Thank you for reply, but I'm already doing this... as I wrote in my latest

"Everytime, I recompile FPC with relative options (erasing old compiled
arm-android units) and edit relative project parameters, e.g.:

project->project options-> Other-> -CfSOFT -OoFASTMATH -CpARMV6

This works well.

project->project options-> Other-> -CfVFPV2 -OoFASTMATH -CpARMV7A

This doesn't work."

So, it always works with -CfSOFT (armv6 or armv7a), but never with
-CfVFPV2, -CfVFPV3, -CfVFPV3_D16, etc
