您好！

您是否可以压缩.json 文件并将其发送到此处？ 将配置加载到 Web GUI 时遇到问题、您还能检查您使用的是哪个版本的 Web GUI 吗？

此致

当然可以。 我 已按照以下方式附加了存档。

e2e.ti.com/.../NewProject_2800_1_2900_.zip

您好

感谢您提供.json 文件。 请允许我花点时间来研究这一点。

此致

您好！

我发现网络 GUI 存在一个潜在问题。 看起来此时像是 Web GUI 错误、需要进一步调试。

此致

尊敬的 Tommy：

您是否提到过 Web GUI 中的 TPS25750 Application Customization Tool？  如果是、调试和解决此问题需要多长时间？

您能否根据我们的要求和要求向我们提供补丁捆绑包数据  

Unknown 说：

NewProject(1).zip

来验证该功能？

谢谢。

此致、

戴夫

您好！

由于 TPS25750 Application Customization Tool 将 很快弃用、因此我认为这一错误不会很快修复。

我需要寻找另一种方法来为您生成二进制文件。 请允许我在此花点时间。

此致

尊敬的 Tommy：

没问题、谢谢。

此致、

戴夫

您好！

希望我可以在星期五之前向您提供。

此致

您好！

您能否在 D+/D-线路上提供波形捕获？ 我想交叉检查,如果我看到同样的事情在我的最后。

此致

您好

您可以尝试此.json 文件吗？

e2e.ti.com/.../bc1p2_5F00_change.zip

此致

尊敬的 Tommy：

我们已经尝试了您提供的.json 文件。 我们发现、无论器件连接到 DCP 还是 SDP、都未对我们的器件充电(无法使用电流探头测量充电电流)。 但当我们连接到充电端口时、我们测量了 D+ D-引脚、发现好像有一个检测波形。  我们捕获了测量的波形图形以供您参考。 我们希望您能继续帮助我们解决问题或与我们分享任何建议。

连接 BC1.2适配器(DCP)

连接 PC 的 USB 端口(SDP)

谢谢。

此致、

戴夫

您好！

您希望支持哪种类型的 BC1.2设备、现在该设置已设置为仅支持 DCP。

此致

尊敬的 Tommy：

我们发现、读取寄存器(例如0x3F)可以在 TPS25750主机接口技术中获取检测到的器件类型
参考手册、包括 SDP、CDP 和 DCP 检测。 我想知道除 DCP 或 CDP 充电外、它是否还可以支持 SDP？  我们希望所有三种类型都能在可能的情况下获得支持。

谢谢。

此致、

戴夫

尊敬的 Tommy：

下面的屏幕截图是 DCP 充电器连接到我们器件上的 USB Type-C 端口时的 I2Cs 日志。  我们发现、该设备从 DCP 充电器汲取电流、但电池未充电。 我们不确定 BQ25713的设置是否导致了此问题、因此我们为您提供日志以供参考。

谢谢。

此致、

戴夫
