Hello,

i am using a cramps board and have a problem running my encoded spindle, it 
looks like the impulses of the Encoder pin B are not being recognized (also 
when i switch the physical pins A and B on the cramps board, so it has 
nothing to do with the encoder).

Here are my connections:

Pin A (Encoder) goes into SCK on the Cramps board (P9.31 on the Beaglebone 
and set to input) and on the Beaglebone header on the backside i have 
soldered it to P9.42 (also input), and P9.92 is set to either Pruin/QEP

Pin B (Encoder) goes into MOSI on the Cramps board (P9.30 on the Beaglebone 
and set to input) and on the Beaglebone header on the backside i have 
soldered it to P9.27 (also input)

Pin Z/index (Encoder) goes into SPI_SC0 on the Cramps board (P9.28 on the 
Beaglebone and set to input) and on the Beaglebone header on the backside i 
have soldered it to P9.41 (also input), and P9.91 is set to either Pruin/QEP

when i use halscope, i can see the counts on pin P9.30 but not P9.27 (P9.30 
is soldered to P9.27) 

i also checked the connection with a multimeter

btw recently i turned the beaglebone/cramps board combination at 90° on the 
side to look for something while it was on and then BAM, it just switched 
off, wont turn on again and even when i plugged all the power out and in 
again it would not start (did not even light the 4 blue leds on the board), 
my pc did not recognize the beaglebone properly and i had to manually 
install the drivers and then it magically worked again. Nothing shorted 
anything on the board because atm it sits on a towel.

i hope someone can help me
