===H3 Linux-3.4 BSP配置CVBS输出===

[[CVBS/zh|查看中文]]
对于H3 Linux-3.4系统映像,NanoPi M1 Plus / NanoPi M1 / NanoPi Duo2 支持配置为CVBS输出。由于HDMI / CVBS只能选择一路显示输出,而HDMI输出更通用一些,所以M1 Plus / M1默认是使能HDMI禁止CVBS,而Duo2由于没有HDMI接口,所有默认是使能CVBS。
+
  
参考下列操作可以自行手动为M1 Plus / M1使能CVBS输出。

1.1 Linux-3.4

FriendlyElec's image for H3 Linux-3.4 works with the NanoPi M1 Plus / NanoPi M1 / NanoPi Duo2 and it supports CVBS output. This image supports either HDMI or CVBS output. For the NanoPi M1 Plus/M1 by default HDMI is enabled and CVBS is disabled. For the NanoPi Duo2 by default CVBS is enabled and HDMI is disabled.

Refer to the following steps to manually enable CVBS for The NanoPi M1 Plus / M1.

1.1.1 Reference

$ git clone https://github.com/friendlyarm/h3_lichee.git lichee --depth 1
$ ls lichee/doc/H3 sys_config.fex使用配置说明V1.1.pdf。

1.1.2 Edit sys_config

Let's take the NanoPi M1 Plus as an example to show how to edit the sys_config file. This applies to the NanoPi M1 too.
The sys_config file is in the directory shown as follows:

$ ls lichee/tools/pack/chips/sun8iw7p1/configs/nanopi-h3/board/sys_config_nanopi-m1-plus.fex

Disable HDMI and enable CVBS:

[disp_init]
disp_init_enable = 1
disp_mode = 1
screen0_output_type = 3
screen0_output_mode = 5
screen1_output_type = 2
screen1_output_mode = 14
fb0_format = 0
fb0_width = 0
fb0_height = 0
fb1_format = 0
fb1_width = 0
fb1_height = 0
 
[hdmi_para]
hdmi_used = 0
hdmi_power = "vcc-hdmi-18"
 
[tv_para]
tv_used = 1
tv_dac_used = 1
tv_dac_src0 = 0

1.1.3 Compile and Update

Compile lichee:

$ cd lichee/fa_tools
$ ./build.sh -b nanopi-m1-plus -p linux -t all

Update the image in an SD card with an existing image:

$ cd lichee/fa_tools
$ ./fuse.sh -d /dev/sdX -p linux -t u-boot

Note: you need to change "/dev/sdX" to the actual device name recognized in your system.
