ZMOD4450 Refriferation Gas Sensor closed source firmware

Hello,

I’ve purchased a few ZMOD4450 (Qwiic) (https://www.sparkfun.com/products/16677) sensors, and to program it I need some source files from Renesas (as stated in product page and in README.md on Github: https://github.com/sparkfun/SparkFun_Re … 4450_Qwiic).

Simple registration on renesas.com only gives access to the programming manual, but the firmware download is still locked. I also requested access specifically for the firmware archive, but got no answer for a week already.

Does anybody know how to get access to the firmware download? E.g Does Renesas require some specific information posted to the request form or is it normal for Renesas to review access request fr so long?
