Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
Armadeus APFxx are Systems On Module (SOM) based on Freescale/NXP i.MX
|
||
|
|
processors associated with an FPGA (except on APF28). Non volatile
|
||
|
|
data are stored in on-module NOR or NAND Flash, depending on the
|
||
|
|
model. These SOM can be used on Armadeus development boards or with
|
||
|
|
custom docking boards.
|
||
|
|
|
||
|
|
Supported platforms
|
||
|
|
===================
|
||
|
|
|
||
|
|
Buildroot currently supports the following Armadeus platforms with the
|
||
|
|
associated defconfigs:
|
||
|
|
|
||
|
|
* APF9328 SOM + devt boards -> armadeus_apf9328_defconfig
|
||
|
|
* APF27 SOM + devt board -> armadeus_apf27_defconfig
|
||
|
|
* APF51 SOM + devt board -> armadeus_apf51_defconfig
|
||
|
|
* APF28 SOM + devt board -> armadeus_apf28_defconfig
|
||
|
|
|
||
|
|
Vanilla Linux versions are preferred to Freescale's one in these
|
||
|
|
configurations.
|
||
|
|
|
||
|
|
How to build it
|
||
|
|
===============
|
||
|
|
|
||
|
|
Configure Buildroot
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
Let's say you own an APFxx SOM with it's corresponding development
|
||
|
|
board, all you have to do is:
|
||
|
|
|
||
|
|
$ make armadeus_apfxx_defconfig
|
||
|
|
|
||
|
|
where "apfxx" is the version of your SOM.
|
||
|
|
|
||
|
|
Launch build
|
||
|
|
------------
|
||
|
|
|
||
|
|
$ make
|
||
|
|
|
||
|
|
Result of the build
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
When the build is finished, you will end up with:
|
||
|
|
|
||
|
|
output/images/
|
||
|
|
├── imx**-apfxxdev.dtb [1]
|
||
|
|
├── rootfs.jffs2 [2]
|
||
|
|
├── rootfs.tar
|
||
|
|
├── rootfs.ubi [2]
|
||
|
|
├── rootfs.ubifs [2]
|
||
|
|
└── uImage
|
||
|
|
|
||
|
|
[1] Only if the kernel version used uses a Device Tree.
|
||
|
|
[2] .ubi/.ubifs images are not available on APF9328 and replaced by a
|
||
|
|
.jffs2 one in this case.
|
||
|
|
|
||
|
|
Building U-Boot is currently not supported in these configurations.
|
||
|
|
|
||
|
|
Installation
|
||
|
|
============
|
||
|
|
|
||
|
|
You will require a serial connection to the board and a TFTP server on
|
||
|
|
your Host PC. Assuming your server is configured for exporting
|
||
|
|
/tftpboot/ directory, you will have to copy the generated images to
|
||
|
|
it:
|
||
|
|
|
||
|
|
$ cp output/images/uImage /tftpboot/apfxx-linux.bin
|
||
|
|
$ cp output/images/*.dtb /tftpboot/
|
||
|
|
$ cp output/images/rootfs.ubi /tftpboot/apfxx-rootfs.ubi
|
||
|
|
$ cp output/images/rootfs.jffs2 /tftpboot/apfxx-rootfs.jffs2
|
||
|
|
|
||
|
|
where "apfxx" is the version of your SOM, as used with _defconfigs.
|
||
|
|
|
||
|
|
Then on your serial terminal, all you have to do is:
|
||
|
|
|
||
|
|
* interrupt the boot process and access U-Boot console by pressing any
|
||
|
|
key when booting,
|
||
|
|
* configure board and server IP addresses with "ipaddr" and "serverip"
|
||
|
|
environment variables,
|
||
|
|
* if you want to update kernel:
|
||
|
|
BIOS > run update_kernel
|
||
|
|
* if you want to update device tree:
|
||
|
|
BIOS > run update_dtb
|
||
|
|
* if you want to update rootfs:
|
||
|
|
BIOS > run update_rootfs
|
||
|
|
|
||
|
|
That's it !
