我们试图通过CYPD芯片控制tusb1064(MUX,与PS8740B相同),使主机的4D通道能够将视频数据传输到FPGA。CYPD 在此路径中用作 UFP,但我无法使用引用例程来完成此操作。似乎我无法通过这个获得EDID,但是我们的握手过程似乎是正确的(见附件)。现在我不知道何时在例程中配置 MUX?是否有调用 MUX 的配置?有没有修改方法?

想问下,你使用CYPD4226 NOTEBOOK的代码,在代码中是否做过修改?

从cc log的VDM flow来看,CCG4基本完成了DP配置,HPD也已经拉高,可能还是MUX没有切对。

MUX的操作在datamux_ctrl.c -> mux_ctrl_set_cfg() / PS8740_I2C_Write(), TI这颗MUX我们目前demo里暂时没有找到现成的。

Hi Jade,

As you mentioned ModusToolbox 3.x, let me know if you are checking the code examples for PMG1 on ModusToolbox 3.x?

If yes, please catch the updates in thread - https://community.infineon.com/t5/USB-EZ-PD-Type-C/Is-usbpd-available-in-ModusToolbox-3-x/td-p/38518...

If not, can you clarify more about what you request?

 

Thanks, Fred
