Greetings (probably for PCW)

 

Background: Running 2.8.0Pre1 on Intel x86 RT-Preempt system. Hardware is
7i80-25 with 7i39. Tests using 7i80hd_25_svsttp6_6_7i39.bit file from
www.mesanet.com/software/parallel and also building it with ISE 14.5 from
source there.

 

Symptoms: 

 

I cannot control the /ENABLE input to the 7i39 (e.g. Pin 17 for /ena0) from
the corresponding hal pin in hm2_7i80. The physical pin is always near +5v
(e.g. 4.95v) - even tested with no 7i39 in case of a back feed through a
fault. Also tested with pin 17 of the second connector (i.e. 3pwm.02) which
will not go low either.

 

The encoders interfaced via the 7i39 count fine and present value to hal. I
can see the Hall sensors in the hal.

 

The four 7i80 LEDs are all ON but can have brightness very slightly changed
by setting True/False on the .led.CR01/02/03  pins.

 

Questions:

 

Is anything known to be wrong with the "enable" in the firmware - I can
paste some INI and HAL if it would help?

 

Is it possible to gain full control over the LEDs - I cannot find where the
VHDL is turning them ON independently of the interface via HM2? I would like
to use them as debug outputs from within some of my own VHDL as well as HAL
(e.g. to track down where the enable signal is getting lost)

 

TIA
