U-boot for Odroid X2/U3 |
||||
======================== |
||||
|
||||
1. Summary |
||||
========== |
||||
This is a quick instruction for setup Odroid boards based on Exynos4412. |
||||
Board config: odroid_config |
||||
|
||||
2. Supported devices |
||||
==================== |
||||
This U-BOOT config can be used on two boards: |
||||
- Odroid U3 |
||||
- Odroid X2 |
||||
with CPU Exynos 4412 rev 2.0 and 2GB of RAM |
||||
|
||||
3. Boot sequence |
||||
================ |
||||
iROM->BL1->(BL2 + TrustZone)->U-BOOT |
||||
|
||||
This version of U-BOOT doesn't implement SPL but it is required(BL2) |
||||
and can be found in "boot.tar.gz" from here: |
||||
http://dev.odroid.com/projects/4412boot/wiki/FrontPage?action=download&value=boot.tar.gz |
||||
or here: |
||||
http://odroid.in/guides/ubuntu-lfs/boot.tar.gz |
||||
|
||||
4. Boot media layout |
||||
==================== |
||||
The table below shows SD/eMMC cards layout for U-boot. |
||||
The block offset is starting from 0 and the block size is 512B. |
||||
------------------------------------- |
||||
| Binary | Block offset| part type | |
||||
| name | SD | eMMC |(eMMC only)| |
||||
------------------------------------- |
||||
| Bl1 | 1 | 0 | 1 (boot) | |
||||
| Bl2 | 31 | 30 | 1 (boot) | |
||||
| U-boot | 63 | 62 | 1 (boot) | |
||||
| Tzsw | 2111 | 2110 | 1 (boot) | |
||||
| Uboot Env | 2500 | 2500 | 0 (user) | |
||||
------------------------------------- |
||||
|
||||
5. Prepare the SD boot card - with SD card reader |
||||
================================================= |
||||
To prepare bootable media you need boot binaries provided by hardkernel. |
||||
File "boot.tar.gz" (link in point 3.) contains: |
||||
- E4412_S.bl1.HardKernel.bin |
||||
- E4412_S.tzsw.signed.bin |
||||
- bl2.signed.bin |
||||
- sd_fusing.sh |
||||
- u-boot.bin |
||||
|
||||
This is all you need to boot this board. But if you want to use your custom |
||||
u-boot then you need to change u-boot.bin with your own u-boot binary* |
||||
and run the script "sd_fusing.sh" - this script is valid only for SD card. |
||||
|
||||
*note: |
||||
The proper binary file of current U-boot is u-boot-dtb.bin. |
||||
|
||||
quick steps for Linux: |
||||
- extract boot.tar.gz |
||||
- 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) |
||||
Check if Hardkernel U-boot is booting, and next do the same with your U-boot. |
||||
|
||||
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 |
||||
which supports eMMC partiion switch. All of the boot binaries are stored |
||||
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. |
||||
|
||||
8. Prepare the boot media using Hardkernel U-boot |
||||
================================================= |
||||
You can update the U-boot to the custom one if you have an working bootloader |
||||
delivered with the board on a eMMC/SD card. Then follow the steps: |
||||
- install the android fastboot tool |
||||
- connect a micro usb cable to the board |
||||
- on the U-boot prompt, run command: fastboot (as a root) |
||||
- on the host, run command: "fastboot flash bootloader u-boot-dtb.bin" |
||||
- the custom U-boot should start after the board resets. |
||||
|
||||
9. Partition layout |
||||
==================== |
||||
Default U-boot environment is setup for fixed partiion layout. |
||||
|
||||
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 |
||||
|
||||
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 |
