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:0â€
CONFIG_VIDEO_LCD_PANEL_LVDS=y CONFIG_VIDEO_LCD_POWER=“PH12†
CONFIG_VIDEO_LCD_BL_EN=“PH8†CONFIG_VIDEO_LCD_BL_PWM=“PB2â€

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 **

Kernel image @ 0x48000000 [ 0x000000 - 0x559078 ]

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
