Hello, Everyone

    I try the manual build my A13-OLinuXino-WIFI evaluation board with LCD+Touchscreen using mainline u-boot and linux-sunxi http://linux-sunxi.org/Linux_Kernel#Compilation but I stuck at the GPIO initial state when board is booting. It seems like the script.bin doesn't initial the GPIO as I configure in .fex file. I configure the pins as an output but it is the input at the beginning.

    I used to build the embedded linux system for BeagleBone Black and I think maybe the Device Tree things could help me. So, I switch to the mainline kernel (sunxi-next) as descript in http://linux-sunxi.org/Mainline_Kernel_Howto. The result is that I stuck with making 4.3" LCD touchscreen work with the mainline kernel. Below is the details.


u-boot menuconfig
Code Select
CONFIG_FDTFILE=sun5i-a13-olinuxino.dtb

CONFIG_VIDEO=y
CONFIG_VIDEO_HDMI=n
CONFIG_VIDEO_VGA_VIA_LCD=y
CONFIG_VIDEO_VGA_VIA_LCD_FORCE_SYNC_ACTIVE_HIGH=y

/* for LCD-OLinuXino-7TS, I used this */
CONFIG_VIDEO_LCD_MODE=x:800,y:480,depth:18,pclk_khz:33000,le:16,ri:209,up:22,lo:22,hs:30,vs:1,sync:3,vmode:0

/* for LCD-OLinuXino-4.3TS, I used this */
CONFIG_VIDEO_LCD_MODE=x:480,y:272,depth:18,pclk_khz:9000,le:10,ri:5,up:3,lo:8,hs:30,vs:5,sync:3,vmode:0

CONFIG_VIDEO_LCD_DCLK_PHASE=1

This is the boot log When I 1st boot it:

    the board was display using VGA port. So, I set some environment variable like shown below.
Code Select
sunxi> setenv video-mode sunxi:800x480-18@60,monitor=lcd
sunxi> setenv lcd-mode x:800,y:480,depth:18,pclk_khz:33000,le:16,ri:209,up:22,lo:22,hs:30,vs:1,sync:3,vmode:0
sunxi> setenv machid 102a
sunxi> setenv stderr serial,lcd
sunxi> setenv stdout serial,lcd
sunxi> saveenv
sunxi> reset

    Then, I have the boot logo (small rectangle with Tux image) shown on the 7" LCD but the vga screen still show the display, too (but some part clipped but I don't want to use it anyway). Once the booting is completed, The 7" LCD screen show the login prompt. The boot log is:

  Why it's saying "video-mode 800x480-18@60 not available, falling back to 1024x768-24@60"? and how could I disable displaying on VGA screen?


  My goal is to use OLinuXino with 4.3" LCD touchscreen. So, I try to change to LCD-OLinuXino-4.3TS.
for the u-boot menuconfig what I change is :

Code Select
CONFIG_VIDEO_LCD_MODE=x:480,y:272,depth:18,pclk_khz:9000,le:10,ri:5,up:3,lo:8,hs:30,vs:5,sync:3,vmode:0


for the environment variable is change this:
Code Select

sunxi> setenv video-mode sunxi:480x272-18@60,monitor=lcd
sunxi> setenv lcd-mode x:480,y:272,depth:18,pclk_khz:9000,le:10,ri:5,up:3,lo:8,hs:30,vs:5,sync:3,vmode:0
sunxi> setenv machid 102a
sunxi> setenv stderr serial,lcd
sunxi> setenv stdout serial,lcd
sunxi> saveenv
sunxi> reset


  The result is :

THE BOARD STUCK HERE..!!! Nothing I can do except reboot the board



  It still saying, "video-mode 480x272-18@60 not available, falling back to 1024x768-24@60. Setting up a 480x272 lcd console" but this time the board hang as in the boot log shown above. I have no idea why?

Could you please, point me some way out what I've done wrong?

Thank you in advance and sorry for my English,

Can you rapidly explain me how to make this:

Hello pawnies20,
Do you mean where to set these config?
I've followed the instruction shown in this link http://linux-sunxi.org/Mainline_U-Boot

1. checkout v2015.04
Code Select

$git clone git://git.denx.de/u-boot.git
$cd u-boot/
$git checkout v2015.04 -b tmp

2. set default config
Code Select

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- A13-OLinuXino_defconfig


3. Now, you can set those setting by issue this command
Code Select

make ARCH=arm CROSS_COMPAILE=arm-linux-gnueabihf- menuconfig


Hope this help.  :)
