hi

请问一下怎 样在开发板中支持串行解串器ub954-ub953+sensor(这个不用i2c控制)

ub954是

DS90UB954-Q1EVM 评估板 | TI.com.cn所购买的板子

    可以使用Adafruit SAMD来支持这个开发板。

    请问一下，我们这ub954+ub953+camera方案，硬件这边已经可以检测到图像及相应的波形

    解串器显示是1080,1920

    软件上怎样开启或者修改代码，才能获取到YUV图像图像，或者说测试取到YUV图像命令是

    除此之外:

    我们这边读相应csi寄存器

    CSI_RX_IF_VBUS2APB_INTEGRATION_DEBUG

    devmem2 0x30101060
    /dev/mem opened.
    Memory mapped at address 0xffff891ae000.
    Read at address 0x30101060 (0xffff891ae060): 0x10000000

    bit31-28始终是1表示当前状态WAIT_FOR_PACKET

    我们发现在VH平台(这款camera sensor+ds953+ds960调通过)

    如下 VH bit1-0是2,表示当前状态PAYLOAD_DATA

    devmem2 0x04504060
    /dev/mem opened.
    Memory mapped at address 0xffffb1015000.
    Read at address 0x04504060 (0xffffb1015060): 0x20000000

    硬件上均为ti evm板,如下6脚量到有波形,波形与VH调的一致

    UB954-Q1 EVM有两个Samtec MIPI连接器，一个在顶部，一个在底部。您正在使用的一个在底部显示在您的图片。要使用这个，您需要填充如下所示的零欧姆电阻(来自UB954-Q1 EVM用户指南)。

    另一种方法是在顶部使用Samtec连接器，而不填充这些电阻，如下所述:

    配置UB954-Q1 EVM:

      配置J16报头选择3.3v
      短跳线J23使用0x3d为I2C地址

    使用此连接AM62A SK到UB954-Q1 EVM：https://mou.sr/3jYCoP0

    有几个问题想咨询:

    1.

    这个代码替换到我的sdk对应ti-processor-sdk-linux-am62axx-evm-08.06.00.45路径上有很多报错

    还是我不用管这个代码,只需要用自带sdk ti-processor-sdk-linux-am62axx-evm-08.06.00.45的对应文件

    2.

    我这边用

    setenv name_overlays k3-am62a7-sk-csi2-imx219.dtbo,将

    如果您使用的是SDK 8.6，那么只需查看ti-processor-sdk-linux-am62axx-evm-08.06.00.45中的代码。

    我不完全理解您的第二点。

    您是否介意在启动板后共享“v4l2-ctl——list-devices”和“media-ctl -p”的日志?

    3.用gst命令获取yuv数据（解串器的CSI数据应该是yuv422_8b）

    4 .ctrl+z切到后到，执行

    5. sh C0.sh（des,ser初始化）

    6.fg切到前台，界面没有显示camera图像

    7.发现中断，只有4，并没有增长，调试发现dma接收数据不正常

    出现这种现象是我的gst-launch-1.0命令有问题嘛，还是驱动设置有问题，这边需要怎样分析，（camera sensor与厂商沟通过，从954读到的分辨率及波形正常，且这个camera在tda4 vh中点亮过）

    您的gst管道有“宽度=1920，高度=1080，格式=YUY2”，但“media-ctl -p”显示“SRGGB12_1X12/1936x1100”。

    请检查这个线程是否对你的用例有帮助:e2e.ti.com/.../sk-am62a-lp-debug-about-csi2rx

    参考后sdk按如下修改后更新im390ko,开机后设置如下命令：

    media-ctl -V '"ds90ub953 4-0044":0 [fmt:UYVY8_2X8/1920x1080 field: none]'
    media-ctl -V '"ds90ub960 4-003d":0 [fmt:UYVY8_2X8/1920x1080 field: none]'

    ，CSI_RX_IF_VBUS2APB_STREAM0_STATUS 0x30101048 有2，3变化，说明dphy有数据，

    但

    CSI_RX_IF_VBUS2APB_ERROR_IRQS 0x30101028 显示bit 8置位

    项目急啊，大哥哥

    我们模组型号

    SG2-OX03CC-5200-FPDLink
