@awwwwa 你好，请问打开了UART0的DMA之后卡在这个地方是为啥呀7c855583-631f-4643-8d8d-f0835404c26b-1704969112860.png

@awwwwa
找到了。

@awwwwa 嗯嗯，好的，感谢大佬！

@wj8331585 1.0正式版发布，目前都是内测版SDK

@daizebin 好，我试试，是D1S 的

@z15242116489 dts节点要放对应的i2c下面，你放dtsi是没法识别到设备的。
最新社区内核代码github有
https://github.com/torvalds/linux

@gaowei15537316965 在 f1c100s可以改成rgb565，是不是只需要修改设备树就可以了？ 中说：

rgb888

由于我通过 VGA DAC 将设备连接到 VGA 显示器，因此我使用 dumb_vga_dac 驱动程序。
该驱动程序允许您选择多种模式。 这就是为什么我“即时”切换模式。

您正在使用驱动程序 "panel-simple"。 该驱动程序仅允许一种模式。

对于 16 位，最有可能需要指定格式：

.bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG,

但不是
.bus_format = MEDIA_BUS_FMT_RGB565_1X16,

无论如何，在 sun4i_tcon.c 驱动程序中，sun4i_get_pixel_depth 函数提到了格式

MEDIA_BUS_FMT_RGB666_1X7X3_SPWG

需要尝试一下。

@xiaogcc23333 https://www.cnblogs.com/rogerlee1986/p/17342479.html可以参考一下，但是不同cpu的TSC时钟源估计不一样。
我放弃全志方案了，公司项目有时间要求，换x86平台搭xenomai轻松多了，实时性也强很多

@nideyida 主要是用的人太少了，现在虽然价格便宜性能好，但是要想全用起来要掉层皮的……好难啊，这芯片有ledc控制器，但是没有一个好用的上层驱动库，不像esp32 的Arduino框架下那个fastled那么好用，要是能移植一个进来就好了

@yuzukitsuru T113-i SD 采用你嵌入的DMA控制器功能，出问题的reg 值，有DES不可用标志

msys卡壳了，

不知道 cygwin 是如何解决这个 8192超长命令行问题的?

@luojia65 没太理解你说的几个代码就跳转的流程，但dram初始化代码，存储驱动代码得有，这些都得加载到sram或dram上运行。

@xiaowenge 你是全志原厂的么 ，原厂才5个啊😁 全志都有candece的ip授权 搞几个xplorer工具授权应该很简单呐🤥

@randolph 放个效果😬

@whycan 在 D1s + Toshiba LTPS 3.5寸 RGB888屏 安排上了 中说：

@whycan

D1s 已经成功初始化，并用RGB HV信号点亮了屏幕，效果杠杠的。

调个屏幕尺寸看看显示效果

不错参考yuview里面的示例程序，在F1c200s上实现了直接读取AHD解码芯片出来1920*1080的NV21数据并在LCD上实时显示。

大佬，为啥SDK开发说明没有了，不知道怎么玩呜呜呜

@oiouou123 恭喜跑通hellow world！下一步 改变世界！

@randolph OK,最近几天事有点多，忙完就整一个😁

我用GigaDevice的也遇到了同样的问题，请问解决了吗

@juggernaut 不能，可以用dfu刷写

太骚了，厂商直呼内行

@whycan 感谢，我使用万用表测试一下

@wyljkl 开机logo是保存在boot-resource分区内的，在Linux系统中挂载这个分区，替换开机logo即可

你好，为什么挂载不了这个分区，不知道问题出在哪里：

@frank_yuan 刷启动卡

我看過你的很多帖子。 信息非常豐富且鼓舞人心。 首先，如果文字不清楚，我很抱歉，因為我使用的是電子翻譯。

眾所周知，芯片危機和市場供應的不確定性迫使許多開發商轉向替代解決方案。 對我來說，我相信全志可以做出一個很好的選擇，即使它也很難進入市場，但與其他芯片相比，它仍然更容易採購。

我正在看哪吒板子上使用的D1-H。 D1-H SOC 的規格非常適合我的項目，但我只是不知道從哪里以及如何開始。 我想知道是否可以在沒有 Linux 的情況下將 D1-H 與 FreeRTOS + LVGL 一起使用。

另外，如果這裡有人提供使用全志SOC芯片的開發和諮詢服務，我很樂意與他們討論我的項目。

謝謝你！

这里提供的是使用设备树方案的配置名称，对于使用 sys_config.fex 的方案可以对照这里的设备树检查，配置项差别不大。hispi与mipi软件上只需要修改sensor驱动，不需要修改 V4L2框架，更不需要读写寄存器。具体方法参考 《Linux_MIPI_CSI_开发指南.pdf》（需要FAE提供）。

这里提供设备树的配置：

有大佬验证过了么？

请问你最终解决了这个问题了吗，是如何解决的，我也遇到了同样的问题

@mangogeek 大佬能不能放一个boot0修改了的文件啊

@x_17866824910
find target/ device/ -name defconfig

@xiaowenge 是tina linux吗?

