I'll think about it. Thank you!

Yes.

I'm sorry. I don't have it.
There is a SILK board of R-Car Gen2 in the office where I work.
But I can't go to the office now because of the COVID-19 problem. 
If I can go to the office, I'll bring home the SILK board.

Yes. I think so, too.
Since it is necessary to reduce the Image size for embedded use, I found
this problem when changing to a module and testing.
