dhlii Posted March 6, 2017 Posted March 6, 2017 Looking for any means of finding a unique and permanent MAC address for opilites. Is there some kind of serial number or other unique number of any kind in an H3 SOC or in something on an OPI Lite board that could be used to derive a MAC ? As things currently are I either have to manually setup the mac for each board I build - in a conf file in /etc/modprobe.d or live with the fact that the board comes up with a new mac/ip with every boot.
tkaiser Posted March 6, 2017 Posted March 6, 2017 https://github.com/igorpecovnik/lib/commit/1b4c92e53ac2c6ff2a78ae44898e32e2f5b62902 We set a random MAC address on first boot in the beginning and this got fixed then months ago by a driver patch. If this is not enough to solve the problem please check my signature what should be required to properly 'report a bug' (checking logs on your own first and provide them for others to inspect)
dhlii Posted March 6, 2017 Author Posted March 6, 2017 I must have missed that. I am running Armbian 5.27/Linux 4.10 If that sets the MAC randomly ONCE that will do what I need. Thank you.
jernej Posted March 6, 2017 Posted March 6, 2017 That patch is only for legacy kernel. I don't think anyone bothered to make similar patch for mainline kernel. Don't get me wrong, it is not trivial, some kernel knowledge is required.
dhlii Posted March 6, 2017 Author Posted March 6, 2017 Then I guess I get to look at that, cause I have zero interest in the legacy kernel.
tkaiser Posted March 6, 2017 Posted March 6, 2017 Ok, mainline kernel. IIRC Martin Ayotte mentioned that setting MAC address from DT should work? If not, please feel free to send a PR with a patch against https://github.com/igorpecovnik/lib and please report back in any case how you solved it (adding the /etc/modprobe.d/8189fs.conf tweak back to firstrun script when mainline kernel is detected is IMO a valid option)

Don't get me wrong, it is not trivial, some kernel knowledge is required. I don't think anybody is interested in mainlining 8189es and 8189fs drivers at all. If these drivers were converted into platform drivers and DTs were patched accordingly with aliases then u-boot could set unique SID based MAC address automatically.
jernej Posted March 7, 2017 Posted March 7, 2017 IIRC Jeff Moine had some patches for wifi as well. Unfortunately, I didn't save his patches before he deleted them. Does anybody have his patches?

jernej Posted March 8, 2017 Posted March 8, 2017 Are you actually capable of downloading patches? I'm not. Were his patches at one point used by Armbian?

Only the Wi-Fi patch you asked for: http://web.archive.org/web/20170308163951/http://moinejf.free.fr/opi2/8189es.patch No idea about driver situation since I was 'Wi-Fi on Linux' hater up until just recently
zador.blood.stained Posted March 8, 2017 Posted March 8, 2017 Also this opens for me without using archive.org: http://moinejf.free.fr/opi2/8189es.patch
jernej Posted March 8, 2017 Posted March 8, 2017 Ok, that was not what I expected. I thought that at some point there was patch for mainline RTL wifi driver which added SDIO IDs and maybe few other things. I wonder if that would work or not, but it would take some time before I can test this theory. After all, it would be unproductive for Realtek to always completely redesign the chips.
