I just built commit 2a82ec77d27e "Prepare v2015.01-rc2" and both eMMC and SD appear to work. Do you have a valid partition table on the eMMC? If you installed L4T there rather than partitioning it yourself, note that L4T uses a non-standard "tegra PT" partition table format. Some newer versions of L4T also include a backup GPT that makes some of the partitions available in a more standard way, but IIUC there's never a primary GPT. I don't recall if the version of L4T for Beaver was new enough to do even that though. Your best bet is to use standard tools to install a complete GPT and then install a Linux distro on top of that.
