[Elphel-support] Elphel 393 Nand upgrade

[Morsy, Mohamed K]

Hi Oleg,


I 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 chain.


Thanks,


Mohamed Morsy

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<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fcommunity.elphel.com%2Ffiles%2F393&data=02%7C01%7CMKM89%40pitt.edu%7C69e9fd539853460af0b808d65a21ddbc%7C9ef9f489e0a04eeb87cc3a526112fd0d%7C1%7C1%7C636795498844445600&sdata=nmNC%2B4fi8iv%2FKJk2i5mVpAEVZ4r1A5H%2FCS3woLV3%2Bhc%3D&reserved=0> called fix_net_config.tar.gz. Is that related to my issue?
