How do I choose a double precision hardware FPU in the MCUXpresso project settings?
The FPU type selectors are confusing and does not seem to match with ARM documentation.
I need hardware double-precision floating point.
On Arm's documentation, the option for double precision is given as FPv5-DP-D16-M, and the MCUXpresso does not let me choose that.
is correct for i.MX RT parts with double-precision FPU.
For those with only single-precision (i.MX RT 1011) the FPv5-SP16(Hard ABI) can be used instead.
