| 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 |
| |
| => tftp $loadaddr mpc8315erdb.dtb |
| => nand erase 0x2e0000 0x20000 |
| => nand write $loadaddr 0x2e0000 0x20000 |
| |
| 3. Program the root filesystem to NAND flash |
| |
| => tftp $loadaddr rootfs.jffs2 |
| => nand erase 0x400000 0x1c00000 |
| => nand write $loadaddr 0x400000 $filesize |
| |
| 4. Booting your new system |
| |
| => setenv nandboot 'setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=$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". |
