Hey Rob,
Did you use bmaptool to write the image to your SD card? I ran into the
same issue when using bmaptool. I switched to using dd instead and that
fixed the issue.
Figure out the underlying issue, don't use dd. Seriously, dd eats hard
drives if you make a typing mistake.

Hi,
I'm having some issues with my E310 related to booting up the file system
(UHD 4.1 file system loaded using bmaptool). Any help appreciated!
- Issue 1: during boot up, E310 linux fails mounting the /data
partition and consequently doesn't configure the Ethernet correctly (such
that I can't login via ssh) (see below startup log from console window).
- Note that I can look at the micro SD card on my Ubuntu host and I
see 4 partitions: /uboot, /data, & the 2 OS partitions. Everything looks
OK.
- I'm starting to suspect a bad micro SD card, but I don't have
solid reasoning for that.
- Issue 2: when I'm in this failed startup state, I can use "ip addr
add" to configure the eth0 device but I can't figure out how to restart the
sshd so that I can ssh into it (note I can ssh out just fine after setting
the IP addr). Does anyone know how to do so?
- Issue 3: I can't figure out how to set the real-time clock. If I
run "date" after bootup, it shows "Aug 6". I can fix this, but upon
reboot, it is back to "Aug 6". If I run "hwclock", it says it can't find
the hwclock. Does anyone know how to set the time in a non-volatile way
such that it won't be "Aug 6" after a power cycle.
