errata sheets. Since the first STM32 up to the STM32F76 there is an item:

"BxCAN time triggered mode not supported . "

Oh yes. I verified it. Thanks for saving my time and effort. BTW, is there any other MCU in ST which support TTCAN ?

Unfortunately, FDCAN does'nt serve the purpose !!.

do you know if ST has fixed this errata in subsequent HW releases? Ex: STM32F76. I cannot find any official Errata sheet for STM32F76x in ST websites.

CAN FD implemented in new STM32 MCU can be used as classic CAN, based on that you can use TTCAN.
