Thanks Jonathon,
This morning, I discovered that after writing the file system image
with bmaptool,
* if I immediately pull the SD card from the host card reader and
insert it into the E310, it boots up ok
* If I instead pull the SD card and re-insert it right away in the
host card reader (to force auto-remount), do nothing, then click
to eject the SD card and insert in the E310. It does not boot up!
The host (Ubuntu 20.04) must do something to the SD card by simply
mounting and ejecting the SD card. Perhaps it has something to do
with the Data partition being an expandable partition?
Any ideas on this? The reason for wanting to re-mount the SD card in
the host system right away is to configure the
/data/network/eth0.network interface to change it from DHCP to Static
IP. At first I speculated that re-writing this file on the host was
causing the issue, but later I determined that just the mount/eject
sequence causes the problem.
Also, any ideas on how I can fix the "date/time" so that it doesn't
always come up "Aug 6"?

According to the schematics, there IS an RTC chip on the E310, so my
guess is that the system image didn't include the driver for it.
Let me check with R&D.

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.

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).
o 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.
o 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.
