I’m using custom carrier board that I designed myself. There is no problem using USB port when I’m using L4T 32.2.1 and jetpack 4.2.2. However, I need to update L4T version to 32.4.3 for my new application to use jetpack 4.4. After the update, USB doesn’t work. What I don’t understand is that it’s working on the evaluation board. The schematic for USB part in my custom carrier board is as follows.
If it is the problem of S/W configuration, I think it should show the same problem on the evaluation board. If it is the problem of H/W design, it should be happened with L4T 32.2.1.
