1 You'll need to program the files created by buildroot into the flash.
2 The fast way is to tftp transfer the files via one of the network interfaces.
4 Alternatively you can transfer the files via serial console with an Ymodem
5 file transfer from your terminal program by using a "loady" command
6 from the u-boot prompt instead of the "tftp ..." commands stated below.
7 Beware that serial console file transfers are quite slow!
9 1. Program the DTB to NOR flash
11 => tftp ${loadaddr} p2020ds.dtb
12 => erase 0xeff00000 0xeff7ffff
13 => cp.b ${loadaddr} 0xeff00000 ${filesize}
15 2. Program the kernel to NOR flash
17 => tftp ${loadaddr} uImage
18 => erase 0xec000000 0xec3fffff
19 => cp.b ${loadaddr} 0xec000000 ${filesize}
21 3. Program the root filesystem to NOR flash
23 => tftp ${loadaddr} rootfs.jffs2
24 => erase 0xec400000 0xeeffffff
25 => cp.b ${loadaddr} 0xec400000 ${filesize}
27 4. Booting your new system
29 => setenv jffs2boot 'setenv bootargs root=/dev/mtdblock4 rootfstype=jffs2 rw console=ttyS0,115200;bootm ec000000 - eff00000'
31 If you want to set this boot option as default:
33 => setenv bootcmd 'run jffs2boot'
36 ...or for a single boot:
40 You can login with user "root".
