Can you please confirm that you can't build an fs greater than 2G, also check you local fs to make sure oyu have space. 18107 3 marc.ferland 2012-01-12 09:16:15 +0000 I tested mkdosfs from poky master branch and it works as expected. I was able to create a file larger than 2GB. Running the exact same command from the edison branch fails as described earlier. Problem solved! Thanks! 18108 4 nitin.a.kamble 2012-01-12 09:33:56 +0000 I guess upgrade to the newer version has brought new features solving the 2GB barrier. Closing the bug now.
