Dear NXP,

I am working on i.MX 6Quad SABRE-SD with Android 9. I developed the custom service to start OBD. But after some time the process closed by tomestone service.

Hello,

Developing custom Android services is out of our scope of support. Since is more related to the App creation than to our Android BSP. I apologize for the inconvenience this could give you.

Best regards,

Diego.

There is a temporary solutions to fix this problem to increase the buffer size.

FORTIFY: memcpy: prevented 255-byte write into 50-byte buffer

As per this content , I increased the buffer size.

Thanks & Regards,
