3.17 kernel from mmind git repo

[Toby Wintermute]

Hi,

I wondered if anyone has had success using the https://github.com/mmind/linux-rockchip/tree/devel/workbench kernel on the Radxa?

If so, care to share any hints or tips?

thanks,

Toby

[Tom Cubie]

You can refer this to build the kernel

http://wiki.radxa.com/Rock/Linux_Mainline

more info about the mainline kernel(status, what's working/not
working) are welcomed to be added.

Thanks Tom.
The part I was missing was:
cat arch/arm/boot/zImage arch/arm/boot/dts/rk3188-radxarock.dtb > kernel.img

I can boot the 3.17-rc1+ kernel from mmind's tree, which I hear is a
bit further ahead than the mainline kernel.. but it's still no-go on
the NAND, so booting beyond initramfs is not possible.

:(

there are sdmmc, usb, ethernet. you can develop further :)

[Toby Corkindale]

Cheers! iPXE booting would be neat.
Do you have any hints for getting an initrd going that contains enough
to bootstrap from it?

Do you think NAND support for the Radxa will ever occur on a mainline kernel?

I'm using my own initramfs (based on http://androtab.info/miniroot/).
but there is no restriction, please use/make any initramfs.

it's matter of Rockchip. Rockchip contributes mainline a lot (for
RK3288), but I don't expect so much.

[Toby Corkindale]

For these mainline kernels, is the initramfs coming from the
CONFIG_SOURCE_INITRAMFS archive during the kernel build, or from the
--ramdisk parameter of mkbootimg?

I tried only CONFIG_SOURCE_INITRAMFS for now. you may try another method.

Having a known-good kernel config would be a big help. At the moment I

mmind's devel/workbench is updated very frequently, it may work, or it
may not work. and generally "current status" includes patches floating
around.

I'll try to prepare working snapshot...

[Toby Wintermute]

Hi Naoki,

I just wondered if you'd had time to prepare a known-good kernel config and kernel source snapshot?

Maybe just something as simple as cloning a repo (mmind or other?) on Github, making a tag like "this-works" on a point you know works, and committing your own kernel config as-is?

I've tried to get somewhere myself a few times, but so many combinations of kernel options result in either no hardware (sd, network) working, or the board crashing out straight away.

I tried some
https://github.com/naobsd/linux/branches/all
but not finished yet. you may try my snapshots, but please don't think
everything is perfect.

existing snapshots branch will not be updated, it's only for temporary
testing. I'll try to make newer snapshot(s) if possible (until
mainline have all necessary patches).

getting "time" is most difficult task for me... ;)

Thanks, I'll give these a try. Appreciate you taking the time.

For for anyone else out there, here's some instructions to get a
bootable system using SD card as root filesystem.
Get the rockchip/snapshot-20140928 branch from Naoki's github.

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
make rk30_rk31_defconfig
make menuconfig
--> navigate to General Support, and DESELECT the initramfs support.
--> exit config, saving as you go.
make -j6 zImage modules
cat arch/arm/boot/zImage arch/arm/boot/dts/rk3188-radxarock-full.dtb
> /tmp/kernel.img
mkbootimg --kernel /tmp/kernel.img --ramdisk /dev/null \
--cmdline "console=ttyFIQ0 console=tty0 root=/dev/mmcblk0p1
rootfstype=ext4 init=/sbin/init" \
-o /tmp/boot.img

Then use rkflashkit to flash boot.img onto your boot partition of the
Radxa NAND.

If you want a boot.img I've prepared earlier, so you can skip all
that, just grab:
http://vps.dryft.net/radxa/tjc_boot_v1.img


You then need to get yourself a root filesystem (I used the linaro
server base) and add the built kernel modules (from above) to it.
You'll also want to configure something into /etc/hostname and add the
following to /etc/fstab:

/dev/mmcblk0p1 / ext4 rw,relatime 0 1
none /tmp tmpfs defaults 0 0
none /var/tmp tmpfs defaults 0 0

Don't forget to configure the network if you want to use that.


As it stands, I have a booted, networked Radxa running 3.17-rc6+
kernel on Ubuntu/Linaro 14.04 now.
I'm happy :)

Thanks to Naoki for doing all the hard work to assemble a working
kernel snapshot.

-Toby

Hi,

console tty name is ttyS2 on mainline, you may need to prepare
/etc/init/ttyS2.conf. (it depends on distro/rootfs configuration)

(I'm sorry, I cannot prepare newer tree yet...)

Dear Toby Wintermute,

nice to see you are successful on getting a recent kernel to work on radxa.

Are you using a rockchip pro?

I have some trouble to boot a 3.17. kernel on my rockchip pro. I am a
little bit confused about the partitions on the sd-card, how to generate
them and what to put in the parameter file.
You told in the radxa community that you put a complete set of stuff (kernel, paramater, image) online. Unfortunately this package is not available at the
moment.
I would like to have a look on a working sdcard partition and a working parameter file to go on with this rockchip pro.

Perhaps you can put again some light on it!?

Thank you for your effort,

regads, lumax!

I don't think so? I have a Radxa Rock board.

Ah, I entered the wrong URL on the google groups post. Sorry.
It should be:
http://vps.dryft.net/radxa/radxa_boot_bits.7z
It includes:
kernel.img (zimage + devicetree)
boot.img (kernel.img plus a null initrd via mkbootimg)
parameter-linux.img (parameter-linux created via rkcrc -p)
rootfs.img (ext4 filesystem for sdcard)

To boot, I flash the boot.img from there to the boot partition on the
Radxa NAND, and then I take an sdcard, with one partition filling the
card, and dd rootfs.img to it. That works for me.

I tried making an actual all-in-one SDcard image, but I couldn't get
it to work by following Naoki's info here:
http://androtab.info/radxa_rock/sdboot/
But when I tried booting, I just received error messages on the Radxa.
I wasn't sure how I was supposed to be making partitions on the sdcard.

did you make a partition and make root file systen on it?

if you used whole disk (not a partition) to make root file system, you
have to specify mmcblk0 instead of mmcblk0pX.

You are right!
Using a proper partition table makes the kernel boot the rootfs!

I wonder if the kernel is able to drive HDMI?
This first attemps doesn´t work for HDMI.

@Tobi
You have a Ubuntu/Linaro X system running with HDMI output on the
3.17 kernel ?

Cheers, lumax.
