[FAQ] [TDA4VL] 通过 DP 端口无法显示电路板

问题 1

我使用的是 TDA4VL 电路板和 8.0.3 SDK,按默认设置构建和制作 SD 卡后,它可以正常启动,但通过 DP 端口无法显示,而且无法通过命令 modetest -M tidss -p 获取有关显示驱动器的任何信息,

 您能帮我解决这个问题吗? 

 

1

请查看随附的补丁,它可以在 TDA4VL 器件上启用 eDP 显示。请在 ti-processor-sdk-rtos-j721s2-evm-08_00_03_05\vision_apps 文件夹中应用补丁 Display_On_J721S2.patch,重新编译 SDK 并将其安装到 SD 卡上,然后将 k3-j721s2-vision-apps.dtbo 复制到 SD 卡的 rootfs/boot 文件夹。 

/cfs-file/__key/communityserver-discussions-components-files/791/8032.Display.zip

 

问题 2

我根据您的提示应用了补丁并安装了 SD 卡,但问题仍然存在,我需要您的进一步支持。 

2

您在 EVM 上检查了吗?因为做出上述更改后,我能够在 EVM 上看到 eDP 显示。

问题 3

是的,我按如下步骤在 EVM 上进行了检查:

  1. 在 ti-processor-sdk-rtos-j721s2-evm-08_00_03_05\vision_apps 中应用该补丁;
  2. 创建 vision_apps -j4;
  3. 创建linux_fs_install_sd;
  4. 将 k3-j721s2-vision-apps.dtbo 复制到 SD 卡的 rootfs/boot 文件夹;

5.将 SD 卡插入 EVM,给 EVM 上电; 

完成这些步骤后,我可以通过 minicom 捕获引导日志,但显示器上没有显示任何内容。 

我将检查主电路板是否存在硬件问题

 

3

您使用的 eDP 显示是什么? 

不同的一点是,我更改后只测试了 HP 显示器。对于其他显示,我们可能需要更改更多,尤其是在电路板上启用 eDP_PWN 信号。这可以通过配置由 i2c1 控制的 IO 扩展器来完成。但由于某些 i2c 问题,目前在 vision apps 的 apps_utils_soc.c 文件中禁用了此功能。

 

问题 4

我使用的是 DELL 显示器。

为了测试此问题,我更换了主板,但仍然会出现问题。

您是否需要一些其他信息来调试此问题?我在下面附上了引导日志,可能有助于调试此问题。谢谢!

答 4:

您能对代码进行一些小改动,然后再尝试一下吗? 

在 ti-processor-sdk-rtos-j721s2-evm-08_00_03_05\vision_apps\utils\dss\src\app_dss_soc.c 文件中,您能否按照下面所示更改 appDssConfigureDP API,重新编译 SDK 并尝试 eDP 显示?

void appDssConfigureDP(void)
{
#if defined (SOC_J721E) || defined (SOC_J721S2)
    Board_STATUS b_status;
    Board_IoExpCfg_t ioExpCfg;

    appLogPrintf("DSS: Turning on DP_PWR pin for eDP adapters …!!!\n");

    #if defined (SOC_J721S2)
    ioExpCfg.i2cInst = 4U;
    #else
    ioExpCfg.i2cInst = 1U;
    #endif
    ioExpCfg.socDomain = BOARD_SOC_DOMAIN_MAIN;
    ioExpCfg.slaveAddr = 0x20;
    ioExpCfg.enableIntr = false;
    ioExpCfg.ioExpType = ONE_PORT_IOEXP;
    ioExpCfg.portNum = PORTNUM_0;
    ioExpCfg.pinNum = PIN_NUM_0;
    ioExpCfg.signalLevel = GPIO_SIGNAL_LEVEL_HIGH;

    b_status = Board_control(BOARD_CTRL_CMD_SET_IO_EXP_PIN_OUT, (void *)(&ioExpCfg));

    if (b_status == BOARD_SOK)
    {
        appLogPrintf("DSS: Turning on DP_PWR pin for eDP adapters …Done!!!\n");
    }
    else
    {
        appLogPrintf("DSS: ERROR: Turning on DP_PWR pin for eDP adapters failed !!!\n");
    }
#endif
}

 

问题 5

 我应用了您的补丁,但仍然会出现这个问题。您有没有其他方法来确认显示驱动器一切正常?

5

您是在进行上述更改后重新编译 SDK 了吗?因为完成上述更改后需要重新编译 SDK。

如果仍然不起作用,那么您是否确定所使用的显示支持标准 1080p 信号?您能检查一下吗?

 

问题 6

我按照以下步骤在 SDK 中应用您的补丁:

  1. 在 ti-processor-sdk-rtos-j721s2-evm-08_00_03_05/vision_apps/ 中创建 vision_apps -j4;
  2. 在 ti-processor-sdk-rtos-j721s2-evm-08_00_03_05/vision_apps/ 中创建 linux_fs_install_sd;
  3. 按 SD 卡模式引导 EVM;但显示器不显示任何内容。

我的操作有什么错误吗?

 我还将子板和 SD 卡连接到其他主板来测试此问题,结果是一样的。您需要一些关于这个问题的日志吗?

 

6

我看不出导致失败的任何其他原因。您使用的显示设备是否支持 1080p 分辨率?如果可能的话,您能否将显示设备连接到笔记本电脑,读取 EDID 并检查它是否支持 1080p 分辨率? 

问题 7

显示器支持 1080p 分辨率,我的笔记本电脑可以连接它并正常工作。

问题 8

我检查了一些配置文件,我不确定 app_cfg_mcu2_0.h 是否更改正确,能将您工程中的这个文件分享给我吗?谢谢!

8

当然可以,您可以尝试使用随附的文件、重新编译 SDK,再试一次吗?
