@zm12138 在 T113-S3TF卡启动稳定 中说：

[00.593]sunxi flash init ok

MMC已经正常启动了，内核没有输出可以先检查uart配置是否正确

@xjy_5 这个不太清楚了，没有调试过这款芯片。我这边是T507+TC358743实现的

打入以下补丁即可

cd package

填写Sensor输出图像格式

​ sensor输出图像格式定义在sensor_format_struct结构体中，vin v4l2驱动框架通过获取sensor_format_struct结构体成员信息来获取当前sensor输出图像格式，sensor_formats结构体中需要填写的成员是.desc和 .mbus_code。

​ .desc是描述sensor输出的图像格式，本例中gc2053是RGB Raw sensor，故.desc成员填写为"Raw RGB Bayer" 。.mbus_code 为sensor图像数据输出顺序，sensor RAW图像是以Bayer格式传输的（每个像素只表示RGB其中一个分量），常见的Bayer格式为：RGGB、BGGR、GRBG、GBRG，这个可以询问一下sensor原厂或者翻阅sensor datasheet进行查找。.mbus_code 若填错, 会导致色彩偏紫红和出现网格状纹理。

​ 本例中gc2053图像输出格式为RGGB，且当前的配置是10bit mipi接口，故.mbus_code填写为
MEDIA_BUS_FMT_SRGGB10_1X10，若当前调试的sensor配置是8bit输出，
则.mbus_code填写为MEDIA_BUS_FMT_SRGGB8_1X8，按照这种规则进行填写。

static struct sensor_format_struct sensor_formats[] = {
    {
        .desc      = "Raw RGB Bayer", 
        /* 填写 Sensor 初始化时默认的 Bayer 格式，目的是告知主控端ISP当前图像的 Bayer 格式，ISP需要以同样的格式来接收和处理图像数据 */
        .mbus_code = MEDIA_BUS_FMT_SRGGB10_1X10,
        .regs      = sensor_fmt_raw,		
        .regs_size = ARRAY_SIZE(sensor_fmt_raw),		
        .bpp       = 1
    },
};

​ 如果sensor输出图像格式是YUV的话，则需要根据sensor图像数据输出顺序选择YUYV/VYUY/UYVY/YVYU 其中一种，如下：

static struct sensor_format_struct sensor_formats[] = {
	{
		.desc = "YUYV 4:2:2",
		.mbus_code = MEDIA_BUS_FMT_YUYV8_2X8,
		.regs = sensor_fmt_raw,
		.regs_size = ARRAY_SIZE(sensor_fmt_raw),
		.bpp = 2,
	},
};

​ 同时，sensor_get_fmt_mbus_core函数也要将当前sensor的图像输出格式赋值给函数参数*code，有些sensor在翻转后RGB顺序不会自动进行调整，需要主控端ISP需要按照当前sensor翻转后的图像格式更新RGB顺序，避免翻转后出现图像色彩异常的问题，如下，gc2053支持翻转后sensor内部自动调整RGB顺序，所以函数参数*code仍赋值为MEDIA_BUS_FMT_SRGGB10_1X10。

static int sensor_get_fmt_mbus_core(struct v4l2_subdev *sd, int *code)
{
	*code = MEDIA_BUS_FMT_SRGGB10_1X10; // gc2053 support change the rgb format by itself
}

static long sensor_ioctl(struct v4l2_subdev *sd, unsigned int cmd, void *arg)
{
    int ret = 0;
    struct sensor_info *info = to_state(sd);
	switch (cmd) { 
        case VIDIOC_VIN_GET_SENSOR_CODE:    /* vin v4l2框架层在sensor翻转接口被调用后，
        								    通过VIDIOC_VIN_GET_SENSOR_CODE获取当前sensor的RGB顺序 */
            sensor_get_fmt_mbus_core(sd, (int *)arg);  
            break;
        default:
            return -EINVAL;
	}
	return ret;
}

@xjy_5 驱动都不用ISP，ISP是上层用户程序定义的，可以用camerademo抓图测试绕过ISP

对照手册：

• SPI2 地址 0x04027000， 没问题
  

• SPI2 中断号 49，配置时需要减掉SIG和PPI的数量32，也就是17
  

中断号配置错误，应该为17不是18

		spi2: spi@04027000 {
			#address-cells = <1>;
			#size-cells = <0>;
			compatible = "allwinner,sun8i-spi";
			device_type = "spi2";
			reg = <0x0 0x04027000 0x0 0x1000>;
			interrupts = <GIC_SPI 17 IRQ_TYPE_LEVEL_HIGH>;
			clocks = <&clk_pll_periph0300m>, <&clk_spi2>;
			status = "disabled";
		};

