I've noticed the current Yocto firmware on Intel's download is version Yocto 2.1. Does this firmware release image include the latest Yocto-Core Fido 1.8 according to the YoctoProject.org? If not, would it be a good idea to flash with the latest update?
The Image of the Edison that is available Intel® Edison Board Download | Intel® Developer Zone is based on Yocto Daisy 1.6. Also, the Edison BSP is based on 1.6. I guess you could create another system build with Fido recipes but it would need much more additional work from your side because they would not be mapped to the Edison’s hardware.
