Unfortunately, wrong.

ISA will affect the assembly and binary patterns, also some basic
stack operation.
You cannot run v1 v1f binary on the adp-ag101 board.
You also cannot run v1f on the chip which didn't have floating point unit.
So, you cannot run v1f binary on adp-ag101p board.
There will decode floating related ISA as non-floating point then lead fault.

The capability is listed as follows.
adp-ag101: v0 binary only.
adp-ag101p: v0 and v1 binary.
adp-ag102: v0, v1, v1f
