Assuming you downloaded u-boot from dropbox, we just found a regression that slipped into u-boot on Dec 6. I have updated the version in the dropbox to: http://dl.dropbox.com/u/14618236/u-boot-usrp-e1xx-2011.12-r1.bin All you need to do is copy u-boot onto the FAT partition and things should speed up quite a bit. This makes sure L2 cache is on before Linux boots. There is some discussion of how to properly turn it on at boot in Linux at the moment. This does not effect the factory file system. Thanks for reporting this! Philip _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
