Hello Cheng, It seems from 37000 feet (commercial plane altitude) view that you do not have the following: [1] Appropriate Linux drivers for your W83627dhg superIO enabled in .config (make menuconfig options); [2] These drivers (maybe) are missing from your Linux distro; [3] If drivers are there, something fishy with these drivers, something with them is not right/correct.
I have couple of questions here: [1] Which Linux distro are you using? [2] Could you attach your kernel .config file? [3] Could you attach your dmesg traces/records? Thank you, Zoran On Fri, Jul 22, 2016 at 12:14 PM, cheng yichen <[email protected]> wrote: > Hi all > > My platform is braswell SOC with W83627dhg superIO.
