[U-Boot] Mainline u-boot installation on Odroid-UX4

[U-Boot] Mainline u-boot installation on Odroid-UX4

[Shawn Guo]

Hi Przemyslaw, Anand,

I just got a Odroid-UX4 board to play.  I installed firmware (bl1, bl2,
tzsw, u-boot) from hardkernel using sd_fusing.sh, and the board boots
fine.  But when I install mainline u-boot v2016.03 by following
doc/README.odroid, the board refuses to boot with nothing appearing on
serial console.

Here is what I did:

 - make odroid-xu3_defconfig
 - make (using arm-linux-gnueabi-gcc 4.7.3)
 - copy u-boot.bin (which is same as u-boot-dtb.bin in v2016.03 release)
   to sd_fuse/hardkernel folder, and modify sd_fusing.sh to get it point
   to this new U-Boot
 - ./sd_fusing.sh /dev/sdX to flash the SD card

One thing I'm not sure is the offset that firmware should be installed
to SD card.  The doc/README.odroid and hardkernel sd_fusing.sh tells
different ones.

doc/README.odroid:

 -------------------------------------
|  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 | 2560 | 2560 |  0 (user) |
 -------------------------------------

sd_fusing.sh:

signed_bl1_position=1
bl2_position=31
uboot_position=63
tzsw_position=719
env_position=1231

I tried both sets, and neither works for me.

I know Odroid-UX4 is supported by mainline U-Boot today, so there must
be something missing from my setup.  Could you please help me here?
Thanks.

Shawn

We can assume, that the aboce steps are ok.

There were two variants of boot chain with U-Boot for XU3/XU4, which 
differs in U-Boot size - originally U-Boot was 328K, but for the 
mainline we assume 1MB of size.

So for mainline, you need a prober version of BL2, which loads 1MB of 
U-Boot instead of 328K - in other way, the mainline U-Boot will be 
overwritten by tzsw and env.

Please use the resources from this site:
https://github.com/hardkernel/u-boot/tree/odroidxu3-v2012.07/sd_fuse/hardkernel_1mb_uboot

In sd_fuse.1M.sh, you can see, that for U-Boot area we have: 2111-63 == 
2048blk == 1MB.

And of course change the U-Boot to mainline.

Adding to this you requires

mainline u-boot requires boot.scr file to boot.

$ mkimage -C none -A arm -T script -d
board/samsung/common/bootscripts/autoboot.cmd boot.scr
$ cp boot.scr /media/boot/

Because Przemyslaw Marczak has implemented card detection logic for
Odroid XU3/XU4 board.

You need to use following exynos5422-odroidxu4.dtb DTB file in /media/boot/

Thanks much, Przemyslaw.  It works now.

I think we should update README.odroid a bit to ease future users.  Do
you prefer something like the patch below, or we simply replace the
existing link with hardkernel_1mb_uboot one, considering the default
U-Boot image today is already bigger than 328KB anyway?

Good point, it wasn't updated for a long time. Yes, useful U-Boot's size 
is much bigger than 328k, so you can just, replace the link.

It would be nice if you could update the supported fdt files list at 
line 25 of doc/README.odroid - with file: exynos5422-odroidxu4.dtb, 
mentioned by Anand Moon.
