16Result of the build
17-------------------
18
19After building, you should obtain this tree:
20
21 output/images/
22 +-- rootfs.jffs2
23 +-- rootfs.tar
24 +-- u-boot.bin
25 +-- ucp1020.dtb
26 +-- uImage
27
28Flashing
29--------
30
31You'll need to program the files created by buildroot into the NOR flash.
32
331. Program the new U-Boot binary (optional)
34 If you don't feel confident upgrading your bootloader then don't do it,
35 it's unnecessary most of the time.
36
37 B$ tftp u-boot.bin
38 B$ protect off 0xeff80000 +$filesize
39 B$ erase 0xeff80000 +$filesize
40 B$ cp.b $loadaddr 0xeff80000 $filesize
41 B$ protect on 0xeff80000 +$filesize
42
432. Program the kernel
44
45 B$ tftp uImage
46 B$ erase 0xec140000 +$filesize
47 B$ cp.b $loadaddr 0xec140000 $filesize
48
493. Program the DTB
50
51 B$ tftp ucp1020.dtb
52 B$ erase 0xec100000 +$filesize
53 B$ cp.b $loadaddr 0xec100000 $filesize
54
554. Program the jffs2 root filesystem
56
57 B$ tftp rootfs.jffs2
58 B$ erase 0xec800000 0xee8fffff
59 B$ cp.b $loadaddr 0xec800000 $filesize
60
615. Booting your new system
62
63 B$ setenv norboot 'setenv bootargs root=/dev/mtdblock1 rootfstype=jffs2 console=$consoledev,$baudrate;bootm 0xec140000 - 0xec100000'
64
65 If you want to set this boot option as default:
66
67 B$ setenv bootcmd 'run norboot'
68 B$ saveenv
69
70 ...or for a single boot:
71
72 B$ run norboot
73
74Good Luck !
