Dear Sebastian,

I think that my BSP code is correct. I attached this.

This code was made for referencing FreeBSD's i.MX6Q BSP code.

I guess that my issue is related with additional i.MX6Q system configuration.

Best Regards,

I don't have an i.MX6Q. I have two i.MX7D boards:

The i.MX6Q uses a Cortex A9. We already have SMP support for this core on other BSPs (Xilinx Zync, Altera Cyclone V, Realview). You only have to implement the _CPU_SMP_Start_processor() function. The code for this is available in FreeBSD for example.
