Hi,
thanks for the answers.
If you say you got the x2 to work at the odroid u3, I believe its
clearly a uboot problem.
I had to use bootm twice because the first use gave me the "unknown os"
error.
I think the first bootm call loads the uImage from the preload location
0x70000000 to 0x41000000 and the second one loads it from 0x41000000.
So the first bootm could possibly only be "bootm" without parameter, the
second one needs to have the 0x41000000 to work.
I also tried bootelf with the image.elf and bootp, nothing worked so far.
bootelf freezes quite similar to the bootm command. It says, that its
starting the application.
The script Alexy sent is working and I compiled an image.img in the
meantime and deployed it at the tftp server. I also renamed it to zImage.
Problem still exists.
I tried your uboot code, but I fail to flash it to the sd card.
Am I right that I have to use:
apt-get install device-tree-compiler
(for needed dts, was not necessary at the previous version)
make odroid_config
(make smdk4412_config is not present)
make -j
Is the odroid config for u3?
There is no sd_fuse folder so I am somehow stuck here, because I have no
idea on how to format the sd card correctly and where to put which files.
Would appreciate if you can give some kind of instruction on how to
prepare sd cards or emmc for such devices and flash all necessary files
to it.
I think that my formatting, which leaves the first 1GB of the sd
untouched, is not the best way and I am an absolute beginner here.
Thanks.
Best regards,
Bernhard.