@evler 那就不清楚了 😥

@allwinnertech 是的就是想在uboot 中配置好，但是没有成功。

@tianjiangfuzi 那yolov5你编译成功没？

@lgkgkfg 谢谢，设备树我已经会更新啦

非常感谢，然后我找您的方法，ifconfig 发现eth0没有加载，然后我尝试抓了一下驱动的日志，发现抓不到 gmac的驱动日志，这说明网口真的坏了吗，还有论坛上的出厂测试固件好像和开发板开始自带的固件不一样吧，sdk的默认配置烧出来也跑不了摄像头的sample，tina5.0不带eyesee的组件还需要打npu的补丁？和eyesee的补丁？

@tianjiangfuzi 是的，nn只支持uint8, int8，float会被转换到pp计算。nbinfo是一个软件读取解析nb文件的，可以看到他在哪一个核心上运行

@whycanservice 三剋有

@lyscut 要在哪里设置呢？

@xiaochusheng
mipi点亮大佬方便指导下吗，q951196174

@justyu666
可能C库不一致，上面SDK里面有一个是 glibc, 有一个是musl。

@frankisme V85X

@whycan 这些我真的改了，现在搞不明白，目前mmc2和uart0不冲突，为什么mmc2 not
found ,另外内核启动介质是在sys_config.fex里面配的吗？

@yuan123 今天才看到，搞定了没，加我qq 491532763

@sofia 考虑被Linux接管了，具体查看寄存器情况

@weichengjie T113 上同时开启CAN0,CAN1,及4G通信。都是正常的。原来使用CAN0就影响到4G模块的原因找到了。是在设备树文件上，USB的节点里有PB3的定义。去掉就正常。

@wyljkl 您好请问，我这边是lvds转edp，用的ncs8801这个芯片初始化放在哪里去做，求帮助

@bayche 在 支持DDR4的芯片（如H616）想用DDR3时引脚该怎么接 中说：

方便接线内存重新排布的

微信图片_20230406085013.jpg

请问，关于DDR地址线(SA0~SA16)这一块引脚的复用配置，有文档说明吗

@whycan 可以了，会丢包，丢包可能是飞线的原因，之前同事没有把crs接到pe0，phy芯片的crs直接拉低了。用内部时钟和外部晶振都能起来了。感谢🙏

@whycan 还是没有gpiochipX，是这个样子吗b8bdee45-7d5b-4ef0-996b-5c268e843e4d-image.png

@dyufeimen 问题解决了，自我回复一下！缺少libasound是因为在package/multimedia/sdl路径下的Malefile中缺少依赖，增加DEPENDS:=+alsa-lib即可解决。
当然也可以disable-alsa也可以解决此报错问题

@whycan 晕哥你好，请问如何实现lvgl和底层视频带透明度的叠加，可以提供一点思路吗

cpu空闲占用高的情况换用glibc编译后也正常了，看来这个sdk里面的musl库还是有些bug的，也听大佬说改用官方最新版本的musl库可能也会好。glibc编译搞定了就不折腾这个musl了，感觉还是glibc靠谱吧。

@sunxi 是独立的视频引擎编码，不使用CPU也不使用NPU

@wellschan 在 关于V851S的LCD 5.5寸MIPI屏幕驱动分享 中说：

@zuoyi 你好，这个屏幕支持2 LANE的，可以在全志的设备树里面设置为2 LANE，同时驱动初始化代码里面将默认的命令：BA 33 81 05 F9 0E 0E 20 00 00 00 00 00 00 00 44 25 00 91 0A 00 00 02 4F C1 00 00 37
改为：BA 31 81 05 F9 0E 0E 20 00 00 00 00 00 00 00 44 25 00 91 0A 00 00 02 4F C1 00 00 37

可以查阅屏幕IC手册的命令：BA
里面有表格介绍：
d78eddc4-4dcc-4b87-8c15-eef378e1d30a-image.png

你好，原来是3lane通信，现在修改成2lane通信，除了修改设备树3lane->2lane 和 BA寄存器，其他地方还用修改吗，比如时钟等等

已放弃，勿回复。

我也遇到了这种情况，是没有安装busybox的原因，安装完就好了。

使用dma模式搬运数据，需要打上如下补丁：

ledc在dma模式的代码存在问题，已修复该问题，ledc的dma通道之前也没有支持，需要添加上

@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); }
