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