I am using Yocto Dizzy,1.7.7, build with the wand board and noticed that the GPIO mapping is incorrect for some of the pins, i.e. I can't output anything to them. This appears inconsistent with Dora release. For example GPIO191, is functional with Dora release but not on Dizzy release.
As I don't want to revert by build, what steps are necessary to correct the GPIO issue. Keep in my I am a beginner interms of embedded Linux.
