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 kernel to NAND flash
|

|
|
|
|
|
|
|
|
=> tftp $loadaddr uImage
|
|
|
|
|
=> nand erase 0x100000 0x1e0000
|
|
|
|
|
=> nand write $loadaddr 0x100000 0x1e0000

2. Program the DTB to NAND flash
|
2013-04-19 11:13:08 +02:00
|
|
|
|
|
|
|
|
=> tftp $loadaddr mpc8315erdb.dtb
|
|
|
|
|
=> nand erase 0x2e0000 0x20000
|
|
|
|
|
=> nand write $loadaddr 0x2e0000 0x20000
|

3. Program the root filesystem to NAND flash
|
2013-04-19 11:13:08 +02:00
|
|
|
|
|
|
|
|
=> tftp $loadaddr rootfs.jffs2
|
|
|
|
|
=> nand erase 0x400000 0x1c00000
|
|
|
|
|
=> nand write $loadaddr 0x400000 $filesize

4. Booting your new system
|
2013-04-19 11:13:08 +02:00
|
|
|
|
|
|
|
|
=> setenv nandboot 'setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=$consoledev,$baudrate;nand read $fdtaddr 0x2e0000 0x20000;nand read $loadaddr 0x100000 0x1e0000;bootm $loadaddr - $fdtaddr'
|
|
|
|
|
|
|
|
|
|
If you want to set this boot option as default:
|
|
|
|
|
|
|
|
|
|
=> setenv bootcmd 'run nandboot'
|
|
|
|
|
=> saveenv
|
|
|
|
|
|
|
|
|
|
...or for a single boot:
|
|
|
|
|
|
|
|
|
|
=> run nandboot
|
|
|
|
|
|
|
|
|
|
You can login with user "root".
