Stefan aka a1d3s Posted October 5, 2015 Posted October 5, 2015 Hi Igor can you provide your u-boot config for BananaPro? if i add CONFIG_VIDEO_LCD_BL_PWM_ACTIVE_LOW=n CONFIG_VIDEO_LCD_MODE=“x:1024,y:600,depth:24,pclk_khz:55000,le:100,ri:170,up:10,lo:15,hs:50,vs:10,sync:3,vmode:0†CONFIG_VIDEO_LCD_PANEL_LVDS=y CONFIG_VIDEO_LCD_POWER=“PH12†CONFIG_VIDEO_LCD_BL_EN=“PH8†CONFIG_VIDEO_LCD_BL_PWM=“PB2†Banana didnt start right. These settings needed at startup to add the 7" at boot after rebuild u-boot , screen stay black and kernel doesnt start Found U-Boot script /boot/boot.scr 1801 bytes read in 207 ms (7.8 KiB/s) ## Executing script at 43100000 ** File not found /boot/.next ** ** Unrecognized filesystem type ** 50500 bytes read in 480 ms (102.5 KiB/s) 5607544 bytes read in 517 ms (10.3 MiB/s) Kernel image @ 0x48000000 [ 0x000000 - 0x559078 ] Starting kernel ... thats all :/
Igor Posted October 5, 2015 Posted October 5, 2015 I am using default settings. No special tweaks for Banana, only general since I use mainline u-boot: https://github.com/igorpecovnik/lib/blob/second/common.sh#L28 You got it working under 4.x yet?
Stefan aka a1d3s Posted October 5, 2015 Author Posted October 5, 2015 my images under piptojects.net runs with 4.* kernel and work with touch . vga output at boot, the line above needed in u-boot because these only for 7" CONFIG_VIDEO_LCD_MODE=“x:1024,y:600,depth:24 if someone use smaller like 3,5" or 5" x and y must be changed at lemaker i discribe with bruce how to change the dts file and xorg.conf for that
