Hello, Seth here. I know sometimes the errors come from a mix up in info. on the board. The eMMC needs to be almost "exactly" the same image, it can also be erased, if you are not holding down the S2 button on the BBB per each boot.
... The favoritism of the BBB is for using the eMMC bootloader over the SD Card bootloader if the S2 button is not held down until all LEDs are lit on the board. I have found this to be true to some extent. Now, I usually just erase the eMMC info. but you can set up the same image on the eMMC as is on the SD Card image. Anyway...you get the picture. eMMC gets high dibs on bootloader priority if both the eMMC and SD Card have images on them. Seth P.S. Is there a particular image you are using? Also, try to not use C9.io for compilation or updating/upgrading. There was something going on w/ C9.io in the past that I recall. I think their business just got bought out or something. Anyway, try from the command line/terminal instead. Things should work nicely.