重新确认了一下，MIPI 接受的数据格式与MIPI无关，也就是MIPI也可以接收YUV这类数据。

是否是因为后端配置的问题。参考T507的TC358743驱动配置的是MEDIA_BUS_FMT_UYVY8_2X8

@xjy_5 RGB888_1X24 我感觉是直出RGB信号的吧

这个DTSI是在T507上配置的，可以参考一下

@xjy_5 MIPI CSI接收的是RAW数据，不支持YUV这样的

kernel有修改，或者kernel配置文件错误

@hy123456 移动位置后需要删除out文件夹，因为SDK生成的设备的认证信息变化了但是由于SDK移动没有重新生成新的认证

AW平台的DRAM控制器支持地址线REMAP，可以通过REMAP简化外部不同种类的DRAM的连接。

这个REAMP是固定在芯片里的不能自己修改，在电路原理图可以看到REMAP的引脚。

如图，如果需要挂DDR3内存，需要接DDR3的REAMP，如果需要接DDR2，可以接默认的REMAP

举个其他平台的例子：
这里接的是 LPDDR4，使用LPDDR4的REMAP

这里接的是DDR4，使用DDR4的REMAP

Out of memory 没有内存了，camerademo走的拍摄路径是v4l2不是mpp的vipp路径，需要的内存较大，可以尝试拍摄小分辨率的图片测试

@lynnl4 在 摄像头无法获取图像 中说：

[CAMERA] Resolution size : 1920 * 1088

1. 出现重复定义，请问是不是同时勾选了 lv_examples 和 lv_g2d_test
2. 分区表配置的空间过小，FAQ有解决方法：https://r128.docs.aw-ol.com/others/faq/

请按照文档操作：

@huerli 在 T113输出日志，是不是片子坏了啊 中说：

BUG: Bad page map in process S10mdev pte:40cdf59f pmd:41bb1835

主线驱动缺陷导致mdev申请出现NULL pointer。可以尝试使用新内核

烧写安全固件和rotpk.bin之后就再也无法烧录非安全固件了，似乎是KeystoreService未能正常启动

@zhoudaxia3000 目前最新的是1.2.2

@abcdef menuconfig勾选驱动编译了吗

jlt35031c是比较少见的小端屏，但是大部分的SPI屏都是大端屏，所以用jlt35031c时，需要修改sys_config.fex里面的配置项lcd_rgb_order为9.

unsigned char color[4] = {0xff,0x0,0xff,0x0};

这个数组决定颜色，颜色顺序是R（红） G（绿） B（蓝） A（亮度）。

所以红色 + 蓝色，应该是紫色

但是这里由于使用的是SPI接口驱动这个屏幕，并不支持lcd_rgb_order的参数配置。所以在屏幕初始化的时候通过写寄存器配置为对应的接口以支持LVGL的正确显示输出。但是测试命令可能会出现反色的情况。

固件适配板子吗？1.2V电压是DDR4的电压是不是烧录到LPDDR4的板子上了

@masterlu 64G内存，本地磁盘500G

@masterlu
测试复现过程：
出现错误

重开终端清除编译环境和之前编译输出后重新编译正常

感觉是环境配置有问题
试试：

1. 重开一个终端
2. 重新 source build/envsetup.sh
3. 重新 ./longan/build.sh config
4. ./longan/build.sh distclean
5. make installclean
6. lunch

@huangyuhan 没有配置默认保存用户名密码，需要多次输入

@zhouyuan369 删除文件夹内的.repo隐藏文件夹重新拉取

@sunxi source后 mkmpp，你的环境变量没有导入，不能直接make mk文件

@zhouyuan369 网盘要怎么接收后续更新呢，重新下载25G的压缩包吗？

可以看 《Linux_Display_开发指南.pdf》 不过这个也没有设备树的配置描述，更多是源码描述

由于屏幕较大首先精简系统内存，关闭DSP核心，并将 RV 核心移到 HSPSRAM 上提高带宽。配置 LV_COLOR_DEPTH 16 提高帧率降低内存占用

patch 如下，增加了新方案r128-devkit-rgb：161ca91b-f759-4108-8bfc-85114394da0c-r128-devkit-rgb.tar.gz

编译打包即可

700ms启动 LVGL：

@quincy

@sunxi 是独立的视频引擎编码，不使用CPU也不使用NPU

@sunxi

https://github.com/YuzukiHD/Yuzukilizard/tree/master/Software/sunxi-mpp/sample/sample_venc

@sunxi 硬解码调用VE解码，不使用OpenCL

@sunxi V853的NPU运行的是VIPLite驱动模式，不支持OpenCL。Unify驱动暂未支持

@xjy_5 tc358743有现成的驱动，可以试一下

sensor0_isp_used 配置了不使用 ISP

sensor0_isp_used = <0>;

@rookie 但是没有unix编译环境，另外cygwin如果之前没有用过坑比linux下还大

可以在设备树把isp关闭

@rookie xr806不支持Windows下开发编译

GPS模块一般通过UART通讯，4G模块走USB

创建模型
vip_create_network(&network1);
vip_prepare_network(network1);
vip_create_network(&network2);
vip_prepare_network(network2);
设置模型输入输出
// set network input/output buffer
创建执行组
vip_create_group(max, &group); // max = 2
vip_add_network(group, network1);
vip_add_network(group, network2);
执行
vip_run_group(group, max);
获取输出结果
销毁
vip_finish_network(network1);
vip_finish_network(network2);
vip_destroy_buffer // 销毁input/output
vip_destroy_group(group);

