fTPM should work for both JP6.1(r36.4.0) and JP6.2(r36.4.3).
It seems something missing in the latest developer guide of JP6.2.
Please let me check this with internal.
that’s documentation erroneous, it might be the linkage problem. (not root cause yet)
please refer to fTPM documentation from r36.4 public release as temporary solution.
