spl/u-boot-spl.bin at the offset address 0x00000000 80 - u-boot.img at the offset address 0x00010000 81 82If a TFTP server is available, the images can be easily updated. 83Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public 84directory, and then run the following command at the U-Boot command line: 85 86 => run nandupdate 87 88 89Burn U-Boot images to eMMC 90-------------------------- 91 92Write two files to the Boot partition 1 of the eMMC device as follows: 93 - spl/u-boot-spl.bin at the offset address 0x00000000 94 - u-boot.img at the offset address 0x00010000 95 96If a TFTP server is available, the images can be easily updated. 97Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public 98directory, and then run the following command at the U-Boot command line: 99 100 => run emmcupdate 101 102 103UniPhier specific commands 104-------------------------- 105 106 -

On the other hand, EA[25] is not supported for some 168newer SoCs. Even if it is, EA[25] is not connected on most of the boards. 169 170-- 171Masahiro Yamada <yamada.masahiro@socionext.com> 172Feb. 2016 173
