14:17 <apritzel> does anyone know what's the point of changing or adjusting a PMIC's DCDC frequency? Is that a trade-off between power-saving (using a lower freq) and smoother voltage/less ripples with higher frequencies?

19:27 <DarkNeutrino> apritzel: I got your mail. Will try it in about half an hour :)

19:34 <apritzel> nice, thanks!

20:38 <DarkNeutrino> OK lesson learned. Dont update your gentoo setup while you are on break :|

20:38 <DarkNeutrino> GCC did not like that update

20:38 <DarkNeutrino> Its compiling finally

20:47 <apritzel> DarkNeutrino: compiler your userland? :-D

20:48 <apritzel> btw, I just checked and there is a fixed, but customisable RTC LDO in the other PMICs as well, for instance the AXP803

20:50 <DarkNeutrino> apritzel: Well on gentoo nearly everything is compiled on host machine. Just that Mr martin the host owner didnt update some gcc dependencies and GCC was like "No. Segfault"

20:51 <apritzel> yeah, I know, "still compiling ..." was already a Gentoo meme before the term "meme" became popular

20:52 <DarkNeutrino> Yea :)

20:52 <DarkNeutrino> Does the latest today -next master compile ?

21:05 <apritzel> works for me, do you see any problems?

21:06 <DarkNeutrino> So far so good. Next from 10th didnt build

21:42 <DarkNeutrino> apritzel: So it boots just fine. And seems to work just fine as well. The kernel starts throwing out kernel panic but thats due to my uboot RAM setup. So from my side it looks good. Tho we should probably get junari to test it as well on their board and see if it behaves there as well :)

21:59 <apritzel> yeah, but more tests reports can happen on the list

21:59 <apritzel> thanks for checking!

22:00 <apritzel> do you reference the RTCLDO in your DT?

22:00 <apritzel> I mean via a separate fixed regulator? I guess not?

22:01 <DarkNeutrino> Nope.

22:03 <DarkNeutrino> The only fixed regs i have here are USB ones

22:08 <apritzel> I see, makes sense

22:09 <apritzel> I saw that the other AXPs with a "fixed" RTCLDO also fix a voltage, not sure we can do that

22:10 <apritzel> but maybe we can leave that voltage uninitialised, and set it in the DT (despite it being a fixed regulator)

22:10 <apritzel> I saw this being done in the other DTs, even though the voltage is additionally set in the driver

22:15 <apritzel> DarkNeutrino: argh, BIQU doesn't seem to ship a BSP image with an Allwinner boot0, do they?

22:15 <apritzel> I wanted to harvest the DRAM delay settings from there ...

22:15 <DarkNeutrino> afaik no.

22:16 <DarkNeutrino> They only provide OS images

22:16 <DarkNeutrino> But those are weird

22:16 <apritzel> well, they ship U-Boot in there, but it's mainline based

22:16 <DarkNeutrino> https://github.com/bigtreetech/CB1

22:16 <apritzel> which is good, normally, but we miss the board specific delay values

22:17 <DarkNeutrino> Yep mainline since uhmmm few weeks

22:17 <apritzel> yeah, that's where I was looking for the last few minutes

22:17 <DarkNeutrino> They were on old old one in previous releases

22:17 <DarkNeutrino> 2019 iirc

22:18 <apritzel> yes, just saw that, downloading the first one ...

23:09 <apritzel> well, the "first" one on *this* page is only half a year old, and is already a mainline based image

23:29 <DarkNeutrino> :(

23:30 <DarkNeutrino> I will try to grab some info from them ;)

23:37 <apritzel> I just need the first 1MB of an image file that would end up on an SD card

23:49 <DarkNeutrino> Well i meant more like i will try to grab the timings from the contact directly hehe

23:49 <DarkNeutrino> If they can share

23:49 <DarkNeutrino> Or if they have them
