hello momo_chen,

you’ll need to update these 5 files,
please disable combined uart and assign the correct uart port for the logs.

  1. bootloader/t186ref/tegra194-a02-bpmp-p3668-a00.dtb
  2. kernel/dtb/tegra194-p3668-all-p3509-0000.dtb
  3. bootloader/t186ref/BCT/tegra194-mb1-bct-misc-l4t.cfg
  4. bootloader/t186ref/BCT/tegra194-mb1-bct-misc-flash.cfg
  5. p3668.conf.common

please disassembler the dtb file into text file for modification, $ dtc -I dtb -O dts -o temp.dts tegra194-p3668-all-p3509-0000.dtb
after that, you could convert the DTS into a new DTB file, $ dtc -I dts -O dtb -o output.dtb temp.dts
thanks
