No. If you have an sdcard inserted at boot it will always load the first and second stage boot loaders from eMMC, but it will always look to the first partition on the sdcard for uEnv.txt. The only exception is if S2 is depressed at boot time, then the first and second stage boot loader will be "attempted" from the sdcard first, but uEnv.txt will still be expected to exist on the sdcard. Many people ( yours truly included ) have in the past bemoaned this behavior of uboot. When having a blank sdcard inserted at boot.
