Hi kassey,

Please following below steps:

  1. Create /etc/xinetd.d/tftp
  2. Create tftpboot folder:
    $ mkdir /home/[username]/tftpboot
  3. Copy boot.img and dtb file: (Please use encrypt files)
    $ cp boot_sigheader.img.encrypt /home/[username]/tftpboot/boot.img
    $ cp *.dtb.encrypt /home/[username]/tftpboot/jetson.dtb
  4. Change boot-order and tftp-server ip with cbo.dts
  5. Flash:
    $ sudo ./flash -r jetson-tx2 mmcblk0p1
  • Using below command to generate the encrypt signed file:

$sudo ./flash.sh --no-flash -k kernel jetson-tx2 mmcblk0p1
$sudo ./flash.sh --no-flash -k kernel-dtb tx2 mmcblk0p1
