How to use USB1 and USB2

  1. On our carrier board, we did not use the RTS5411S chip in the hardware design of the USB1 port, and used a direct connection. At this time, how to use the USB3.0 port, and what driver support is required? ? PS: It can recognize U disk, but we need to mount it by ourselves
  2. How to use USB2, the M.2 interface is used on the official carrier board, now we need to use her as a normal USB2.0 port to drive the 4G module, how should we use it, and which official driver support is required? ?
    Picture 1 to picture 3 are USB3.0 design, only need a hardware interface, thank you for your answer

There is USB connection example in OEM DG in DLC for your reference. USB2 can be used as normal USB port similar as other ports.

Hi,

Please refer to Jetson Nano adaptation guide to modify the device tree.

On our carrier board, we did not use the RTS5411S chip in the hardware design of the USB1 port, and used a direct connection. At this time, how to use the USB3.0 port, and what driver support is required? ? PS: It can recognize U disk, but we need to mount it by ourselves

What do you mean “it can recognize U disk but need to mount it by yourself”? The USB3.0 can be detected but you need to mount the disk by yourself?

7

yes

8

Then the usb can work. The disk mount has nothing to do with the usb driver.

9

The hardware interface USB2 can not recognize the mobile USB flash disk，This interface is USB2.0

10

What driver we need to install

11

Not driver. You need to read the document modify the device tree.

If you don’t know what is device tree, please find a software engineer who is familiar with linux device tree.

12

What documents do we need to read about modifying the USB2 interface to ordinary USB? ? ? Please give us some reference documents, thank you！

Hi All, I also have a similar case where a custom carrier board is being designed without RTS5411S chip.

will the attached image configuration be fine from hardware connection point of view for connecting to USB 2.0 and USB 3.0 devices ?
