gk802: Add initial support

Hello,
I would like to commit support for Zealz GK802 Freescale i.MX6 Quad Core device.
The work is based on the information from
https://github.com/imx6-dongle/wiki/wiki

Unfortunately it is not complete yet. U-Boot is working and the device will load the kernel uImage from first fat partition. With the attached "ubootcmd" file copied to the first fat partition of your micro-sd card, the kernel will start completely, but will fail to init systemd (see attached "gk802-boot.log" file).

I already tried several bootargs configuration via the ubootcmd file, up to following bootargs config without any further success:

setenv bootargs 'console=ttymxc3,115200 consoleblank=0 root=/dev/mmcblk0p2 rootfstype=ext3 init=/lib/systemd/systemd rootwait rw video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24'

I hope for the communitie's support to be able to finalize this work and get the GK802 supported within Yocto.

Regards,
Matthias

Hello Matthias,

Last time I talked with GK802 guys they were working in porting it to U-Boot mainline; I have made the patches here to integrate it to meta-fsl-arm-extra a while ago but I am awaiting for their U-Boot patch. I am attaching the three patches for reference anyway.

I think you should focus in get it booting and working, initially, with core-image-base and then move to more complex use-cases like systemd afterwards.

Please check the patches I attached to see if they help in something.

1.8.3.2

Would it be "the classic DEVTMPS" problem?

Please, check if it's enabled on your kernel
CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y

Daiane

The DEVTMPFS did it. Now it is starting including systemd ;-).

I can remember that I saw this issue within one of the forum discussions before.

I will update the patch accordingly.

Matthias

Hi Matthias,

Some time ago me and guys interested in GK802 started the imx6-dongle project - https://github.com/imx6-dongle You probably using kernel from there.
It kinda stuck right now because the wave of interest in GK802 already passed and guys with skills already done everything with it and lost interest. If you want to have access to imx6-dongle repos - I can add you, or merge your pull requests.
There a couple of things left to do - for example - port our hardware support to 4.0.0 BSP or to 3.5.7 kernel in future.

Same also can be applied to anyone who wants to work on GK802 - you are welcome.

Best Regards
Dmitriy Beykun

I added the DEVTMPFS configuration to the gk802 defconfig and fixed some issues within uboot config file gk802.h. The gk802 is now booting.

Attached the respective patch.

@Otavio: How do we proceed with the awaiting u-boot upstream for gk802?

Matthias

1.8.3.4

Ok; let's work to get it merged here in meanwhile.

I did a fast review in the attached file and I have following remarks:

- please send patches using git send-email (as it easy review);
- split the patches (u-boot, kernel, machine);
- add a defconfig file to easy user customization (pass it on
savedefconfig make target);

After rework the patch, please send the three patches to mailing list and we review them again.

Good work. :-)
