I've been running with "iomem=relaxed" kernel option, and -3 for nearly a week,
everything is fine.
So I guess we find a workaround, at least.

Another option is to use GPIO interface by /sys
But I don't have much experience for it.

Thanks for your info.
Seems better not to touch this part for now.

It looks like there's at least a devicetree for it in linux:

arch/arm/boot/dts/imx6q-gk802.dts:  model = "Zealz GK802";
arch/arm/boot/dts/imx6q-gk802.dts:  compatible = "zealz,imx6q-gk802", 
"fsl,imx6q";

Several of the drivers (hdmi, microsd, usb-otg, internal usb) are
marked as: status = "okay";

The .dtb is present in the linux 4.9.x linux-image-4.9.0-2-armmp
package. There are several other imx6 devices supported in debian's
armhf kernels, so the necessary drivers *might* already be enabled.
That all sounds reasonably promising.

So, your task will be to figure out how to get the bootloader that comes
with it (or port it to a modern u-boot) to load Debian's kernel,
initramfs and the appropriate .dtb file.

You'll probably want to figure out how to connect to the serial
console...

Installing Debian on a Zealz GK802/imx6 dongle?

[Rogério Brito]

Dear people,

Some years ago I bought a Zealz GK802 dongle (which, if I understand
correctly from what I read on the web [0], is an imx6-based
system---but I am not sure) which came with an 8GB microsd card
running Android 4.0.

My primary intention with it would be to serve me as a device to run
Kodi, but, as soon as it was doing *anything*, it overheated and
locked hard.

I left it there gathering dust, despite it being potentially able to,
while not serving as my primary intention, act as something else, like
downloading some torrents or building some packages, given that it is
much more powerful than my KuroBox Pro with (which is an armel device
with only 128MB of RAM---of course, the IO abilities of the two
devices are mightly different).

Anyway, revisiting this device, I am interested in getting any more
modern operating system on it and, of course, Debian is my first
choice. Does anybody here have any experience with this kind of system
or something similar? If yes, how have things evolved in the last 4
years? Is it too painful to install Debian on it? If nobody has any
experience with it, I am interested in investing some effort into
getting it working, so that I can make some use of this piece of
hardware that I have here.

I can provide some details with respect to the hardware and document
my experiences and the installation process somewhere for reference of
others (kind of what Martin did with some systems on his personal
page) with the ultimate goal of getting it working well with Linux.


Thanks for any help,

Rogério.

Re: Bug#861281: rnahybrid: FTBFS on armel

[Edmund Grimley Evans]

There may be no demand for this package (rnahybrid) on armel, but the
FTBFS might be caused by a bug in gcc-6, which would be worth
reporting if someone can confirm it.

The warning is about an off-by-one in the loop condition that 
writes past the end of the array - that's an unrelated bug.

There are 3 levels of loops at the location of the warning,
that is not a problem.
