|
|
|
|
====================
|
2014-12-12 05:45:46 +00:00
|
|
|
This U-BOOT config can be used on three boards:
|
2014-09-01 11:50:53 +00:00
|
|
|
- Odroid U3
|
|
|
|
|

|
|
|
|
with CPU Exynos 4412 rev 2.0 and 2GB of RAM
|
2014-12-12 05:45:46 +00:00
|
|
|
- Odroid XU3
|
2016-04-08 03:06:42 +00:00
|
|
|
- Odroid XU4
|
2018-11-12 10:32:43 +00:00
|
|
|

3. Boot sequence
|
|
|
|
|
================
|
|
|
|
|
iROM->BL1->(BL2 + TrustZone)->U-BOOT
|
|
|
|
|
|
2014-12-12 05:45:46 +00:00
|
|
|
This version of U-BOOT doesn't implement SPL. So, BL1, BL2, and TrustZone
|
|
|
|
|
binaries are needed to boot up.

4. Boot media layout
|
|
|
|
|
====================
|
2016-02-06 03:30:11 +00:00
|
|
|
The table below shows SD/eMMC cards layout for U-Boot.
|
2014-09-01 11:50:53 +00:00
|
|
|
The block offset is starting from 0 and the block size is 512B.
|
|
|
|
|
-------------------------------------
|

