Hello,
Can someone help me to understand what is the issue with the failing builds?
The sbgECom driver is not built by default and the two minor fixes I did should not have any significant impact on the FLASH.
Thanks in advance.

Hello @tolesam I have a question. Does this PR intend to be used with the Ellipse Series, Ellipse 2 Micro Series, or both?

I'm interested in SBG products.

Hello @saengphet,
It's intended to be used with all SBG Systems' INS products.
Feel free to give us any feedback about it, we'll be happy to help you with our products' integration with this driver.
