Hello Mohamed, Internal secondary power supplies (that generate 1.0V, 1.5V,
1.8V) on the 10393 board are constantly monitored and shut down if any of them
drops below threshold. When 5.0V is turned on, even with no load it charges
capacitors and it causes extra load on the primary 3.3V, so either 3.3V itself
or one of the secondary ones for the short time drops below the limit. It is
possible to modify the driver to temporarily disable power fault detection,
turn 5V on and then re-enable detection. But as your camera works with 10385
and power extra load for turning 5V is small makes me suspect that there is a
problem with 3V power source - it is close to the lower limit, or the wires are
long, or smth. else. So the camera can reset itself at later stages (turning on
streaming, or recording to SSD or anything else. Andrey ---- On Thu, 13 Dec

when the board tries to turn on 5V and fails. Try: * disconnect sensors if any
connected * another power supply (how do you power the board? direct 3.3V or
48V via 10385 board?) * another power cable On Thu, Dec 13, 2018 at 1:50 PM

tried replacing the devicetree.dtb file in the nand folder from
elphel393_20180511 with the one you sent. I tried the
ipaddress/update_software.html tool again but nothing changed. When I log into
the elphel from minicom and try ifconfig I still only get the local address at
127.0.0.1. This is on a Rev C board. Do you have any other ideas? Also I meant
to send the previous email from my Redzone email so I'll CC myself to this

Subject: Re: [Elphel-support] Elphel 393 Nand upgrade Hi Mohamed, I think
it's not related. Most likely you need an updated device tree (devicetree.dtb).
The newest boards are revC - they have a different PHY reg address compared to
revB (and older). The recovery cards came with updated devicetree - and so, the
network is working. The revision letter is printed near the network connector
on top of the board. For revC - try devicetree.dtb from the attachment.
fix_net_config.tar.gz - just moves network configuration from
/etc/elphel393/init_elphel393.py to /etc/network/interfaces which is a more
conventional place for linux. And it will be included in the next release. I'm
having trouble upgrading the NAND memory on an elphel 393. I've tried it with
multiple boards. I used the ipaddress/update_software.html tool. When I flash
the board, I shut it down, remove the uSD card, and reboot it. But it doesn't
boot up correctly. I'm able to log in on minicom but when I try ifconfig I find
that the board doesn't have an ip address. Do you know how to resolve this
issue? I noticed there's a recent upload at community.elphel.com/files/393
called fix_net_config.tar.gz. Is that related to my issue? Thanks, Mohamed
