The out_of_box_1843_mss project uses "ti.targets.arm.elf.R4Ft" as the target in the XDCtool settings, but the can_slb18xx_mss uses "ti.targets.arm.elf.R4F".
I also see both aer4f and aer4ft libraries included in the can_sbl18xx_mss project.
What does the "t" mean? Does it matter which one I use when building for the AWR1843 MSS?
