Hi, All.
I connect the Beaglebone Green with expansion connectors to fully utilize all gpio pins. (possible 65 gpio's)
To avoid eMMC conflict, not to use P8.3~6,P8.20~25, since my BBG was booted from eMMC. 10 pins gone.
As shown in the picture 1, I can not boot BBG but with only power led on.
Remove connector (pins P8.39~46), then I got BBG boot with all leds on but my notebook says the USB unknown device can't function.
After remove the other connector (pins P8.29~38), then I got all normal boot and functioning.
So how can I use the SYS_BOOT 16 PINS as GPIO's, which corresponding to P8_31~46 pins of BBG !
from BBB SRM Rev.C.1
If BBB can use all these SYS_BOOT pins for hdmi lcd, so can BBG uses these pins as gpio's?
Thanks in advance.
