    Hello,

    We don't have a code written for TMS570LS1224. But you can download the example code for  TMS570LS3137 from here:

    You should setup the TMS570LS1224 device (clocks, pinmux, etc) and after that reuse the driver from the example.

    Hi,

    Thanks for reply.

    I imported that code into ccs and changed the MCU from TMS570LS3137 to  TMS570LS1224 in properities and built. Please help me how to change the 

    pinmux and clock configurations . please can you mention the steps.

    thanks and regards,

    Hello,

    Sorry, I've missed the LaunchPad you are using. TMS570LS1224 does not have a FlexRay module.

    On TMS570LS1227 FlexRay module has dedicated pins. So, you don't have to set PINMMRs to use FlexRay.

    Hello,

    You have to create a new project to use TMS570LS1227. After that you can use HALCoGen to set all other modules you are using. HALCoGen does not have support for FlexRay module. Because FlexRay module on TMS570LS1227 has dedicated pins you don't need to change PINMMRs regarding FlexRay. Keep on mind that FlexRay module needs transceivers for connection between 2 devices. You should provide FlexRay with 80MHz from VCLKA2. I'll forward you question to our FlexRay expert for more on setting FlexRay module.

    Best regards,

    Hello,

    As Miro said, you need flexray transceiver to build flexray network. It is better to use PLL2 as the clock source of VCLKA2. The flexray modules have their dedicated pins which are not multiplexed with other signals.
