Linux_Bot: could you answer to the issue directly from github ? don't compute... why do you use linux-rockchip-3.0-radxa-rock.bb if you use the mainline branch.... ?

rperier: can julien join here? I'm curious if he is doing something for mainline...
<rperier>
He did a lot for "master" and for the base rules of the bsp meta layer. Frankly, these days he is not really active on "mainline"
<Linux_Bot>
rperier: i am using mainline only. but at last, i am getting error initrd.img missing
<rperier>
Linux_Bot: linux-rockchip-3.0.inc is only used by the old kernel
<rperier>
not by linux-next
<naobsd>
rperier: thanks. recently he updated radxa's wiki about mainline Linux kernel, so I guessed...
<rperier>
however, he contributes to the mainline kernel sometimes
<rperier>
(he is mostly active on the devicetree for rk3188 and rk3066)
<hipboi>
rperier, i just send the email to the list about donation for rock pro
<hipboi>
naobsd, i can ask if julien will join here
<rperier>
hipboi: wow, thanks you Tom. Really appreciated, really :)
<hipboi>
julien visited our office once
<rperier>
oh really ? do you know Julien ? nice
<hipboi>
rperier, it's our advertising ;)
<Linux_Bot>
rperier : i think error is on rockchip-update-img.bbclass. mainline also using this
<naobsd>
hipboi: no strong request. only if he can
<rperier>
I only know Julien through internet (he is french like me so communication is easy)
<hipboi>
julien's wife is Chinese, he has his holiday in China every year
<rperier>
Linux_Bot: in fact, rockchip-update-img.bbclass is used when you add "rockchip-update-img" to IMAGE_FSTYPES in your machine configuration (it is located under conf/machine/include/rockchip.inc, something like that)
<rperier>
so yes mainline uses it
<rperier>
as a workaround, you can remove "rockchip-update-img" from IMAGE_FSTYPES. and call mkbootimg my hand to create your boot.img, just to be sure that you can boot your board with what you built. (it is a workaround since I should patch and fix this class to work properly with mainline)
<Linux_Bot>
rperier: error is in this line -> mkbootimg --kernel ${KERNEL_IMG} --ramdisk ${INITRD_IMG} -o ${BOOT_IMG}, bcoz in mainline we are not generating initrd.img
<Linux_Bot>
ok
<rperier>
yes
<rperier>
because we don't want to depend on a prioprietary bootloader for this
<rperier>
the linux kernel can deal with initramfs itself , you can build an initramfs into the kernel image directly.
<naobsd>
we can pack/unpack kernel, initramfs, and dtb easily
<rperier>
Linux_Bot: yocto is designed for that purpose... you can build your initramfs with yocto directly...
<rperier>
see INITRAMFS_IMAGE variable in documentation
<naobsd>
there is no "initramfs for rockchip", you can use any initramfs for arm
<rperier>
it does not make sense to use a binary initramfs with yocto

mainline supports -> nand on rockchip ?
<Linux_Bot>
ok.. got it
<rperier>
no, it is proprietary
<rperier>
you can use almost all booting options with mainline (sdcard, usb, network...)
<rperier>
but you cannot boot from NAND
Tony_ has quit [Quit: Leaving]
<rperier>
also the NAND driver is buggy in linux 3.0... (I get random panic and freezes here)
<naobsd>
just forgot about NAND, then all problem will be gone! ;)
<rperier>
I agree
<Linux_Bot>
ok.. can we at least use NAND for storage purpose?
<naobsd>
Linux_Bot: bootloader can use NAND, but mainline kernel cannot

guys, the last time I tried to use the mainline kernel, it was not able to set the eth MAC address by taking it from the parameter file... do you know if this has been fixed or if there's a way to set it in the DTS?

gb_master: mac is an arc_emac variant and phy is a smsc lan8xxx something
naobsd has joined #linux-rockchip
<gb_master>
so, in the kernel which module is used?
<gb_master>
(I'm actually trying to understand why the virtual MAC for the ethernet module is not merged in the mainline code)
RayFlower_ has quit [Read error: Connection reset by peer]
<gb_master>
does that code read the MAC address specified in the parameter file?
<mmind00_>
gb_master: nope and never will
<gb_master>
I was trying to understand why it never will
<mmind00_>
because that parameter thingy is a rockchip-specific invention ... I think the generic way to do this is to have the bootloader replace the mac-adress property in the devicetree ... which of course doesn't work with the workaround of the devicetree appended to the kernel image
<gb_master>
oh ok... so uboot would solve the issue?
<mmind00_>
in theory ... it is supposed to solve it, but I don't think the old rk3188 uboot source do this
<gb_master>
ok, so the alternative is to modify the dts file in order to hardcode the mac address, isn't it?
<smolnij>
Hello. Is it for developers only, or I can ask dumb questions?

<gb_master>
the MAC trick worked :) but I'm actually unable to communicate with the board, as the SSH connection is dropped after entering the password and web server (running on the rr) is unreachable (mainline kernel)
<gb_master>
(even if I can actually see on my router that the RR got a valid IP address)
