Hi,
I am using an Ubuntu image for the BBB rev c and am using this tutorial for 
manually putting together the SD card image rather than using the pre-made 
flasher image ( which is flashed onto the eMMC). This is because I tweaked 
the U-boot so that the environment is maintained in the eMMC rather than on 
an EXT4 file. In order to do that, I just hard coded the variables that 
would have been set by uEnv.txt into the default environment for testing 
purposes. Specifically, the following vars:
-uname_r= <my_kernel_version>
-enable_uboot_overlays=1
-uboot_overlay_pru=/lib/firmware/AM335X-PRU-UIO-00A0.dtbo

After getting it to boot successfully  from my SD card, I noticed that when 
running 'lsblk' I do not see the eMMC's partitions that I eventually want 
to write my environment to. This is what I see: 

NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
mmcblk0     179:0    0 29.7G  0 disk
└─mmcblk0p1 179:1    0 29.7G  0 part /

Why is it that I can't view mmcblk1 (the eMMC) as well as mmcblk1boot0 and 
mmcblk1boot1? Is it something that needs to be updated in fstab? 

I used an Ubuntu flasher image on the eMMC and when I boot from there, I am 
able to see both the SD card and the eMMC:

NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
mmcblk0      179:0    0 29.7G  0 disk
└─mmcblk0p1  179:1    0 29.7G  0 part
mmcblk1      179:8    0  3.6G  0 disk
└─mmcblk1p1  179:9    0  3.6G  0 part /
mmcblk1boot0 179:16   0    2M  1 disk
mmcblk1boot1 179:24   0    2M  1 disk

 but when I boot from SD I cant see the eMMC. I did not disable the eMMC 
overlay as it shows in the serial debug that it got loaded in. Not sure 
what I can do about this.
Thanks in Advance.
