[Elphel-support] Elphel 393 Nand upgrade

[Elphel Support]

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.

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 Mohamed Morsy <mmorsy at redzone.com> wrote: No it does not boot from flash.

Does the same uSD card work with other rev B boards? On Thu, Dec 13, 2018 at 1:30 PM Mohamed Morsy <mmorsy at redzone.com> wrote: Hi Oleg, I'm having another issue with another Elphel. It doesn't seem to boot up completely. When I connect the USB cable, open minicom, and power on the Elphel, it starts booting up for 2 seconds then stops and minicom says "Cannot open /dev/ttyUSB0!" The last thing on minicom before it stops is: [    2.034545] elphel393-pwr elphel393-pwr at 0: Probing elphel393-pwr This is a Rev B Elphel running on a uSD card. Do you know what the issue might be?

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 chain.

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?
