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.

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,

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.
