We ported the Jetpack 5.0.2 (L4T r35.1 GA) to our customized board with Xavier NX module on it, and it works fine so far. Now, we’d like to enter UEFI menu to select the boot device under serial port.
However, UEFI did receive my “ESC” key and enter UEFI menu, but after that, menu is not responding no matter I input any keys, like ESC, enter, f1, arrows,…
Here’s my test configuration:
- Serial Port : 115200 8N1 no flow control
- Serial Terminal: gtkterm
- Hit ESC at host PC side.
- We have a USB3.0 hub IC bridging USB keyboard and Xavier NX’s USB port.
Some hints from my tests…
- I can enter menu by hitting ESC, so there’s no USB3.0 hub IC driver issue.
- The cursor in the menu looks refreshing quickly and jumping randomly on the screen. It looks like there’s a running program blocking the keyboard input.
