Write two files to the NAND device as follows:
|
||||
- spl/u-boot-spl-dtb.bin at the offset address 0x00000000
|
||||
- u-boot-dtb.img at the offset address 0x00010000
|
||||
- spl/u-boot-spl.bin at the offset address 0x00000000
|
||||
- u-boot.img at the offset address 0x00010000
|
||||
|
||||
If a TFTP server is available, the images can be easily updated.
|
||||
Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
