Add DTD files for M82_1G and M82_2G boards, also known as MXIII

[steeve]

These S802 boards come in 2 flavours:

• 1G RAM, 8G NAND, RTL8188
• 2G RAM, 8G NAND, AP6210

They were extracted from the firmwares at http://www.bee-link.com/en/article.php?id=134

Thank you for your great work.

[steeve]

I should add that I've checked for doubles in case they were already there under a different name with shasum.

Hi Steeve, It seems that MXIII uses the same K200 board as the M8 box. So you can use existing Meson8_k200a_1G.dtd and Meson8_k200a_2g.dtd. They may look a liitle different from the ones that you extracted from MIII firmwares, but that's mainly because the extracted device trees don't have comments.

[steeve]

Indeed the update files has the k200 prefix, which indeed would point in that direction.

The weird thing though is that I've tried to use dtc to do a dts to dts conversion, for instance:

$ dtc -I dts meson8_k200a_1G.dtd -O dts -o tmp.dtd
$ diff tmp.dtd meson8_m82_1G.dtd

And I'm finding some significant differences, such as:

-       phys_offset = <0x200000>;
-       linux,total-memory = <0x3fe00000>;
+       phys_offset = <0x0>;
+       linux,total-memory = <0x40000000>;

I guess I should really test building the firmware and see if it boots

[codesnake]

Please try to build with meson8_k200a_1G.dtd and let me know if it works.

[steeve]

Will do, many thanks

[steeve]

Alright, I just tested it. The kernel boots, but no output to HDMI. Here is the console log: http://pastebin.com/pMDMcXCq

I've just unpacked/repacked/signed your OTA update with the new dtb.

I'm going to test the extracted dtd.

[steeve]

Weird, with the extracted dtd, the kernel doesn't boot...

But you even use different kernel from this one. You have 3.10.57 version in your log, but this has 3.10.33 version number.

[steeve]

Thanks for your quick answer Where do you see 3.10.33? I've used the same kernel/ramdisk when mkbootimg

[codesnake]

I see 3.10.57: [ 28.076615@0] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.10.57 #1

[steeve]

I'm using the kernel you provided in OpenELEC-CodeSnake-Meson8-K200-devel-320a148.zip I shouldn't ?

You on IRC maybe?

[codesnake]

No, you use different kernel from the one in this repository. I never used kernel 3.10.57 in my builds.

[steeve]

Ok I must have screwed up somewhere. Anyway, many thanks. I'll reopen the PR if need be
