<cardboard64> for sd-booting, what should the partions be?
<KotCzarny> check the wiki
<mru> doesn't matter
<KotCzarny> there is a page for that
fl_0 has joined #linux-sunxi
<KotCzarny> mru: first meg has to be unused
<KotCzarny> it's the only req though
<mru> drop the u-boot image at 8k offset
<cardboard64> should it be an 1 mb zone with the spl then rootfs, or do I need a fat partition with uboot/uImage?
<mru> partition as you see fit beyond that
<KotCzarny> spl/uboot is written to raw disk
<KotCzarny> not on partition
<mru> u-boot understands partition tables and doesn't care
<KotCzarny> mru, would spl load uboot from partition?
<mru> it can, but that's not usually done on sunxi
<KotCzarny> cardboard64: read again, first 1MB is raw disk
<KotCzarny> and in this space you write spl+uboot
<mru> the 1M size is arbitrary
<KotCzarny> mru: safe space
<mru> as long as it's enough to fit u-boot
<cardboard64> ok, I did it so. I'm trying to understand why my tablet is not booting at all
<KotCzarny> cardboard64: bad spl+uboot ?
<KotCzarny> wrong write offset?
<mru> wrong u-boot config
<mru> broken sd card
<mru> could be anything

<lebomees1> wau libv: nice to see you online on IRC, and by apologease about my psychotic past time behavior.
<lebomees1> j have since then landed into more maintainable solutions :) vastly simplified versions. I am thinking if there is some community that lets me to participate in doing some code, or i have to deal with only bitcoin this time?
<lebomees1> fdo gangstas do not let me to touch and get close to anything, so perhaps i'd ally with libv.
<lebomees1> it is pretty bad madness that most the low-end and mid-end hw has absolute nonsense code, even i get critisized caus of that, even though i am not maintaining this madness.
<lebomees1> libv: can you try to talk with me? do you know if there are some dangers involved by uploading the code for people that actually performs good as well, will something in the world go proportianally out of shape? have someone been doing some analysing over that
<lebomees1> ?
<KotCzarny> the only place to 'upload some code' is sending it to linux mailing list, i guess
<KotCzarny> with proper style and attributions
<KotCzarny> meaning, gpl only
<lebomees1> well, even though i do not have all the hw present of course, some chips i have still, i really landed on easily maintanable performance path for AMD graphics cards.
<lebomees1> so far only, and am trying to get focuesed to flesh out some of my compression inventions or ideas.
<lebomees1> all the committing process needs a bit time allocated from me though to study the process indeed though
<lebomees1> KotCzarny: I finally almost understood how to access sw controlled virtual registers from inside the 32-bit registers cell, with checksumming techniques

<lebomees1> something is looking to be highly wrong, i do not even understand what anymore though, am i so kinda annoying to all of the humans or what, or are there some threats involved pushing real code
<lebomees1> or are just some guys insulted cause of someone knows better how to handle things, however i can not do everything alone myself
<lebomees1> bye

<R0b0t1> alright, I have an allwinner h2(+?) based board, and I'm trying to change the i2c bus speed
<R0b0t1> I can't find it in the dts
macc24 has joined #linux-sunxi
<R0b0t1> I see the i2c device node, but no prescaler
tuxd3v has quit [Ping timeout: 260 seconds]
<[TheBug]> R0b0t1: just a quick reminder, people here are in all differnt time zone, so sometimes person who knows your answer will not be around for a while -- feel free to hang out here for a while and as someone is able I am sure they will try to answer
<MoeIcenowy> R0b0t1: check the I2C controller's DT binding
<MoeIcenowy> it's Documentation/devicetree/bindings/i2c/marvell,mv64xxx-i2c.yaml in the kernel source
<MoeIcenowy> (the file is named so because Marvell bought I2C controller IP from the same vendor with Allwinner
<mru> that's an annoying habit people have
<mru> naming drivers after some random chip that happens to use the hardware block
<willmore> fALSO, deranged chatbot?
<fALSO> dont know
<fALSO> it was very weird
<fALSO> i kept quiet because i was afraid :-P
<R0b0t1> MoeIcenowy: Ah okay it looks like I can just throw in clock-frequency in the dts then, I was worried I might need to change the reg value or something
perr has joined #linux-sunxi
<willmore> mru, if the vendors would just say "this is a DW IIC controller", that'd be great, but we generally only find out years later.
<willmore> But, then you get vendors who not only won't say who's IP it is, but intentionally obscure it.
<mru> with a little effort, it's often possible to find out what it is
<mru> asking the vendor can work

<cardboard64> how can I diagnose u-boot problems without UART and display? my uart seems to be multiplexed with the MMC, and I can only boot from MMC
<mru> buy a less screwed-up device
<fALSO> lol
<mru> generally, if two interfaces you require share the same pins, it's the wrong device for your needs
reinforce has quit [Quit: Leaving.]
vagrantc has joined #linux-sunxi
<mru> over here, one of the top rules is "there shall be a debug uart with dedicated pins"

<R0b0t1> yeah I've lost so much time on devices if one doesn't work more or less out of the box I buy a new one

<mace> evening folks. i've just ripped the flash from a f1c200s, and am trying to figure out what OS it's running etc
<mace> i realise the wiki says you don't support the f series, but was hoping the flash image format might be common
<fALSO> awsome
<fALSO> binwalk it
<mace> have done
<fALSO> hehe NICE; that was my only idea hehe :)
<mace> no uboot etc, a good few gzipped files, but otherwise bit thin on info
abelvesa has joined #linux-sunxi

aep has joined #linux-sunxi
<aep> any idea if you can change the i2c1 pins on h2+ ?
<aep> there's a pinctrl-0, but not sure if its valid to change those
<R0b0t1> soo you'd need to refer to the datasheet and see which pins are assignable
reinforce has quit [Quit: Leaving.]
<aep> yeah its not saying much about muxes
<aep> changing pinctrl-0 did nothing so i'm assuming the answer is no
