R2017b AUTOSAR not writing provided ports at initiatialization phase

I am trying to write a constant value of 0/false at the initialization phase in AUTOSAR. It is not written to the output port as expected. I was able to do this while using ert.tlc.

Simulink prevents writing 0 / false at the time of initialization for AUTOSAR because the initialization of the output block depends on the Runtime Environment (RTE).

Hence, a setting in Code Generation pane (optimization) of Configuration parameters in Simulink, known as "zeroExternalMemoryAtStartup" is checked by default for "autosar.tlc".

This setting removes root level I/O zero initialization.This can not be unchecked in "autosar.tlc". It can be unchecked in "ert.tlc".

Hence, the generated code does not write to "Outport".