|
5. Prepare the SD boot card - with SD card reader
|
|
|
|
|
=================================================
|
|
|
|
|
To prepare bootable media you need boot binaries provided by hardkernel.
|
2014-12-12 05:45:46 +00:00
|
|
|
From the downloaded files, You can find:
|
|
|
|
|
- bl1.bin
|
|
|
|
|
- tzsw.bin
|
|
|
|
|
- bl2.bin
|
2014-09-01 11:50:53 +00:00
|
|
|
- sd_fusing.sh
|
|
|
|
|
- u-boot.bin
|
2014-12-12 05:45:46 +00:00
|
|
|
(The file names can be slightly different, but you can distinguish what they are
|
|
|
|
|
without problem)
|
2014-09-01 11:50:53 +00:00
|
|
|
|
|
|
|
|
This is all you need to boot this board. But if you want to use your custom
|
2016-02-06 03:30:11 +00:00
|
|
|
U-Boot then you need to change u-boot.bin with your own U-Boot binary*
|
2014-09-01 11:50:53 +00:00
|
|
|
and run the script "sd_fusing.sh" - this script is valid only for SD card.
|
|
|
|
|
|
|
|
|
|
*note:
|
2016-02-06 03:30:11 +00:00
|
|
|
The proper binary file of current U-Boot is u-boot-dtb.bin.
|
2014-09-01 11:50:53 +00:00
|
|
|
|
|
|
|
|
quick steps for Linux:
|
2014-12-12 05:45:46 +00:00
|
|
|
- Download all files from the link at point 3 and extract it if needed.
|
2014-09-01 11:50:53 +00:00
|
|
|
- put any SD card into the SD reader
|
|
|
|
|
- check the device with "dmesg"
|
|
|
|
|
- run ./sd_fusing.sh /dev/sdX - where X is SD card device (but not a partition)
|
2016-02-06 03:30:11 +00:00
|
|
|
Check if Hardkernel U-Boot is booting, and next do the same with your U-Boot.
|
2014-09-01 11:50:53 +00:00
|
|
|
|
|
|
|
|
6. Prepare the eMMC boot card
|
|
|
|
|
with a eMMC card reader (boot from eMMC card slot)
|
|
|
|
|
=====================================================
|
|
|
|
|
To boot the device from the eMMC slot you should use a special card reader
|
2014-12-12 05:45:46 +00:00
|
|
|
which supports eMMC partition switch. All of the boot binaries are stored
|
2014-09-01 11:50:53 +00:00
|
|
|
on the eMMC boot partition which is normally hidden.
|
|
|
|
|
|
|
|
|
|
The "sd_fusing.sh" script can be used after updating offsets of binaries
|
|
|
|
|
according to the table from point 4. Be sure that you are working on the right
|
|
|
|
|
eMMC partition - its size is usually very small, about 1-4 MiB.
|
|
|
|
|
|
|
|
|
|
7. Prepare the eMMC boot card
|
|
|
|
|
with a SD card reader (boot from SD card slot)
|
|
|
|
|
=================================================
|
|
|
|
|
If you have an eMMC->microSD adapter you can prepare the card as in point 5.
|
|
|
|
|
But then the device can boot only from the SD card slot.
|
|
|
|
|
|
2016-02-06 03:30:11 +00:00
|
|
|
8. Prepare the boot media using Hardkernel U-Boot
|
2014-09-01 11:50:53 +00:00
|
|
|
=================================================
|
2016-02-06 03:30:11 +00:00
|
|
|
You can update the U-Boot to the custom one if you have a working bootloader
|
2014-12-12 05:45:46 +00:00
|
|
|
delivered with the board on the eMMC/SD card. Then follow the steps:
|
2014-09-01 11:50:53 +00:00
|
|
|
- install the android fastboot tool
|
|
|
|
|
- connect a micro usb cable to the board
|
2016-02-06 03:30:11 +00:00
|
|
|
- on the U-Boot prompt, run command: fastboot (as a root)
|
2014-09-01 11:50:53 +00:00
|
|
|
- on the host, run command: "fastboot flash bootloader u-boot-dtb.bin"
|
2016-02-06 03:30:11 +00:00
|
|
|
- the custom U-Boot should start after the board resets.
|
2014-09-01 11:50:53 +00:00
|
|
|
|
|
|
|
|
9. Partition layout
|
|
|
|
|
====================
|
2016-02-06 03:30:11 +00:00
|
|
|
Default U-Boot environment is setup for fixed partition layout.
|
2014-09-01 11:50:53 +00:00
|
|
|
|
|
|
|
|
Partition table: MSDOS. Disk layout and files as listed in the table below.
|
|
|
|
|
----- ------ ------ ------ -------- ---------------------------------
|
|
|
|
|
| Num | Name | FS | Size | Offset | Reguired files |
|
|
|
|
|
| | | Type | MiB | MiB | |
|
|
|
|
|
----- ------ ------ ------ -------- ---------------------------------
|
|
|
|
|
| 1 | BOOT | fat | 100 | 2 | kernel, fdt** |
|
|
|
|
|
| 2 | ROOT | ext4 | - | | any Linux system |
|
|
|
|
|
----- ------ ------ ------ -------- ---------------------------------
|
|
|
|
|
|
|
|
|
|
**note:
|
|
|
|
|
Supported fdt files are:
|
|
|
|
|
- exynos4412-odroidx2.dtb
|
|
|
|
|
- exynos4412-odroidu3.dtb
|
2014-12-12 05:45:46 +00:00
|
|
|
- exynos5422-odroidxu3.dtb
|
2018-11-12 10:32:43 +00:00
|
|
|
- exynos5422-odroidxu3-lite.dtb
|
2016-04-08 03:06:42 +00:00
|
|
|
- exynos5422-odroidxu4.dtb
|
2018-11-12 10:32:43 +00:00
|
|
|
- exynos5422-odroidhc1.dtb
|
2014-09-01 11:50:53 +00:00
|
|
|
|
|
|
|
|
Supported kernel files are:
|
|
|
|
|
- Image.itb
|
|
|
|
|
- zImage
|
|
|
|
|
- uImage
|
|
|
|
|
|
|
|
|
|
The default environmental variable "dfu_alt_info" is set* for above layout.
|
|
|
|
|
Each partition size is just an example, dfu_alt_info tries init two partitions.
|
|
|
|
|
The size of each is not important.
|
|
|
|
|
|
|
|
|
|
*note:
|
|
|
|
|
$dfu_alt_info is set on a boot time and it is concatenated using two variables:
|
|
|
|
|
- $dfu_alt_boot(set dynamically)
|
|
|
|
|
- $dfu_alt_system(from current env).
|
|
|
|
|
|
|
|
|
|
To add any changes to dfu_alt_info - please modify $dfu_alt_system only.
|
|
|
|
|
Changes are visible after board reset.
|
|
|
|
|
|
|
|
|
|
10. The environment and booting the kernel
|
|
|
|
|
==========================================
|
|
|
|
|
There are three macros defined in config for various boot options:
|
|
|
|
|
Two for both, kernel with device tree support and also without it:
|
|
|
|
|
- boot_uimg - load uImage
|
|
|
|
|
- boot_zimg - load zImage
|
|
|
|
|
If proper fdt file exists then it will be automatically loaded,
|
|
|
|
|
so for old kernel types, please remove fdt file from boot partition.
|
|
|
|
|
|
|
|
|
|
The third boot option for multi image support (more info: doc/uImage.FIT/)
|
|
|
|
|
- boot_fit - for binary file: "Image.itb"
|
|
|
|
|
|
|
|
|
|
Default boot command: "autoboot"
|
|
|
|
|
And the boot sequence is:
|
|
|
|
|
- boot_fit - if "Image.itb" exists
|
|
|
|
|
- boot_zimg - if "zImage" exists
|
|
|
|
|
- boot_uimg - if "uImage" exists
|

