Hi, Compared with USB not working, the problem of crashing( cpu woking, desktop programs don’t respond ) after entering the desktop is more urgent. Do you have any suggestions? Thanks.
Hi, is DP.I use a chip to split the HDMI signal into two and transmit it to the DVI interface and the HDMI interface to connect the display. Unfortunately, now HDMI and DVI do not have a signal, and they cannot be displayed after being connected to the monitor. During the test, neither HDMI nor DVI had a monitor connected. Although DP has a signal, it will get stuck.
I try to open the Qt program through the serial console, and it returns something like this:
Hello, as you said, the dp does not seem to be stuck. The reason is that the HDMI signal is not output to the display, but the chip of “HDMI 1to2” is given, and when the DP is plugged in, the system uses the DP-connected display as an extended display, making us think that it is stuck, but it is not. Thank you very much for your patience, I will continue to test USB and other functions next.
您好，我不是简单的将HDMI信号1 to 2，而是采用芯片将HDMI 1 to 2，请问这样也不可以吗，但我现在确实想并联几个屏幕同时显示相同内容。谢谢。
Hello, I am not simply dividing HDMI signal 1 to 2, but using the chip to divide HDMI 1 to 2, is this not okay? But I do want to parallel several screens to display the same content at the same time now. Do you have any suggestions, thank you.
您好，这是关于USB的原理图，和输入lsusb command得到的结果。我在TYPEA USB3.0(原理图中的J32 )的接口插入了一个鼠标，但似乎并没有被识别到。MICRO_B (J28) 似乎可以正常工作。
Hi @WayneWWW , This is the schematic of USB ,and the result of “lsusb”. A mouse was plugged into TYPEA USB 3.0(J32 in schematic ), but it was not recognized and did not work properly. MICRO_B (J28) seems to work fine.
HI, We did not change the schematic given by the official when designing USB, my understanding is that there is no need to change the device tree, but USB is not working now, please give me a little advice.
Hello, thank you very much for your advice. In my carrier board, R511, R478, C339 are not soldered. VDD_3V3_SYS or 3V3_IO_PG is 3.3V. But my USB didn’t work.
您好，非常感谢您的建议。在我的底板中，R511,R478, C339 没有被焊上。VDD_3V3_SYS or 3V3_IO_PG是3.3v的。但我的USB没有工作。
Hi，I found that my crystal oscillator is not working. The HUB_XTAL_OUT (pin75) of the RTS5411S-GRT is high.Are you experiencing a similar issue？ Thanks!
