@rtqqq 未修改前，启动都正常么？
另外发一下现在的修改记录出来看看

@funiot-xyz 后来搞定了吗

终于调通了，简直就是一个大坑...由于WiFi驱动里面cfg80211.h的接口定义跟内核版本的cfg80211.h的接口不一致，导致调用时传入的数据不对了，但是奇怪的是，这编译时或者运行时为什么不报错呢......

buildroot 编译时出错:
g++: error: unrecognized command line option ‘-fcf-protection’; did you mean ‘-fstack-protector’?
是什么原因?
arm gcc: gcc 版本 12.2.1 20221205 (Arm GNU Toolchain 12.2.Rel1 (Build arm-12.24))
host gcc: gcc version 9.5.0 (Ubuntu 9.5.0-4ubuntu2)
host gcc 换成 gcc version 13.2.0 (Ubuntu 13.2.0-4ubuntu3) 也是一样的现象.

@qinlinbin 您好，想请问一下可以分享一下串口DMA的测试程序嘛，十分感谢！

@zm960406 支持，但是需要修改一下openOCD中的. cfg 配置文件

@zm960406 您好大佬，我想请教一下如果想使用串口DMA应该如何测试，可以分享一下DMA测试程序吗，感谢！

@awwwwa 老师你好，这个驱动还有个问题：中断只能响应40us以上的高电平才会执行中断，但是我的驱动里面中断函数里面是上升沿触发。我看教程是通过设备树来设置，是因为我是驱动程序里面设置，没有成功吗？还是有其他因素呢？
中断注册部分代码是：

ret = request_threaded_irq(fsfpgaindev.irq_num, irq_gpio_spi_handler,irq_gpio_spi_thread_func,IRQF_TRIGGER_RISING, "irq_gpio", &fsfpgaindev); if(0 > ret) { printk("request_irq error\r\n"); goto fail_irq; } else { printk("fsfpgain irq_num:%d\n",fsfpgaindev.irq_num); }

@yelong98 解决了吗

问题已确认，ubuntu有个modem管理，/usr/sbin/ModemManager 会去管理4G模块，grep 发现里面有 option1 的操作，赶时间简单粗暴直接删除就可以了

@godzhou0909 大佬，解决了吗？我也是这个问题

将文件打包进入 Tina Linux
Tina Linux 提供 busybox-init-base-files 作为 rootfs 的接口提供用户将文件打包进入固件的功能。busybox-init-base-files 内的文件在打包编译系统的时候会覆盖进入 rootfs 内。

文件夹的路径 openwrt/target/v853/v853-vision/busybox-init-base-files

01

配置开机自启
开机自启可以说是嵌入式 Linux 投入应用中最主要的一环。这里以自启动 lv_example 介绍一下 Tina Linux 如何配置开机自启功能

开机自启动主要的配置位于 openwrt/target/v853/v853-vision/busybox-init-base-files/etc/init.d 文件夹内。系统启动后会按顺序执行这里的脚本，可以通过编写这里的脚本实现开机自启功能。

02

编写一个 S99lvdemo 的启动脚本，S99 代表他会等待之前的 Sxx 脚本执行完毕他才会执行，这里的排序是字符的顺序。

#!/bin/sh

Start lv_example ....

start() {
printf "Start lv_example .... "
lv_examples 1
}

stop() {
printf "Stopping lv_example .... "
}

case "$1" in
start)
start
;;
stop)
stop
;;
restart|reload)
stop
start
;;
*)
echo "Usage: $0 {start|stop|restart}"
exit 1
esac

exit $?
编译、打包烧录，可以看到开机自启了 lvgl 的操作界面。

你好，请教一下，如果不使用流控，那么CTS 和RTS应该保持什么状态，悬空还是接地？会影响蓝牙功能吗？

@awwwwa 你这个也是错的，这么写会把所有通道都关掉，而不是指定的那个……

lcd的我已经屏蔽掉了，还是不行最后我直接用寄存器给上拉了！谢谢

@anruliu 请教一下，是不是直接放到esd的detect也可以，我的是818平台，结果放detect里不行，加dsi_read_mode_en也不行

@ddrddr 可能你的framebuffer支持alpha通道，但是填充图像数据的时候没有填写相应alpha数值。检查一下framebuffer格式即可。

谢谢！问题找到了，是排线原理跟玻璃特性有关，由高低电关系导致，电路上加个电阻拉低就OK了。

你好，我目前有个疑问，这块的编译是跟系统绑在一起编译的，是一个大的makafile。现在需要将这块的编译的mackfile 单独弄出来一份，与我现有的代码做融合，这块的makefile怎样提取出来，比如有哪些这个编译得到依赖项怎样才能找到呢？

@zllfdd https://codeleading.com/article/55242723616/

@fuzhikun 烧录时候对于的log发一下看下

@allwinner_account 我也遇到这个问题，修改partion的rootfs_data size，最后pack出来的overlay还是不变，请问你后来找到原因了吗？

然而在A133 android12上，全志的分区表配置中，没有对/data目录进行加密了，启动快了很多

init: Service 'exec 3 (/system/bin/vdc --wait cryptfs enablefilecrypto)' (pid 1753) exited with status 0 waiting took 59.882000 seconds

我最近也遇到了类似启动开机慢的问题，可以跟一下这里的代码，应该是data的文件加密花了59秒导致耗时太长了，源码在android/system/core/init/builtins.cpp 中的 installkey命令，init.rc调用了这个命令去加密data/目录。
不过这个时间可以优化嘛？大佬这么长时间过去了，有没有解决。参考最新的android12代码，我发现android没有做加密/data 目录的动作了（分区表没有配置加密选项）。
