OS compatibility between BBB and BBG?


We are currently using the BBB in our product, and would like to switch over to BBG. We have our own built OS we are using, and all is fine and well with the BBB. Should we move to BBG, will we need to consider changes to the linux kernel? Or are the two designs compatible with the software?

Also, the main reason we are moving to BBG is that it is lower cost, and the BBB seems not to be passing our EMC/FCC testing. We have read that the BBG may likely have significantly lower emissions… can anyone offer their experience here?

Thanks in advance!
