CAN Frame Drop

We are using a custom board which has a iMX6 Solo processor which runs Android KK. We are trying to receive burst of CAN frames from another device. It seems that, there is at-least one frame getting dropped in the iMX6 side but the CAN bus analyzer could receive the missing frame. Checking the Overflow and error registers had no flags being set. What may be the cause of the issue. This issue is particularly seen when a frame burst of 15 occurs. What could be the cause of the issue?

Processor: iMX6

OS: Android KK

Hi Sudar

to narrow down issue one can try to build minimal configuration, without gui and

increase in application number of can data buffers.

Hi Igor,

We will look for the Sabre AI reference board then. Meanwhile, could you point out what could be checked now to debug the issue.

Hi Igor,

Thanks for the replay. We are having a SabreSD Quad Evaluation board and adding support for CAN interface. Could you point out the Logs and registers to see if the issue occurs.
