19:27 <Lyude> Anyone know if it's possible to get uboot working for the khadas vim2 with working watchdog support?

20:54 <Lyude> sweet, figured it out: mw 0xc11098d0 0x3245dc0; mw 0xc11098dc 0x0; mw 0xc11098d8 0xFFFF

21:02 <xdarklight> Lyude: for mainline u-boot you can probably port the Linux watchdog driver to u-boot with little effort

21:04 <Lyude> xdarklight: I figured as much; but I don't really feel like possibly breaking uboot on this board since I think actually fixing that would require taking it out of it's case so I could join the right pins to get it into mregister mode

22:25 <Lyude> So: does anyone know how one would go about controlling the fans on the vim2?

22:26 <Lyude> and additionally; has anyone actually got the emmc working on the vim2 with a mainline kernel?

22:29 <xdarklight> Lyude: https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/amlogic/meson-gxm-khadas-vim2.dts#L52 - there's a gpio-fan node already

22:30 <xdarklight> the first value of each tuple is the fan speed, the second value is the "level" (0 = off, ..., 3 = full speed)

22:32 <Lyude> ahhh; so am I supposed to modify those values? going off /* Dummy RPM values since fan is optional */

22:35 <xdarklight> yep (haven't tried it myself though since I don't have a fan for my VIM2)

22:36 <xdarklight> since there's only two GPIOs you're limited to four levels (0..3), so all that's missing is the correct fan speeds for each level for your specific fan

22:36 <Lyude> neat; I'll try it out. no daemons or anything needed in linux?

22:37 <xdarklight> shouldn't be needed AFAIK, the temperature targets are configured here: https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/amlogic/meson-gxm-khadas-vim2.dts#L107

22:41 <Lyude> sorry for all the questions but; hitting another problem, it seems like every now and then the ethernet on this board will cut out in this strange way where it stops responding to RX, unless you do something to make the board do TX

22:42 <Lyude> in which case so long as the board is doing TX, RX works fine

22:42 <Lyude> but if it stops then it stops responding again'

22:45 <Lyude> chewitt/narmstrong: you seen anything like this? ^

22:46 <xdarklight> what kernel version are you running?

22:46 <xdarklight> there was an stmmac fix that affects all Amlogic SoCs (newer than Meson8)

22:54 <Lyude> xdarklight: 4.19rc7

22:54 <Lyude> also made a forum post https://forum.khadas.com/t/ethernet-connectivity-issues-with-4-19-rc7/3006

22:54 <Lyude> if you've got any patches I can try them out

22:56 <xdarklight> hmm, 4.19-rc7 should already have 8fce3331702316d4bcfeb0771c09ac75d2192bbc

22:57 <Lyude> let me verify I've got that commit in this repo

22:57 <Xogium> very offtopic but, does anyone here knows if there is a wiki for mainline progress on porting SoC like armada-37xx to mainline ?

22:58 <Xogium> either kernel or u-boot, I mean

22:59 <Lyude> xdarklight: yep; looks like it's in my kernel

23:00 <xdarklight> Lyude: try adding "eee-broken-1000t;" to the PHY node here: https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/amlogic/meson-gxm-khadas-vim2.dts#L261 (just like on Odroid-C2: https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts#L146 )

23:01 <Lyude> xdarklight: alright; will rebuild kernel (need to for unrelated reasons) and dtb and see how that goes

23:02 <xdarklight> original description why it was added to Odroid-C2: https://patchwork.kernel.org/patch/9528915/

23:04 <xdarklight> I'm calling it a day. good night!

23:18 <Lyude> thank you for the help xdarklight, you too!

23:47 <Lyude> xdarklight: btw for when you get back on, might be a bit too early to tell but I'm pretty sure I already see a dramatic difference on the ethernet performance with that option in the devicetree
