Re: Debian 'armhf' (hard-float ABI) for Raspberry Pi?

<r>OK, I've got a Freescale i.MX53 Quick Start board on order from Digikey along with a handful of spare SD cards from Amazon.  I'll also order a SATA drive for the quickstart board, but I won't need it right away.<br/> <br/> To make progress creating a hard float optimized port of Debian for RPi, r...

Re: Fedora Remix or Debian?

<t>Hmmm.  As the RPi goes into volume production, I wonder if it would make sense to buy at least 10 of the little buggers for about $400 and NFS mount disk volumes from a fast central PC to accomplish builds on actual hardware.  Swap and the root file system could even be NFS mounted to save poundi...