|
11. USB host support
|
|
|
|
|
====================
|
2014-12-12 05:45:46 +00:00
|
|
|
NOTE: This section is only for Odroid X2/U3.
|
2014-11-21 01:26:29 +00:00
|
|
|
|
|
|
|
|
The ethernet can be accessed after starting the USB subsystem in U-Boot.
|
|
|
|
|
The adapter does not come with a preconfigured MAC address, and hence it needs
|
|
|
|
|
to be set before starting USB.
|
|
|
|
|
setenv usbethaddr 02:DE:AD:BE:EF:FF
|
|
|
|
|
|
|
|
|
|
Note that in this example a locally managed MAC address is chosen. Care should
|
|
|
|
|
be taken to make these MAC addresses unique within the same subnet.
|
|
|
|
|
|
|
|
|
|
Start the USB subsystem:
|
|
|
|
|
Odroid # setenv usbethaddr 02:DE:AD:BE:EF:FF
|
|
|
|
|
Odroid # usb start
|
|
|
|
|
(Re)start USB...
|
|
|
|
|
USB0: USB EHCI 1.00
|
|
|
|
|
scanning bus 0 for devices... 4 USB Device(s) found
|
|
|
|
|
scanning usb for storage devices... 1 Storage Device(s) found
|
|
|
|
|
scanning usb for ethernet devices... 1 Ethernet Device(s) found
|
|
|

|
|
|
|
Automatic IP assignment:
|
|
|
|
|
------------------------
|
|
|
|
|
If the ethernet is connected to a DHCP server (router maybe with DHCP enabled),
|
|
|
|
|
then the below will automatically assign an ip address through DHCP.
|
|
|
|
|
setenv autoload no
|
|
|
|
|
dhcp
|
|
|
|
|
|
|
|
|
|
Odroid # setenv autoload no
|
|
|
|
|
Odroid # dhcp
|
|
|
|
|
Waiting for Ethernet connection... done.

|
|
|
|
|
Odroid #
|
|
|
|
|
|
|
|
|
|
Note that this automatically sets the many IP address related variables in
|
|
|
|
|
U-Boot that is obtained from the DHCP server.
|
|
|
|
|
|
|
|
|
|
Odroid # printenv ipaddr netmask gatewayip dnsip
|
|
|
|
|
ipaddr=192.168.1.10
|
|
|
|
|
netmask=255.255.255.0
|
|
|
|
|
gatewayip=192.168.1.1
|
|
|
|
|
dnsip=192.168.1.1
|
|
|
|
|

|
|
|
Ping example:
|
|
|
|
|
The ping command can be used a test to check connectivity. In this example,
|
|
|
|
|
192.168.1.27 is a pingable server in the network.
|
|
|
|
|
Odroid # ping 192.168.1.27
|
|
|
|
|
Waiting for Ethernet connection... done.

|
Static IP assignment:
|
|
|
|
|
---------------------
|
|
|
|
|
In the case where there are no DHCP servers in the network, or you want to
|
|
|
|
|
set the IP address statically, it can be done by:
|
|
|
|
|
Odroid # setenv ipaddr 192.168.1.10
|
|
|
|
|
Odroid # ping 192.168.1.27
|
|
|
|
|
Waiting for Ethernet connection... done.
|
|
|
|
|
Using sms0 device
|
|
|
|

|
|
|
|
|
|
|
|
|
TFTP booting:
|
|
|
|
|
-------------
|
|
|
|
|
Say there exists a tftp server in the network with address 192.168.1.27 and
|
|
|
|
|
it serves a kernel image (zImage.3.17) and a DTB blob (exynos4412-odroidu3.dtb)
|
|
|
|
|
that needs to be loaded and booted. It can be accomplished as below:
|
|
|
|
|
(Assumes that you have setenv usbethaddr, and have not set autoload to no)
|
|
|
|
|
|
|
|
|
|
Odroid # setenv serverip 192.168.1.27
|
|
|
|
|
Odroid # tftpboot 0x40080000 zImage.3.17
|
|
|
|
|
Waiting for Ethernet connection... done.
|
|
|
|
|

USB Storage booting:
|
|
|
|
|
--------------------
|
|
|
|
|
Similarly we can use the USB storage to load the kernel image/initrd/fdt etc
|
|
|
|
|
and boot. For this example, there is a USB drive plugged in. It has a FAT
|
|
|
|
|
1st partition and an EXT 2nd partition. Using the generic FS (ls/load) makes
|
|
|
|
|
it even easier to work with FAT/EXT file systems.
|
|
|
|
|
For this example the second EXT partition is used for booting and as rootfs.
|
|
|
|
|
The boot files - kernel and the dtb are present in the /boot directory of the
|
|
|
|
|
second partition.
