  1. For the bootloader, NXP has stablized at SDK2.0 (final release). It is
  2. suggested to download the prebuilt from NXP downloads and follow the
  3. release notes for reflashing.
  4. To program the kernel and rootfs created by buildroot into the flash. The
  5. fast way is to tftp transfer the files via one of the network interfaces.
  6. Make sure your devkit has ipaddr, netmask, and serverip defined to reach your
  7. tftp server. Verify bootargs are reasonable (console=ttyS0,115200).
  8. ------------------------------------------------------------------------------
  9. Devkit: T1040RDB
  10. (Assuming the default u-boot env from NXP)
  11. 1. Program the DTB to NOR flash
  12. => tftpboot $loadaddr t1040d4rdb.dtb; protect off 0xe8800000 +$filesize; erase 0xe8800000 +$filesize; cp.b $loadaddr 0xe8800000 $filesize; protect on 0xe8800000 +$filesize; cmp.b $loadaddr 0xe8800000 $filesize
  13. 2. Program the kernel and rootfs to NOR flash
  14. => tftpboot $loadaddr uImage; protect off 0xe8020000 +$filesize; erase 0xe8020000 +$filesize; cp.b $loadaddr 0xe8020000 $filesize; protect on 0xe8020000 +$filesize; cmp.b $loadaddr 0xe8020000 $filesize
  15. => tftpboot $loadaddr rootfs.cpio.uboot; protect off 0xe9300000 +$filesize; erase 0xe9300000 +$filesize; cp.b $loadaddr 0xe9300000 $filesize; protect on 0xe9300000 +$filesize; cmp.b $loadaddr 0xe9300000 $filesize
  16. 3. Booting your new system
  17. => boot
  18. You can login with user "root".
  19. ------------------------------------------------------------------------------
  20. Devkit: T2080 QDS or RDB
  21. (Assuming the default u-boot env from NXP)
  22. 1. Netboot the kernel/rootfs/dtb
  23. => tftp 0x1000000 uImage && tftp 0x2000000 rootfs.cpio.uboot
  24. RDB => tftp 0x3000000 t2080rdb.dtb
  25. or
  26. QDS => tftp 0x3000000 t2080qds.dtb
  27. 2. Booting your new system
  28. => bootm 0x1000000 0x2000000 0x3000000
  29. You can login with user "root".
  30. 3. If flashing is desired, a similar approach to the T1040 can be followed
  31. with updated addresses for the flash layout. Example is in the NXP default
  32. env.
