On our custom carrier board we have added a third USB port. With JetPack 3.3/L4T 28.2.1 if I patch the devicetree as mentioned on https://elinux.org/Jetson/TX2_USB and the linked forum post then the third USB works. When I upgrade to JetPack 4.2/L4T 32.1 and apply the patch the third usb does not wo…

Hi all, I managed to get this working. It seems like the new L4T sets the vbus-supply within the xusb_padctl@3520000 node as well as the power tree? I’ve rolled my changes into the patch below Index: hardware/nvidia/platform/t18x/quill/kernel-dts/tegra186-quill-p3310-1000-c03-00-base.dts <+>UTF-…

Hi, USB lane mapping is different on r32.1. We are working on the document. Will update.

Hi @DaneLLL - I also have this issue and it’s currently blocking our development under JetPack 4.2. Do you have an estimate on when the documents will be ready? Thanks

Awesome! I’ll give it try. Thanks!

Thank you very much, I was getting mad and saw your post. That works like a charm!

I ran into a problem that I thought was the same as above. I’m sharing it here to hopefully save developers some trouble. If plugin-manager is disabled on R32.1 the USB3 port will not work. It will look very much like the problem in this post but the patches above will not fix the problem. I’m not …

We were facing same issue when work on custom board. After apply #4 patch able to communicate using USB. We are using USB 2.0 as gadgetFS device(OTG) mode in Jetson TX2(Jetpack 4.2.1) and communicate with Windows Host PC using with libUSB driver. In our application, we transfer separately a .bmp im…

Hi pranay.joshi, This topic is about device tree of USB lane mapping. Your issue looks different. Suggest you start a new topic.

I update my version to Jetpack4.3. I reference the path to modify my dts files,the OTG port work well,but why my USB3.0 cannot work?
