Jetson Linux 34.1 can not bring up XAVIER lcd

Robotics & Edge Computing Jetson & Embedded Systems Jetson AGX Xavier

  1. I use L4T Driver Package of Jetson Linux 34.1 to flash xavier dev board, the xavier can bring up successfully and lcd display normally.
  2. Then I build an Image from source code of Jetson Linux 34.1, and replace the Image in the target with the one I just built.
  3. The problem is that: the lcd can not bring up, but log can be output from serial port, and I can log in from serial terminal.

What is your step to build kernel? Do you know that jp5.0 is using new toolchain?
