在art_pi_factory工程中，adb软件包中adb_socket_init，是不是要调整到wifi_ready_handler()中，否则若wifi没有开自动重连或者wifi网络比较差连接慢，当前INIT_APP_EXPORT(adb_socket_init) 会先于wifi联网完成前执行，使得adb服务未正确启动，进而导致adb无法使用的情况.
ART-Pi错误提示:
"[7821] E/sal.skt: not find network interface device by protocol family(2).
[7829] E/sal.skt: SAL socket protocol family input failed, return error -3.
[7838] E/ADB iosk: Create socket error

Hi, we are currently considering using your platform to develop a product. We have two questions regarding that.

1. Is the board also compatible / available with the STM32H753XIH6. Are those pins compatible. The STM32H750XIH6 doesn't provide a lot of ram, which makes it unsuitable for our purpouses.
2. Are there Altium files for the Schematic / PCB. It would be important for us to be able to continue production if you decide to cancel the product.

Best regards

你好，可以说下这个工程怎么样编译吗？

手册上写的设备地址是60，为什么程序里面是0x30，求教谢谢

在.cproject 文件中的第50行附近位置中，如果出现了中文字符“Gnu Make 构建器” 会导致studio无法识别为合法的CDT 工程，因此需确保该字段为英文字符 “Gnu Make Builder”

猜想应该是作者发现boot命令会卡死在SCB_DisableDCache函数中，所以把boot命令删除了，解决方案：
最快的解决方案是将编译优化设为O1
从根源上解决是将CMSIS的ARM-software/CMSIS_5@36bd54f
这个commit改动更新到sdk中

net radio例子屏幕显示方向不对，修改lcdspiport里的宽和高不能解决。应该是柿饼显示上层哪里的配置？

最新源码无法编译art_pi_factory工程,麻烦查看一下如何解决

• 切换分支0a69e27997d1e7a45b4d6c532f90873117114ff4后,编译下载成功
  

-应该是更新了rttV4.1的缘故

另外adb怎么使用?我把web文件删了.

根据文档没有找到使用说明 >https://github.com/heyuanjie87/adbd#readme

W25QXX_WriteSR写状态寄存器2时，宏定义W25X_WriteStatusReg2命令码定义出错

引脚也使用cube配置

缓冲区大小问题，这部分是DMA环形缓冲，不过已经分成了两个buffers，为什么在大小还需要乘以2.

DCMI 结束部分的逻辑不太对。
这个函数是在frame complete callback 里面调用的，这部分存在的意义是啥。因为这里已经接收完成可以直接关闭或者重新开始下一帧的接受。

可否使用.gitmodules的方式来引用上游rt-thread的仓库 这样版本更新方便 也可以体验最新版的rt-thread源码 例如：https://github.com/RT-Thread-packages/CMSIS

官方有兼容 hs-probe-firmware 的计划吗？

Hello

art_pi_lvgl does not always start after power off-on. With the simple blink project I don't have this issue...

Any hints?

Thank you

H7上有多块非连续内存分布情况，有高低速总线区别访问、外设定向内存区访问以及Cache数据一致性等情况出现，
因此针对H7这种非连续的多内存分布的管理，需要更加精准的定位到内存地址的定向分配情况。
这个问题该如何处理。@Guozhanxin @whj4674672

STM32H7 是 cortex_m7 的内核，他支持的是双精度浮点。

但是在 RTT-Studio 中设置的是 fpv4-sp-d16 这个是 cortex_m4 的单精度浮点数的设置。

所以应该修改为 fpv5-d16

这个应该修改哪个工程配置文件？

STM32cubePrg can not load w25q64 external flash download algorithm

Pardon for trivial question, but how I upload compiled binary to ART-PI?
Things are complicate for me since I am working on MacOS and RT-Thread Studio not available there.
I am using command line scons to build binary.
I compiled an example project and I see rtthread.bin and rtthread.elf in the build folder.

Usually I would use openocd or removable folder to copy .utf fle.
But I can't find examples on how to do this with ART-PI (perhaps search in english won't find what i am looking for).
I don't want to loose factory code already on the board's flash (WiFi driver, etc) as it would be another problem for me.

