Hi Kyosti, Sorry, I reread your first reply and it became clear what you meant when looking on the Chomebox's /var/log directory. I found the port at the back corner of the Chromebox is numbered 2-1.2. None of the external ports connect as 1-1.2. Connecting the phone with the EHCI debug device enabled kernel to the 2-1.2 port and booting Ubuntu on the Chromebox I see the following in kmesg:
[ 2.008799] usb 2-1.2: new high-speed USB device number 3 using ehci_hcd
Assuming usb 2 is PCI 0:1d.0 (which would have been clearly identified in parts of the log you did not send), use USBDEBUG_HCD_INDEX=1 for coreboot build.
Default kernel configuration will not output anything on usbdebug. Now that you know the correct physical USB port, have the phone powered on and connected, run 'cat /dev/ttyGS0' and then boot the chromebox with the coreboot image with usbdebug feature enabled.
On this boot, what do you get for dmesg output on the phone side? Just send the complete log or put it available for download without separate request.
If still nothing interesting appears, you could try coreboot with spkmodem console and possibly POST display card, but I do not know how to connect those on chromebox.
And.. last but not least, the instructions you followed, did they have a step with 'make crossgcc'?
