Any
pointers? Web search comes up fruitless except for references to the
kernel source code which I don't understand. ;) Thanks, John.
Hi John
Apply the patches and follow the instructions here for BeagleBone
Black
kernel:
http://www.coreboot.org/EHCI_Gadget_Debug
In coreboot menuconfig, the selection of usbdebug dongle 'BeagleBone'
is
only for 'BeagleBone', not 'BeagleBone Black'. I better add option
for 'BeagleBone Black' to avoid the confusion. Select 'Net20DC
compatible' for now.
Also in coreboot menuconfig, under 'Debugging', enable verbose
usbdebug
messaging. Of course you will need another working console to receive
those messages, CBMEM console will do if your target system is able
to
reach OS.
Regards,
Kyösti
Hi Kyösti,
Man, you are quick. :)
Yeah, I followed those instructions. The BBB's kernel and modules have
been compiled with the patches.
Ah, that explains part of it then, because I had selected Beaglebone as
opposed to NET20DC or compatible.
It isn't able to reach OS, but if changing the coreboot menuconfig
doesn't fix it I shall try it on a Chromebook which is working with
coreboot, and revert.
Thank you!
John.
