SK-AM62A-LP: Maximum supported regions in NSF4 plugin

Hi Viral,

I wanted to confirm if there is any limit on the number of regions we can create and tune in NSF4 plugin.

The number of regions is limited to 10 in the link below.

I tried with 3 regions (gain based) and it seemed that only 2 of them were being applied.

That depends on the gain values you have at run time.

Also can you please help me understanding how the gains of my sensor are mapped with that of photospaces (1 - 1024)?

This should be defined in the tuning tool documents as in the steps 0.1 EV.

You may refer to the code in the link below.

git.ti.com/.../parse_data.c

e.g., 1.0x sensor gain (EV=0) is mapped to "1" and 2.0x gain (EV=1) to "10".
