8 (a) Ubuntu packages (CROSS_COMPILE=arm-linux-gnueabi-)
9
10 If you are building U-Boot on Ubuntu, its standard package is recommended.
11 You can install it as follows:
12
13 $ sudo apt-get install gcc-arm-linux-gnueabi-
14
15 (b) Linaro compilers (CROSS_COMPILE=arm-linux-gnueabihf-)

63Burn U-Boot images to NAND
64--------------------------
65
66Write two files to the NAND device as follows:
Masahiro Yamadaf4e190e2015-08-28 20:13:18 +090067 - spl/u-boot-spl-dtb.bin at the offset address 0x00000000
68 - u-boot-dtb.img at the offset address 0x00010000
Masahiro Yamada7168da12015-02-05 14:30:23 +090069
70If a TFTP server is available, the images can be easily updated.
Masahiro Yamadaf4e190e2015-08-28 20:13:18 +090071Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
72directory, and then run the following command at the U-Boot command line:
Masahiro Yamada7168da12015-02-05 14:30:23 +090073
74 => run nandupdate
75

124 bit 7 ----> BURST_EN
125 bit 8 ----> FLASHBUS32_16
126
127The BKSZ[1:0] specifies the address range of memory slot and peripherals
128as follows:

137Set BSKZ[1:0] to 0b01 for U-Boot.
138This mode is the most handy because EA[24] is always supported by the save pin
139mode of the system bus. On the other hand, EA[25] is not supported for some
140newer SoCs. Even if it is, EA[25] is not connected on most of the boards.
