7i96 (non s) and BOB causing the mesa 7i96 to power off.

Hey Everyone, 

I flashed a mesa 7i96 (non s) with the 7i96_5abob_d.bin firmware, and tried to connect the bob but it would cause the 7i96 to power off every time.

With the ethernet port facing the left. Red line on the cable (pin 1) is pointed up (closer to the ethernet port). If i flip it around it doesnt short but it also does nothing. (flipped every gpio pin above 34 pins output and wasnt able to cycle the onboard relay) also steppers didnt move.

Tried with a second 7i96 with the same result. 

I've tried powering with the usb, powering via terminals, removing the jumper on BOB, adding the jumper. Nothing works.

Funny enough i have a 7i96s with a bob that works perfect. Tried to connect the 7i96 to that bob with its cable and it still shorts. So its not the wiring or the bob, its prob the firmware on the 7i96.

I've power cycled and used readhmid to verify it got the flash. The only odd thing is it has 3 steppers not 4. I also tried the 7i96_g540 flash to see if that would help but same issue.


Any help would be great.

Here is the board. Tried another green one that looks just like it with the same issue.

Make sure 7I96 W8 is in the down position.

If not, standard parallel port BOBs will short out the 7I96 5V supply

(W8 should only be in the up position for Mesa daughtercards that
get 5V power from the 7I96)
 

Doh....That was it!

Thanks!
