这次我每个空格都对过了，发现我的配置 这个不对，我的是ttyS1 pinctrl-1，应该都改成0 pinctrl-0
ttyS1，数据发送正常了
但是cat中断显示还是不对,不显示名称

正常。
# echo uart-test > /dev/ttyS1
# echo uart-test > /dev/ttyS2这样之后 cat /proc/interrupts 看串口中断次数有无增加。
您好，我试了下，发现ttyS0下面两个中断有增加，但是为什么没显示名字呀，难道配置还有问题？

ttys0作为串口控制台，使用正常，应用程序调用ttyS0也正常， ttyS1\ttyS2应用程序打开正常，发数据没反应
下面是直接通过控制台发数据的测试，
ttyS1\ttyS2，接上CH340插上电脑，发送数据以后没任何反应，收不到任何数据，但是不报错，
ttyS0控制台发送数据以后，可以直接看到数据，发送成功！
ttyS3因为不存在，直接打开错误， ttyS1\ttyS2没报错，说明DTS配置没问题。
倒腾了一天没找到问题，希望各位大神不吝赐教，万分感谢！

楼主能不能分享一下内核裁剪经验,我怎么裁减zImage都有3M,你的才2.3M,厉害
厚脸皮求上传个.config最好
我的配置文件已经开源了哦，看帖不认真 哈哈，上面有个压缩包，里面镜像和配置文件都有，改了XZ压缩方式，还可以缩到1.7M
奇怪，昨天明明放上去的呀，咋不见了，我再发一次

超级萌新 说：
还是我前面那个回复，
可以把根文件系统改小一点，比如5M，
这样扫描区域就没辣么大，可以节省一点点时间。还有，lvgl应用放 /etc/init.d/S90app 里面，记得加后台运行符号。
好的谢谢，根文件系统改小我试过哦，我把根文件系统改成了5M，对比了下发现不明显哦，时间没有明显提升。lvgl应用我没加后台符号，不过我不执行lvgl开机时间也要那么长，加了lvgl demo程序加载大概需要2S时间。
这是我改的，测试发现开机时间一模一样，没啥变化

F1C100S/F1C200S-开机时间、uboot、内核、根文件系统裁减优化问题
16M spiflash 系统
uboot裁减到122K 内核2.3M rootfs 2M 移植加入tslib，使用jffs2文件系统。我目前优化办法就是各种裁减，然后内核速度改到了800Mhz，SPI速度改到了108M。
uboot等待时间改成0S，uboot启动到内核需要3S ，内核和文件系统启动需要9S ，加起来上电启动到littlegl demo 需要 12S！
12S这个时间还是太长，请问各位大神，还有什么办法可以加快开机速度，请各位不吝赐教谢谢！

结贴啦，问题终于解决了，就是电阻触摸屏，必须用tslib处理过的数据。晚点把附件传上来。
cmake报错问题 -- 解决办法如下： 加入编译好的tslib动态链接库 libts.so
修改CMakelist.txt
从tslib读取触摸数据--测试视频如下

晕哥 说：
你的应用程序读取触摸屏数据是不是使用 tslib ?
#
#
我程序读取触摸使用的是荔枝派官方给出的代码，具体如下
#
目前怀疑触摸数据读的是原始数据，没有经过tslib校准。
#
现在正在根据这个大神的帖子 笔记-编译LittlevGL GUI demo支持tslib 来加入tslib支持，目前卡在找不到tslib.h头文件这里，编译报错！
#
正在想办法把tslib动态链接库引入到cmake里面编译！还在奋斗中

晕哥 说：
感谢晕哥的热心解答！
不过我不是这个问题、
我的 tslib 配置运行是好的，运行 ts_calibrate校准以后 ts_test触摸和划线都是没问题的，触摸很精准。
我的问题是ts_test 测试触摸精准，但是运行荔枝派nano官方littlevgl_demo_with_wallpaper程序触摸不准，我试了自己编译出来的Littlegl程序运行也是一样，只有一小块触摸区域有反应，并且位置不准确！目前手里测试的是ns2009驱动的电阻屏，驱动是从zero那里扣过来的。
我的TS LIB 环境变量配置如下，在系统任何位置输入ts_ 然后tab都可以找到命令运行！
