hello!
<zzarr>
I need some help getting started with initramfs
<zzarr>
I have a chroot running on an arm architecture (binfmt from x86_64)
<zzarr>
I have installed mkinitramfs in it
<zzarr>
I wish to make a initramfs for kernel 4.4 with my config (I have the source/config in a folder)
<zzarr>
I can compile the kernel no problem
<zzarr>
I have Ubuntu 16.04 both arm and x86_64
<stdint>
zzarr, usually you don't need it
<stdint>
you could boot any system you want without initramfs
<stdint>
and the other usage of buildroot is making initramfs for testing
<stdint>
the Ubuntu/Debian made initramfs really useless, just for loading modules
<zzarr>
okey
<zzarr>
so I could make a boot image without a initramfs?
<zzarr>
I see... mkbootimg only needs a kernel
<zzarr>
stdint, do I need to write any special commandline for the kernel?
<stdint>
not
<stdint>
just set the rootfs in bootargs
<stdint>
and included those target driver(like eMMC, nand or SDMMC)
<stdint>
zzarr, you may need to read some book about the linux and linux kernel basic
<stdint>
LDD3 would be a good start
<zzarr>
okey
<stdint>
my teacher GNUtoo also read this book carefully when I start in this area
<stdint>
let me read this book, I meant
<zzarr>
I thought the [ --cmdline <kernel-commandline> ] option to mkbootimg was the bootargs
<stdint>
I am not familiar with mkbootimg
<zzarr>
I have done this before, just need to remember/reunderstand
<zzarr>
okey
<stdint>
but I am talking about the bootargs that the u-boot send to kernel
<zzarr>
I know
<zzarr>
I thought perhaps they are the same, I'll need to read up on it
<zzarr>
arent the bootargs from u-boot the argument which is provided to the kernel during boot?
dlezcano has joined #linux-rockchip
<stdint>
yes
<zzarr>
nice
<stdint>
I would rather said it is provides before the kernel is boot
<zzarr>
true
<zzarr>
but the kernel knows about them :)

<zzarr>
stdint, are you sure the parameter is called rootfs or is it root?
<stdint>
in kernel parameter, it is "root="
<stdint>
but the partition used as value for it, the context of it would be called the rootfs
<stdint>
that is why I suggest you have better read the LDD3
<stdint>
after you read it, most of problems would go
<zzarr>
okey, I have it open as a pdf now

mmind00: hey, it was my wedding this week-end. BUT, I am on vacations until Thursday. It's plan, this is the first thing that I will do today or tomorrow :)
<rperier>
naobsd: PX3/5, what is the SoC ? I don't have this board, so it's not yet supported in meta-rockchip. That's not complicated to add a new board
<rperier>
naobsd: so you can add it and send me a patch :)
<mmind00>
rperier: hehe, no problem and congrats :-) ... just take your time
<rperier>
what do you think ?
<rperier>
mmind00: thanks !
<rperier>
;)
<mmind00>
rperier: px3 is an automotive rk3188, px5 same based on the rk3368
<rperier>
I think that both should work just fine (modulo bugs)
<mmind00>
rperier: especially the px3 is nice to see, as I'm still hoping that someone will do grapics support for it, now that we're seeing upstream patches for them already
<rperier>
yeah it would be nice for rk3188, however that's not the most trivial part in the kernel (graphics support).
<mmind00>
rperier: yep ... that why it is nice to see Rockchip people sending px3 dts patches :-)
<rperier>
yep :)
<rperier>
indeed

karlp: my linux-rockchip on git.kernel.org is strictly for that mainline work ... and while I also have a github counterpart with some devel/foo branches that do throw together some more upstream patches, these are mainly for my testing and not meant for people to base their work upon
<vagrantc>
mmind00: did you ever find enough confidence to merge that veyron-speedy.dts one-liner? is there anything more I can do to move that forward?
<mmind00>
vagrantc: rperier wanted to provide a second opinion from his speedy ... but as you can see in the backlog from today, he had other commitments this weekend ;-)
<vagrantc>
ok
<mmind00>
vagrantc: but it looks like he has this on his todo list for the next days
<vagrantc>
yay
* vagrantc
is hoping it (or some better fix) will hit mainline linux in time for Debian's freeze in a few months
<mmind00>
vagrantc: Debian plans on using 4.9, right?
<vagrantc>
it was a while back, but i think it was going to try for 4.11, based on estimates of timing and so on
<vagrantc>
though smallish backports like that are usually fine, as long as it's in mainline (and to a lesser extent, next)
<naobsd>
karlp: for kernel, just set ttyS2 speed. for spl/trust binaries, I have no idea.
<naobsd>
(btw the repo/branch I used is not rockchip-linux's. only geekbox's was available at that time, it has exactly same commit id in manifest in stock rom

naobsd: was actually just _starting_ hadn't even built a kernel yet, was just hooking up a serial to the pin header, couldnt' find the right baud.
<karlp>
but thanks, your notes will work well for me I think.
<karlp>
mmind00: fair enough, Iguess these days enough is in mainline, I can then maybe pick in patches myself I guess.
premoboss has quit [Ping timeout: 265 seconds]
<karlp>
whee, 1500000 was what I was missing
<karlp>
that and the cp210x customization utiltity to alias it to be useful baud
<karlp>
mine has: U-Boot 2014.10-RK322X-10-g993d334 (Mar 15 2016 - 15:24:04) so far
<naobsd>
it's in "product" branch on rockchip-linux u-boot repo
<karlp>
you had an mxq4k too right?
<naobsd>
I assume we can use product branch safely :)
<naobsd>
mxq4k yes
<karlp>
I'm not really interested in replacing uboot unless I need to, ws just looking at a regular mainline kernel and a linux root FS. what branch have you last used on this board?
<naobsd>
Hotack T066-V1 board
<naobsd>
well
<naobsd>
I tried it several month ago, I didn't use recently
<naobsd>
at that time I tried dts for rk3228 in linux-next
<naobsd>
now rk3229 should be available...
<naobsd>
checking
<karlp>
yeah, I'd just seen some rk3229 patches go past, thought it might be worth a try
<naobsd>
I guess there is no difference between rk3228 and rk3229 support _in linux kernel_
<naobsd>
yet.
<naobsd>
but it seems there is small difference in rk3228-evb.dts/rk3229-evb.dts ;)
<karlp>
am I right in reading your logs, that I should just be able to make a rk31xx style sdcard and use upgrade tool to flash the kernel?
<karlp>
there's still no nand support, that'sfine, I'll be fine with an sdcard, ethernet and usb
<naobsd>
well, if you use SD kernel, upgrade_tool is not required. upgrade_tool is for on board flash
<karlp>
oh, yeah, I guess.
<karlp>
upgradetool can give me nand kernel, but would always need rootfs on either sd or emmc (and there's no emmc on this board)
<naobsd>
(it can be used for SD if it boots from SD)
<karlp>
rk3229-evb dts has ethernet but no usb it seems?
<karlp>
did you ever get that working?
<naobsd>
when what you need is partitioned/mkfs-ed SD card
<naobsd>
I cannot remember detail
<karlp>
no problem, thanks for the pointers so far already :)
