Masahiro Yamada7168da12015-02-05 14:30:23 +0900[diff] [blame]63You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-"
64to use your favorite compiler.

67Burn U-Boot images to NAND
68--------------------------
69
70Write two files to the NAND device as follows:
Masahiro Yamadaf4e190e2015-08-28 20:13:18 +0900[diff] [blame]71 - spl/u-boot-spl-dtb.bin at the offset address 0x00000000
72 - u-boot-dtb.img at the offset address 0x00010000
Masahiro Yamada7168da12015-02-05 14:30:23 +0900[diff] [blame]73
74If a TFTP server is available, the images can be easily updated.
Masahiro Yamadaf4e190e2015-08-28 20:13:18 +0900[diff] [blame]75Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
76directory, and then run the following command at the U-Boot command line:
Masahiro Yamada7168da12015-02-05 14:30:23 +0900[diff] [blame]77
78 => run nandupdate

141Set BSKZ[1:0] to 0b01 for U-Boot.
142This mode is the most handy because EA[24] is always supported by the save pin
143mode of the system bus. On the other hand, EA[25] is not supported for some
144newer SoCs. Even if it is, EA[25] is not connected on most of the boards.
