No idea what you mean regarding
fpcopt=set default as is explain on text which include it
Could you explain a bit more (exact messages/references to documentation etc).
You mean that you need to set ARMHF mode? Yes, ok, but in that case I suggest you read the fpcup wiki page on ARMHF compilation and use the correct section in the ini file (described there).
If necessary you can copy the section into a file of your own, edit it and use that.
That makes it easier to use.
Note that (with fpcup and also with regular fpc sources), ARMHF is only supported with FPC trunk (2.7.1) so make sure you set --fpcurl to the correct value. (--fpcurl=trunk IIRC, please see the fpcup wiki page for details).
so it did not work again
I and others are not mind readers. Please post exact error messages so we can understand what went wrong...
