“插电，开机电流轻松跑上去，问题解决”
哈哈，看到这句似曾相识，楼主是不是看维修厮的视频了

没错，老维修厮了，hhhhhhh

最近在调试kmakise大佬画的黑猫F1C200s板时发现lcd的红色与绿色io口互换了，导致u-boot显示logo色彩出现错误
nono_swap
经过多番查证，发现了这么一个寄存器

7.2.5.7. TCON0_CTL_REG (Default Value: 0x00000000)
Offset: 0x040
Register Name: TCON0_CTL_REG
R/W Default/Hex Description
31 R/W 0 TCON0_En
0: disable
1: enable
Note: It executes at the beginning of the first blank line of TCON0 timing.
30:29 / / /
28 R/W 0 TCON0_Work_Mode
0: normal
1: dynamic freq
27:26 / / /
25:24 R/W 0 TCON0_IF
00: HV(Sync+DE)
01: 8080 I/F
1x:reserved
23 R/W 0 TCON0_RB_Swap
0: default
1: swap RED and BLUE data at FIFO1
22 / / 21 R/W 0 20 / 19:9 / 8:4

在u-boot中通过内存操作命令验证：

查找uboot源码，发现了lcd初始化部分的内存操作代码，按照格式写测试代码

想入手X3，看了下主线，居然连dts都没有······

超级萌新 说：

bsp的uboot貌似不显示，从hdmi显示可以看下 sys_config.fex里面的注释。

目前bsp内核已经可以正常显示,u-boot还没有解决(有数据手册,但不知道具体参数如何填写),但我不知道如何将这部分配置转移到主线u-boot 参数和主线内核设备树当中去

目前可以使用Cubieboard的镜像点亮lcd屏(修改fex文件),但主线内核无法工作(不会写设备树驱动)
不知道各位大佬能不能帮忙看一下
