  53 +setenv scriptaddr 0x88100000; setenv script_offset_f 0x1fff000; setenv script_size_f 0x1000;
  54 +setenv kernel_addr_r 0x84000000; setenv kernel_comp_addr_r 0x90000000; setenv kernel_comp_size 0x10000000;
  55 +setenv fdt_addr_r 0x88000000; setenv ramdisk_addr_r 0x88300000;
  56 +```
  57 +2. Set IP addresses for the board and your tftp server

  66 +4. Load and boot the kernel
  67 +```
  68 +booti ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r};
