i.MX 8M Mini QuadLite. Floating Point Unit (FPU) Support

[mklnc]

Hi,

We're using MIMX8MM5CVTKZAA, i.MX 8M Mini QuadLite processor with quad core Arm Cortex-A53.  There is FPU support on the Arm Cortex-A53 MPCore™ Platform side, right? 

While FPU support in Quad Core A53 CPU is mentioned in the i.MX 8M Mini Applications Processor Datasheet document, FPU support is mostly mentioned in M4 CPU in the i.MX 8M Mini Applications Processor Reference Manual document.

Could you please check chapter 4 of the i.MX 8M Mini Applications Processor Reference Manual?

Thnx,

Merve

A53 cores in i.MX8M series have FPU.
Please note that you need to pass "-mfloat-abi=hard -mfpu=fpv4-d16" to the compiler to compile code using FPU features of the core.
