PARAM ERROR in CANBUS Data transfer!!

[VPras]

Hi,

I'm trying to send data from STM32F767Zi to another node using CANBUS protocol....it starts sending data every second and at other node i can get data, but all of a sudden data stops transmitting,when i debug i finding HAL_CAN_ERROR_PARAM.

what could cause the error and how do i resolve it!!

Thanks,

Hello,

Did you generate a STM32CubeMx project ?

I suggest you to inspire from the CAN examples under the STM32F7 cube firmware package: STM32Cube_FW_F7_V1.15.0\Projects\STM32F769I_EVAL\Examples\CAN

This may helps you on your application.

Best Regards,

Yes i have used the one which was in the firmware package.In that sometimes i'm getting that above error.

Please let me know how to solve this.

Thanks

Seen a couple of reports of this, you'll have to debug into the HAL library code to understand what fields/parameters it is objecting too, or what peripheral state is causing this to flag.
