Re: [Help-gsl] GSL in a microcontroller

[Sam Mason]

Hi Jorge,

I've only played around with very small 8-bit Microchip PIC
microcontrollers; very different from the sort of things you're
interested in, sorry!

Google suggests there are various ARM based development boards that
use the GNU tool chain, a few seconds on google points to the
following:

  http://www.openembedded.org/

It says it includes the GSL and has some hardware recommendations for
getting started.
