Hey Henno made a fix for this (5bbf7282 at ska-sa github repo)
Unfortunately, we did a clean-up of our repo and moved files around a while back so that trying to merge Henno's commit into casper-astro throws an error :( To make it work means making the changes we made, which removes support for iBOBs and BEE2s (and changes a few other things). I (mostly accidently) updated the casper-astro repo so that this happened but have since reversed this as it will probably create a fair amount of confusion. (We will have to think about this again closer to the casper workshop) So, we will have to redo Henno's mod, or use the ska-sa repo.