UDISK属性写错了

@ddrddr 看一下图层的设置，是否有图层覆盖

adb 可用时可以直接读取 /dev/by-name/rootfs 将rootfs导出来

adb pull /dev/by-name/rootfs rootfs.img

也可以push到tmp文件夹然后dd写入

adb push rootfs.img /tmp
dd if=/tmp/rootfs.img of=/dev/by-name/rootfs

@uccccc 在 为什么添加Gstreamer后会报这个错误 中说：

@awwwwa 麻烦问一下这个应该怎麼添加，有没有相关的资料亚

https://openwrt.org/docs/guide-developer/packages

内核配置去掉宏：CONFIG_STACKPROTECTOR和CONFIG_STACKPROTECTOR_STRONG。

@fantasya git command failure

没安装git

24993+0 records in

6398208 bytes (6.4 MB) copied, 0.0271082 s, 236 MB/s
ERROR: dl file rtos_riscv.fex size too large
ERROR: filename = rtos_riscv.fex
ERROR: dl_file_size = 1579 sector
ERROR: part_size = 1000 sector
ERROR: update mbr file fail
ERROR: update_mbr failed

这是因为 rootfs.fex 太大了，分区容量设置过小。

解决方法

• 确定打包使用的分区表

运行打包命令，找到打包使用发分区表。例如这里使用的是 sys_partition_xip.fex

• 编辑分区表

使用 cconfigs 命令进入目录，找到打包使用的分区表，编辑修改

• 找到上面报错的行，修改 size 选项，单位是扇区。对于 NOR 方案请对齐。这里我们修改到 7000

• 重新打包，正常通过

没有交叉编译，gstreamer没有配置交叉编译工具

@xjy_5 kernel启用loop device了吗

单独勾选这个命令编译

@vincent1 需要修改ffmpeg从vipp获取数据，或者使用mpp推流不使用ffmpeg

mipi摄像头需要走vipp通路，video0只有一个很基础的v4l2设备，上层需要更多的处理，例如isp，3a等，usb走uvc直接对接v4l2提供全部功能

@kkkcxf 在 R329 tina 启动卡死问题 中说：

Waiting for root device /dev/mmcblk0p4...

rootfs配置问题，不是卡死了而是等待挂载ROOTFS

@yofa2008 img不是磁盘镜像文件，是专有的压缩格式，不带分区表。可以用OpenixCard转换为dd可以写入的带分区表的镜像

R329不支持libAWIspApi，需要取消选择这个包

@woxow 把你的proxy代理关了

@uccccc
你的分区有两个name，怎么能正确识别呢

先上固件：

9724ff03-b4bc-4a07-8bac-05431383d983-gaviarhandhelda.img

@bigfly colorbar正常吗

源碼如下：

src.zip

@mysteryli 可以到 out/v853/xxxx/openwrt/build_dir/target/camerademo/ipkg-install/usr

@xjy_5 在 抓图报错[VIN_ERR]isp0 width error，求给个排查思路 中说：

首先，isp配置错误

[VIN_ERR]isp0 configuration error

isp fifo为空

[VIN_ERR]isp0 internal fifo full

isp 帧错误

[VIN_ERR]isp0 frame lost!

如果不需要使用isp，可以修改sample的源码删除isp处理部分，并且修改设备树禁用isp

@yelong98 mkernel 强制重新编译内核试试看

mmo camerademo -B

@liefyuan

这里下载这个版本：https://www.aw-ol.com/downloads?cat=5

@gaowei15537316965 SPI驱动参考 Linux 编写spidev驱动即可

F1C100s 与 STM32 通讯是需要通过外设接口，例如UART，SPI，IIC，SDIO来通讯，你看到的这个 DMA 控制器驱动是给STM32MP用的，不是给F1C100s用的

为什么F1C100s的DMA控制器驱动需要使用 st,stm32-dma 而不是 allwinner,sunxi-dma

Linux都没启动，先检查为什么Linux没启动

@sofia USB 2.0 的速率，大约为 34MByte/s

不正常，进行了如下实验：

• 准备开发板：T113-S3 EVB1，eMMC 型号：FEMDRW008G-88A39

• 1.1GByte 固件一份，

下略

考虑可能的问题：

1. 使用USB HUB进行刷写，影响速率
2. 使用的 eMMC 速度较慢
3. USB 连接不稳定，出现断连情况
4. 供电不足，cpu 在烧写状态下缺电
5. eMMC 布局走线不合理
6. 选择全盘擦除升级而不是分区擦除升级

可以走UAC协议，adb forward

ls /dev 看一下输出

@liu11372650 在 D1s芯片烧录melis固件启动报错，大家帮我看看咋回事 中说：

0x000000004003049c

根据这个地址，objdump出来elf去找一下是哪一个函数报错

@sofia 我记得需要在小机运行一个uvc的程序，因为vin框架和isp通路与nxp的不一样，nxp是软件isp这个是硬件isp，可能有些地方需要适配

@jinxiangwzh 不需要，USB3.0支持OTG

A523，CSI规格16M不过ISP是8M的

这个UVC需要本地运行一个UVC的服务端调用摄像头通路才可建立，否则不会上报为UVC设备而是复合设备
