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
We can assume, that the aboce steps are ok.
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
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/hardker...
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/
