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
