Quote from: lambda on January 27, 2015, 03:09:48 pmHi jomag,I'm using my imx233-olinuxino boards with openwrt (mainline kernel) and that seems to work ok: Uptimes about a year so far.I never bothered about sound, but the modules are there, so at least the drivers can be compiled on recent kernels successfully.HTH,Harald

All seem to behave well.I think the machine with the highest uptime has kernel 3.14.18 - I don'ttrack openwrt revisions.I'd recommend to either use the latest release or the latest trunk. Itwould be a lot of bad luck to pick a bad kernel and things generallyhave been improved a lot.About uptime: Maybe some issues people are seeing are actually problemsof the hardware: The bigger boards seem to be not quite noise immune.Put them togethe with some relays into a metal box and you will geta lot of crashes - often the watchdog recovers the board, but sometimeseven that fails. Put the relays in some distance to the board and addproper noise filtering and a -MINI can have good uptime.The -NANO seems to be more noise immune. Didn't see any crashes evenin harsh environments yet.HTH,Harald
