@steward 感谢大佬的回答:)，触控的信息是可以读取的，现在正打算用单片机发送这些数据看看能不能正常工作@_@

@steward 啊啊啊，谢谢你的解决方法，我一直没怀疑是xboot中断设置问题，还在抓I2C信号，感谢你的解决方法，真心感谢XD

@bayche 在 Yuzuki Lizard V851S开发板 –获取正确的本地时间 中说：

@ary_ye 有一点不同
具体参考
https://forums.100ask.net/t/topic/3021
是基于docker版V851S开发环境

好的，受教了

@bayche 在 Yuzuki Lizard V851S开发板 –获取正确的本地时间 中说：

@ary_ye 你跑tina的话是没有systemd注册，ntpd是service用不了ntpdate

那大佬你用的不是Tina嘛？有啥办法解决捏？

只能重新烧录，替换BOOT分区。

如题，由于要通过ntpdate进行网络对时，但是出现了

Error resolving ntp.aliyun.com: Unrecognized service (-8)

根据小正太大佬的说法是要添加systemd，但是在下列添加systemd-timedate服务以后就编译不通过了，而且整个编译过程没有ERROR的标识，唯一感觉有问题的只有缺了这堆文件

求大佬们指点指点

大佬，出现Error resolving ntp.aliyun.com: Unrecognized service (-8)怎么解决呢？能ping通ntp.aliyun.com

找到问题了，grep一下这个宏定义，发现是在openssl库里面的，在make menuconfig里面把下面这个选项勾上就行了

用的TinaLinux，错误信息如下，请大佬们帮忙看看是哪里出了问题。

ntp_crypto.c:1613:31: error: 'RSA_PKCS1_OAEP_PADDING' undeclared (first use in this function)
      EVP_PKEY_get0_RSA(pkey), RSA_PKCS1_OAEP_PADDING) <= 0) {
                               ^~~~~~~~~~~~~~~~~~~~~~
ntp_crypto.c: In function 'crypto_alice2':
ntp_crypto.c:2516:11: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
  if ((rsa = EVP_PKEY_get0_RSA(peer->ident_pkey->pkey)) == NULL)

如题，每次修改设备树之后都需要重新打包、烧录，想问问大佬们有啥办法可以直接替换dtb的方法。

@whycan @whycan 就是这步出了问题，ls /dev以后没有V853_LED这个设备 ，我在启动输出的信息里面也没找到相关的内容。

@whycan晕哥 晕哥好，教程地址是 https://v853.docs.aw-ol.com/soft/dev_gpio/ ，里面是没有设置gpio的设备树的，刚接触不太懂，大概要怎么改呢？
