Support for 1360x768@60Hz resolution/refresh rate

No, I just tell him what needs to be changed in kernel to support another resolution and it is not easy.

I'm still working on it. The problem with chaging the script bin is that he only support standard formats. So, i needed to find a way to code a new standart and index it, so using the said code could work. I used the code that i put in the file " include/video/sunxi_display2.h", and since i used the codes 0x1f and 0x20, i used the codes 31 and 32 in the bin file. Both failed. they cimply give me no output in the video. However, using the code taht was alreadly there worked when i change it back. The is any way to find out what errors are happening or debug the code? Even a simply log would be of help.

Besides, it seems that there is a diference between the version of sunxi used in this build and the one in the official sunxi repository, what makes development even harder(file names as different and in diferrent locations).

Edit: I included the pacth file that i generated, Did i missed anything?

At first glance, everything seems fine... I strongly suggest that you connect serial console and during boot you can read all the messages kernel produces and for the bonus you get console so you can examine system state. My favorite method for debug such things is to put myriad of printk's in kernel code on interesting places so I know as much as possible about the system state.

I only have a ultrabook as computer, any way i can see the serial console output usins usb ports?

And how i put those printf around the code?

I also would like to know how i use kernel arguments in this project:
http://linux-sunxi.org/Kernel_arguments

its seems like a easier way to set my desired resolution.

And how i recompile the project? "make clean" and then "make" again?

You have thousands of USB to serial adapters on ebay (I'm using FT232RL based adapter). Just be sure that yours is set to 3.3V. Just connect GND->GND, TX->RX and RX->TX. Settings are standard one, 115200 baud, no parity and 1 stop bit.

They are not printf, they are printk, but otherwise they are used exactly the same. How do you use it is up to you. Probably you would like to know if some variable has same value you predicted.

Kernel arguments can be changed by stopping U-Boot to auto run boot.scr and for that you need serial console. Another, easier, option is to change it in projects/H3/bootloader/boot.cfg but for that you have to recompile the U-Boot. Please note that you don't have disp.screen0_output_mode kernel argument. AFAIK, it was added by community and is not original from Allwinner. Because there is not much interest in Allwinner's H3 kernel apart for documentation purposes, this was not reimplemented here.

If you want to recompile the image, you execute standard command again (ARCH=... PROJECT=... ... make image). Changes should be picked automatically. But in some cases they are not - usually aforementioned boot.cfg and all fex files under projects/H3/sys_config. For that to work, you have to clean specific package first ARCH=... PROJECT=... scripts/clean <package> where <package> is u-boot for boot.cfg or linux for any fex file. After that, you execute standard make image command to rebuild the image.

Actually, it is supported, if the connection is vga, as described in here: http://linux-sunxi.org/Fex_Guide#.5Bdisp_init.5D
in hdmi, the story is all different.

Anyway, I ordered the connector finally , this one.

Got caugt up in some network problems in my house, so this why i waited that long. Anyway, ETA is 2 months, till then, don't expect any progress, sorry. Bye.

BTW, how i will use it? Any guides on that?
