求助,v3s-zero有人调试过1024x768分辨率的屏幕没有?

5寸的800x480的屏,可以正常显示。
手上有一个lvds接口的15寸1024x768分辨率的屏,买开发板时买了个rgb2lvds的小板,就测试下接大屏的效果。

按照官网指示:http://zero.lichee.pro/%E9%A9%B1%E5%8A%A8/RGB_LCD.html
重新编译u-boot,启动log如下:

明显正常显示的有800x480设置log

问题应该是u-boot里没设置对?
该如何设置啊?

官网里说的:

(时钟太高>60M貌似会hang?)
这里有个小脚本可以把fex文件的时序转换成uboot的时序:
.
.
.

这个是什么意思啊?新手没搞过,没看懂。
这个脚本要放在那里?在哪里执行?

能启动下去的,直到启动完根文件系统都正常。log我没贴全,这里贴个完整的。

Re: 求助,v3s-zero有人调试过1024x768分辨率的屏幕没有?

u-boot .config 配置文件里面有一行关于 lcd 配置的, 你修改了吗?改成了什么样子?

Re: 求助,v3s-zero有人调试过1024x768分辨率的屏幕没有?

没有改哦,要怎么改?

只是按官网的方法,将LicheePi_Zero_800x480LCD_defconfig文件复制一份,改名字为LicheePi_Zero_1024x768LCD_defconfig
然后修改
CONFIG_VIDEO_LCD_MODE=”x:800,y:480,depth:18,pclk_khz:33000,le:87,ri:40,up:31,lo:13,hs:1,vs:1,sync:3,vmode:0”

CONFIG_VIDEO_LCD_MODE=”x:1024,y:768,depth:24,pclk_khz:32000,le:198,ri:120,up:21,lo:821,hs:2,vs:2,sync:3,vmode:0”

加载这个文件后就编译了

打开.config文件,搜索了一下lcd字样,找到下面的 内容:

看不懂,好像是没有设置?

Re: 求助,v3s-zero有人调试过1024x768分辨率的屏幕没有?

为什么    CONFIG_VIDEO_LCD_MODE  是空的呢?
LicheePi_Zero_1024x768LCD_defconfig文件的内容有加的啊!

CONFIG_ARM=y
CONFIG_ARCH_SUNXI=y
# CONFIG_ARMV7_NONSEC is not set
CONFIG_MACH_SUN8I_V3S=y
CONFIG_DRAM_CLK=360
CONFIG_DRAM_ZQ=14779
CONFIG_VIDEO_LCD_MODE=”x:1024,y:768,depth:24,pclk_khz:32000,le:198,ri:120,up:21,lo:821,hs:2,vs:2,sync:3,vmode:0”

CONFIG_CMD_MEMINFO=y
# CONFIG_CMD_FLASH is not set
# CONFIG_CMD_FPGA is not set
# CONFIG_NETDEVICES is not set
CONFIG_OF_LIBFDT_OVERLAY=y

先直接修改.config编译下看。

现在启动log有看到设置了:

Setting up a 1024x768 lcd console (overscan 0x0)
dotclock: 32000kHz = 32000kHz: (1 * 3MHz * 64) / 6

但是又来了新的 问题,屏幕显示的是彩条。。。
屏接口的单8接口的。
zero的40P排线接到转接板正面的接口无显示(官网说单8接口屏接正面?)

                排线接到转接板底面的接口显示不对。一团乱

屏背光用一个其他板子点亮。
屏到小板的线与定义,我核对了一下,插在正面的话N和P是反了的,要插到底面,按照那个丝印才是 对的。

我拍了照,不知道怎么上图。。。。汗。。。

c9这个100n的电容脱了,这个滤波没有不影响吧。
R1,R2没有焊接,RFC脚是悬空的,看手册这个脚是设置上或下降沿读数据的。

我用nano点过这种分辨率的。时钟要提高才行,你可以算一下,差不多60MHZ。注意PLL也要相应调高,否则跑不起来

Re: 求助,v3s-zero有人调试过1024x768分辨率的屏幕没有?

借贴问一下,关于 RGB 接口,转 VGA 是否需要转换芯片,需要驱动么?

找到licheepi 的转换器, 看到上面好像没有转换芯片
转换器

edit: 文档芯片里找到 7123 这个芯片,应该就是了。所以问题变成驱动问题。

update: 转换芯片可透明转换,也可接受省电引脚控制,不需要特殊驱动。

长x宽x60hz就是pclk的频率,这里长宽是包含了空白区的总长。

pclk和pll设置见这个帖子

是nano的,但方式是一样的
