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
<www.arcturusnetworks.com/products/ucp1020>
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 $filesize
2. Program the kernel
B$ 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 !
