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/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.
