DS90UB953A-Q1: USB3ANY连接问题

Part Number: DS90UB953A-Q1
Other Parts Discussed in Thread: TDA4VM, USB2ANY, ALP, DS90UB954-Q1EVM

您好,我们目前正在打算使用ds90ub953、ds90ub954和TDA4VM使用serdes通路,但是目前ds90ub953暂未获取。

因此我们打算使用ds90ub954中的pattern generator生成图形模拟输入信号。现有两个问题想明确:

1.我们目前将ds90ub954供电,并将其与TDA4VM相连,并且使用usb线将ds90ub954的J2端口与电脑的usb端口相连。LaunchPad成功识别ds90ub954。如果要生成内部图形,这样连接是正确的吗?还需要usb2any这个器件吗?

2、如果需要使用USB2ANY,我们在文档中看到“There are two methods to use the USB2ANY to communicate with the 953/954 EVMs. The first method is to simply connect the USB to Mini-USB cable to the USB port of your computer and the Mini-USB ports on the EVMs, J9 for the 953 EVM (see Figure 2-2) and J2 on the 954 EVM. If using the first method, skip to Section 3.3. The second method is to use the pinout of the USB2ANY. Figure 3-2 shows the USB2ANY pinout with the I2C pins highlighted. Typically, jumper wires are used to connect these to the 953/954 EVMs. ”

第一种方式中没提到使用USB2ANY,我可以理解为第一种方式就是使用usb线缆将ds90ub954与PC相连吗?如果是这样的话是否就对应了我们的连接方法?

目前,我们做的工作有:

1、ds90ub954供电,并将其与TDA4VM相连,并且使用usb线将ds90ub954的J2端口与电脑的usb端口相连

2、launchpad成功识别954,并且可以读取其I2C地址。(我们注意到我们没有pattern generate 这个选项卡)

3、运行脚本文件,间接生成内部图像。raw12 1920*1080

4、查看CSI_STS的值,发现始终为0;
