Ah, OK. I thought you provided some minimal software to use the capes you sold.
Was I wrong? In that case, sorry for bothering. I'll ask in the TI forum, although they don't seem the most knowledgeable engineers out there. Let's cross fingers and hope that I get lucky. Right now, I have this cape connected, but it's completely unusable to me, without the capability of booting to it :-( Thanks for the prompt answer!
