4. Boot media layout
====================
-The table below shows SD/eMMC cards layout for U-boot.
+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 |
-------------------------------------
| Bl1 | 1 | 0 | 1 (boot) |
| Bl2 | 31 | 30 | 1 (boot) |
-| U-boot | 63 | 62 | 1 (boot) |
+| U-Boot | 63 | 62 | 1 (boot) |

+| Uboot Env | 2560 | 2560 | 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
+From the downloaded files, You can find:
+- bl1.bin
+- tzsw.bin
+- bl2.bin
- sd_fusing.sh
- u-boot.bin
+(The file names can be slightly different, but you can distinguish what they are
+without problem)
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*
+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.
+The proper binary file of current U-Boot is u-boot-dtb.bin.
quick steps for Linux:
-- extract boot.tar.gz
+- Download all files from the link at point 3 and extract it if needed.
- 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
+which supports eMMC partition 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
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 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.

Partition table: MSDOS. Disk layout and files as listed in the table below.

Supported fdt files are:
- exynos4412-odroidx2.dtb
- exynos4412-odroidu3.dtb

Supported kernel files are:
- Image.itb
11. USB host support
====================
+NOTE: This section is only for Odroid X2/U3.
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
projects / oweals / u-boot.git / blobdiff
