<div class=""0本章主要介绍 飞凌OKA40i-C / OKT3-C 开发板 (https://www.forlinx.com/product/a40i-58.html)开机自启动应用与LCD屏幕配置的方法,其它平台请参考使用。 两款板卡均采用国产芯片设计研发,OKT3-C开发板基于全志四核车载导航处理器设计开发,OKA40i-C开发板基于全志 四核工业级处理器设计开发。 一、开机自启动方法 开机自启动脚本为/autorun.sh,可以将开机需要进行设置的命令可以在此脚本中加入。假设开机时自动执行/root/loop.sh,在/autorun.sh中加入: source /root/loop.sh & 关闭开机启动qt程序。 修改/etc/init.d/rcS 注释掉runqt。 二、 LCD配置简介 针对A40i配置 RGB24 1024x600屏幕配置文件: tools/pack/chips/sun8iw11p1/configs/OKA40i_C/sys_config1024x600.fex LVDS 1280x800屏幕配置文件: tools/pack/chips/sun8iw11p1/configs/OKA40i_C/sys_config1280x800.fex MIPI1024x600屏幕配置文件: tools/pack/chips/sun8iw11p1/configs/OKA40i_C/sys_config1024x600mipi.fex RGB24 800x480屏幕配置文件: tools/pack/chips/sun8iw11p1/configs/OKA40i_C/sys_config800x480.fex hdmi独立显示 屏幕参数: tools/pack/chips/sun8iw11p1/configs/OKA40i_C/sys_config1080p.fex Ø 针对T3配置 RGB24 1024x600屏幕配置文件: tools/pack/chips/sun8iw11p1/configs/ OKT3_C/sys_config1024x600.fex LVDS 1280x800屏幕配置文件: tools/pack/chips/sun8iw11p1/configs/ OKT3_C/sys_config1280x800.fex MIPI1024x600屏幕配置文件: tools/pack/chips/sun8iw11p1/configs/ OKT3_C/sys_config1024x600mipi.fex RGB24 800x480屏幕配置文件: tools/pack/chips/sun8iw11p1/configs/ OKT3_C/sys_config800x480.fex hdmi独立显示 屏幕参数: tools/pack/chips/sun8iw11p1/configs/ OKT3_C/sys_config1080p.fex Ø 屏幕配置lcd0小节 [lcd0] lcd_used = 1 lcd_driver_name = "default_lcd" lcd_backlight = 255 lcd_if = 0 lcd_x = 1024 lcd_y = 600 lcd_width = lcd_height = lcd_dclk_freq = 51 lcd_pwm_used = 1 lcd_pwm_ch = 0 lcd_pwm_freq = 50000 lcd_pwm_pol = 0 lcd_pwm_max_limit = 255 lcd_hbp = 320 lcd_ht = 1505 lcd_hspw = 1 lcd_vbp = 35 lcd_vt = 648 lcd_vspw = 1 lcd_lvds_if = 0 lcd_lvds_colordepth = 0 lcd_lvds_mode = 0 lcd_frm = 0 lcd_hv_clk_phase = 0 lcd_hv_sync_polarity= 0 lcd_gamma_en = 0 lcd_bright_curve_en = 0 lcd_cmap_en = 0 deu_mode = 0 lcdgamma4iep = 22 smart_color = 90 |
