| Arcturus uCP1020 SoM |
| ==================== |
| |
| This tutorial describes how to use the predefined Buildroot |
| configuration for the Arcturus uCP1020 SoM platform. |
| |
| Additional information about this module can be found at |

| |
| Building |
| -------- |
| |
| make arcturus_ucp1020_defconfig |
| make |
| |
| Result of the build |
| ------------------- |
| |
| After building, you should obtain this tree: |
| |
| output/images/ |
| +-- rootfs.jffs2 |
| +-- rootfs.tar |
| +-- u-boot.bin |
| +-- ucp1020.dtb |
| +-- uImage |
| |
| Flashing |
| -------- |
| |
| You'll need to program the files created by buildroot into the NOR flash. |
| |
| 1. Program the new U-Boot binary (optional) |
| If you don't feel confident upgrading your bootloader then don't do it, |
| it's unnecessary most of the time. |
| |
| B$ tftp u-boot.bin |
| B$ protect off 0xeff80000 +$filesize |
| B$ erase 0xeff80000 +$filesize |
| B$ cp.b $loadaddr 0xeff80000 $filesize |
| B$ protect on 0xeff80000 +$filesize |
| |
| 2. Program the kernel |
| |
| B$ tftp uImage |
| B$ erase 0xec140000 +$filesize |
| B$ cp.b $loadaddr 0xec140000 $filesize |
| |
| 3. Program the DTB |
| |
| B$ tftp ucp1020.dtb |
| B$ erase 0xec100000 +$filesize |
| B$ cp.b $loadaddr 0xec100000 $filesize |
| |
| 4. Program the jffs2 root filesystem |
| |
| B$ tftp rootfs.jffs2 |
| B$ erase 0xec800000 0xee8fffff |
| B$ cp.b $loadaddr 0xec800000 $filesize |
| |
| 5. Booting your new system |
| |
| B$ setenv norboot 'setenv bootargs root=/dev/mtdblock1 rootfstype=jffs2 console=$consoledev,$baudrate;bootm 0xec140000 - 0xec100000' |
| |
| If you want to set this boot option as default: |
| |
| B$ setenv bootcmd 'run norboot' |
| B$ saveenv |
| |
| ...or for a single boot: |
| |
| B$ run norboot |
| |
| Good Luck ! |
