hi Guys,

I'm trying to subscribe to rising edges on 8 GPIOs. I have found this 
online about the beaglebone (not black):


*A maximum of 66 GPIO pins are accessible from the expansion header. All of 
these pins are 3.3V and can be configured as inputs or outputs. Any GPIO 
can be used as an interrupt and is limited to two interrupts per GPIO Bank 
for a maximum of eight pins as interrupts.*
Is the same true for the BBB? I've not tried all the ports, but I've only 
been able to get 3 interrupts working so far. Furthermore, how are the pins 
banked? The reference manual is silent on this subject. I found a table on 
page 70-72, which groups the GPIOs under "Mode 7: as belonging to 0,1,2, or 
3 -- is this what is meant by different banks? 

What are the limitations on interrupts for the BBB? Why is this nowhere 
mentioned (that I could find??)? Thanks!
