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 !
