Adrian Cable 2 December 2, 2019 Hi, Using the latest Armbian release (19.11.3) on OPi Zero (512MB, board revision 1.5) I have a strange issue. On kernel 5.3.x, Ethernet connectivity drops sporadically, around once every couple of minutes, for typically 10 seconds or so and then recovers. When the drop happens, a ping from another machine on the network produces 'no route to host' - then after around 10 seconds or so the network comes back up. The OPi Zero continues running normally during the 'outage', without functional network access. There is nothing in the dmesg log when this happens. Switching to kernel 4.19.62 from armbian-config, everything works perfectly. Back to 5.3.x, the issue starts again. Has anyone seen a similar issue and/or has a fix? Thank you! -Adrian Board: Orangepi Zero 0 Share this post Link to post Share on other sites
dolphs 22 December 2, 2019 we're talking about the OPi Zero LTS here? Could you try kernel 5.4.x instead of 5.3.x please ?

Adrian Cable Topic author 2 December 3, 2019 @dolphs - actually this is the "original" (non-LTS) OPi Zero. I believe I tried 5.4.x and had the same issue, but will double check. -Adrian 0 Share this post Link to post Share on other sites
Werner 141 December 3, 2019 If you do not need any special features of 5.3.x for your OPi you should stick to 4.19.x for now since 5.3.x is EOL already (4.19 is LTS) and kind a heavily patched anyways to support the SBC quite well. 0 Share this post Link to post Share on other sites
Adrian Cable Topic author 2 December 4, 2019 Yes - 5.4.1-sunxi #19.11.3.336 gives the same problem. Happy to stick with 4.19.x @Werner, but I have some OPi Zero LTS boards on the way, and my understanding is that the thermal sensor doesn't work with 4.19.62, but does work with 5.4.1. Is that correct? -Adrian 0 Share this post Link to post Share on other sites
Werner 141 December 4, 2019 Never really tested that. I know that I can grab the CPU temp from armbianmonitor. 0 Share this post Link to post Share on other sites
Adrian Cable Topic author 2 December 8, 2019 @Werner - are you saying that you get correct thermal readouts with armbianmonitor on OPi Zero LTS? I definitely don't!

Werner 141 December 9, 2019 Misunderstanding, I have a non-LTS board. 0 Share this post Link to post Share on other sites
