Subject: Re: targetinstaller in matlab R2011a

Target Installer first became available in R2012a so it is not available prior to that release. 

This summarizes prior release support for Beagleboard - and shows what you would need for that support in R2011b. Note that the support is different between releases, but if it is sufficient for you, then great.

Good luck,
