72Burn U-Boot images to NAND
73--------------------------
74
Masahiro Yamadad085ecd2016-03-23 01:40:05 +090075Write the following to the NAND device:
76
Masahiro Yamada3cb9abc2016-02-02 12:53:31 +090077 - spl/u-boot-spl.bin at the offset address 0x00000000
Masahiro Yamadacf3175b2017-01-30 13:12:28 +090078 - u-boot.bin at the offset address 0x00020000

80or
81
82 - u-boot-with-spl.bin at the offset address 0x00000000
Masahiro Yamada7168da12015-02-05 14:30:23 +090083
84If a TFTP server is available, the images can be easily updated.
Masahiro Yamadad085ecd2016-03-23 01:40:05 +090085Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
Masahiro Yamada95a2d432016-03-23 01:40:03 +090086and then run the following command at the U-Boot command line:
Masahiro Yamada7168da12015-02-05 14:30:23 +090087
88 => run nandupdate

Masahiro Yamadac231c432016-02-16 17:08:41 +090091Burn U-Boot images to eMMC
92--------------------------
93
Masahiro Yamadad085ecd2016-03-23 01:40:05 +090094Write the following to the Boot partition 1 of the eMMC device:
95
Masahiro Yamadac231c432016-02-16 17:08:41 +090096 - spl/u-boot-spl.bin at the offset address 0x00000000

Masahiro Yamadac231c432016-02-16 17:08:41 +0900102
103If a TFTP server is available, the images can be easily updated.
Masahiro Yamadad085ecd2016-03-23 01:40:05 +0900104Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
Masahiro Yamada95a2d432016-03-23 01:40:03 +0900105and then run the following command at the U-Boot command line:
Masahiro Yamadac231c432016-02-16 17:08:41 +0900106
107 => run emmcupdate

175Set BSKZ[1:0] to 0b01 for U-Boot.
176This mode is the most handy because EA[24] is always supported by the save pin
177mode of the system bus. On the other hand, EA[25] is not supported for some
178newer SoCs. Even if it is, EA[25] is not connected on most of the boards.
