Sorry about this - this specific one is an issue I've already fixed. It's not to do with CS/etc at all (that seemed to be an nRF52 issue anyway?).
If you update to the latest from http://www.espruino.com/binaries/travis/master/ it should be fixed. I'll do a 2v06 release soon that should sort that out - or you can just use software SPI
