Hi Bernhard

It does not seem to be a network or usb problem. Clearly the uboot is loading the image from TFTP server. Why do you use two bootm calls, if you only load the uImage in address 0x70000000?

When uboot is usesd to boot some operating systems like android or other linux distributions bootm can be used as:

bootm $(kernel_addr) $(ramdisk_addr)

But this only can done if there are loaded on memory the kernel and the ramdisk.

In this case GenodeOS don't use ramdisk, it uses only kernel image.

I think that the problem with Genode can be the image format. As Alexy Gallardo explains we have tested the Odroid-U3 with the Odroid-X2 support, but we boot the image with the bootz (at address 0x41000000) command because we use a zImage format created with the raw_image script that him attached to you. Your uboot seems to don't have this command (bootz), maybe it can be enable on uboot compilation.

Now i'm not in work to see the source of Uboot that we are using, but take a look on this Uboot project with support to Odroid-X2 and Odroid-U3.:

https://github.com/dsd/u-boot

Have you tried boot the elf image with bootelf? Or have you tried to boot the same image from an storage device to test it first and then move it for the tftp?

Best regards

Hi all,

tried something else instead.
Deleted the whole sd card again and flashed it with a fat32 partition starting at 1GB to ensure I don't write some place, that is rewritten when sd_fusing script writes boot data to sd card.
I feared that if i load 0x41000000 it could be the zImage kernel which is on the sd card already.

I also have to correct myself i have to use the usbnet uboot code from here: https://github.com/mkaczanowski/u-boot/tree/odroid-u3-usbnet
Otherwhise it wont boot the usb parts(network card).


Now I used the uImage from Ubuntu from the tftp server and the uImage from the genode build.
The boot.txt looks like this:

setenv ethact sms0
setenv ethaddr 00:10:75:2A:AE:E0
setenv gatewayip 192.168.0.254
setenv netmask 255.255.255.0
setenv serverip 131.159.12.22
setenv usbethaddr 00:10:75:2A:AE:E0
setenv ipaddr 192.168.0.23

usb start
tftp 0x70000000 odroid/uImage
bootm 0x70000000
bootm 0x41000000

Boot uImage now seem to work, Ubuntu runs to its kernel panic again but Genode now unfortunately hangs at Starting kernel.

Is it possible that now all is running as expected but x2 genode code can not be used at u3?
I'd expected that i should at least be able to boot, even if some usb drivers or something will not work?


Best regards,

Bernhard.

Hi Christian,


thanks, this did not fix the problem either.
I tested it with the uImage from ubuntu and the uImage from genode.

Best regards,

Bernhard.

Hi,

I've just a small hint regarding the following issue.

On Wed, Jan 25, 2017 at 07:30:11PM +0100, Bernhard Blieninger wrote:
  mkimage -A arm -C none -T script -n 'Custom Boot Script' -d boot.txt boot.scr

Problem now is that is says something like:

    *ERROR: booting os 'Unknown OS' (3) is not supported*
When generating an uImage mkimage supports to set the operating system
in the commandline via '-O <os>'. So, your mkimage command line should
read

   mkimage -A arm -O linux -C none -T script -n 'Custom Boot Script' -d boot.txt boot.scr

Hope it helps