Also, is it possible to upload factory code from the board's flash into a file so I can restore it later if i accidentally corrupt it?

Keil FLM 下载算法有问题，下载之后校验失败（并且还是内部flash校验失败？？？），调试发现直接进了hardfault

当前lab_serial中串口输出不一直占用MCU，其通过rt_completion_wait()等待实现，但是调用rt_kprintf输出串口日志时会存在以下问题：
1、如果不是在任务中调用rk_kprintf()，则程序会卡死在rt_completion_wait() -> rt_thread_suspend() -> RT_ASSERT(thread != RT_NULL);
示例：程序刚开始运行rtthread_startup() -> rt_show_version() -> rt_kprintf()
2、如果在任务中，位于临界区调用rt_kprintf()，即任务中先调用了rt_enter_critical()，然后再调用rt_kprintf()，则后续使用rt_kprintf()会出现异常。
示例：运行msh命令netstat，打印的数据不完整，并且后续日志打印都异常了。

. 默認的 factory 工程 easyflash 模塊的初始化 easyflash_init() 未執行，導致無法保存 wlan 密碼到 flash。測試 wifi autconnect 功能 ART-Pi 斷電後就無法再次連接 wifi。順帶出現的問題是雖然保留有 easyflash 區，但是因爲沒有執行 easyflash 的初始化，所有在執行 printenv 時也會提示錯誤。

msh />printenv
[Flash] ENV isn't initialize OK.

我嘗試修改通過判斷是否開啓重連 WIFI 的宏 RT_WLAN_AUTO_CONNECT_ENABLE 來選擇性地執行函數 wlan_autoconnect_init()。目前我將這部分修改放在文件 libraries/drivers/drv_wlan.c，不知道是否合適 😕 ，所以也沒有貿然提交 pr。

我注意到如果使用 基于开发板创建工程，然后选择ARTPI，则RT-Thread版本只能选择v4.1.0，如果我想使用latest版本该怎么做呢

看到 rt-thread master 分支上的 drv_gpio.c 做了较大变动，我们这边需要同步更新嘛？会有什么问题？

请问industry_io_gateway例程中运行在web服务器中的网页是如何制作的？

• 修改蓝牙名称 ART PI 为 ART-Pi
• 修改蓝牙固件读取方式
• 提供网页源文件
• 支持 ADB
• 获取到 IP 的情况，小程序再发送配网指令，不会返回 IP 地址
• ymodem 传输失败
• fal bench 速度比其他例程慢
• 完善 README
• FTP传输回导致终端卡死
• mac 地址不能都是 11:22:33:44:55:66
• web 网页上的资源文件使用 CDN 缓存，提升页面装载速度
• 更新 CDN 地址
• 优化 html 代码

若是新建的BSP例程项目，则无该问题出现

1. RT-Thread Settings中，勾选某软件包下的某个子配置，该配置下的选项可能不会展开（该问题出现在有多个子配置的情况，且之前未配置过该项。目前的一种解决方式：重新取消选择软件包，再次勾选软件包，则可以看到）
2. “搜索”-》“C/C++搜索”-> "搜索字符串" 不支持 带空格的字符串（自动去除了空格）
3. 同时打开多个Studio会出现“无法锁定工作空间”错误提示
4. 同时存在多个ST-Link的时候，不支持ST-Link ID选择
5. “基于开发板”-> " STM32H750-RT-ART-Pi"-> "示例工程", 创建新工程，新工程中的board目录下缺少下载算法文件stldr/ART-Pi_W25Q64.stldr，也因此"配置工程" -> "Download" -> External Loader 未指定外部下载算法文件目录
6. art_pi_factory工程中有处笔误 RT-Thread Settings -> "库" -> "External Libraries " -> "Using RT-Thrad OTA Library"

Hello.

Can I change WiFi chipset? If yes, can you give me quick guide?
In my study, library file in sdk-bsp-stm32h750-realthread-artpi-master\libraries\wlan_wiced_lib is from Wiced platform (Cypress).
Do I have to build a library first at Wiced platfomr?

Thanks in advance.
