Custom firmware for 7i90HD

Hi PCW,

Could you please generate a custom firmware for 7i90HD card?
Whis of my customer is to have all 5 stepgens , 1 pwmgen and 1 encoder on first connector of 7i90, so the 2nd and 3rd connector may be used for GPIO pins.

BTW: We'd like to order 8 or 10 pcs of 7i90 from webshop but for several weeks it is out of stock. Will you have it restocked soon?

Thank you very much in advance.

Best regards:
Janos

7i90s are being built now and should be available again soon

Hi Peter,

Here is the pinout:

Connector P1:
IO Pin 000 StepGen #0, pin Step (Output)
IO Pin 001 StepGen #0, pin Direction (Output)
IO Pin 002 StepGen #1, pin Step (Output)
IO Pin 003 StepGen #1, pin Direction (Output)
IO Pin 004 StepGen #2, pin Step (Output)
IO Pin 005 StepGen #2, pin Direction (Output)
IO Pin 006 StepGen #3, pin Step (Output)
IO Pin 007 StepGen #3, pin Direction (Output)
IO Pin 008 StepGen #4, pin Step (Output)
IO Pin 009 StepGen #4, pin Direction (Output)
IO Pin 010 Encoder #0, pin A (Input)
IO Pin 011 Encoder #0, pin B (Input)
IO Pin 012 Encoder #0, pin Index (Input)
IO Pin 013 PWMGen #0, pin Out0 (PWM or Up) (Output)
IO Pin 014 PWMGen #0, pin Out1 (Dir or Down) (Output)
IO Pin 015 PWMGen #0, pin Not-Enable (Output)
IO Pin 016 IOPort
IO Pin 017 IOPort
IO Pin 018 IOPort
IO Pin 019 IOPort
IO Pin 020 IOPort
IO Pin 021 IOPort
IO Pin 022 IOPort
IO Pin 023 IOPort

Connectors P2 and P3: IOPorts on all pins

Hi PCW,


Thank you very much for the firmware.
I flashed it was unable to test, because I got the following error:

Kernel: 2.6.32-122-rtai, LinuxCNC 2.6.4

HAL file:

loadrt hm2_7i90 ioaddr=0x378 ioaddr_hi=0x0778 config="num_encoders=1 num_stepgens=4"

The same I have with Machinekit / rt-preempt / rtai kernels.

Should I make further tests, or make bug report somewhere else?

I would try on a current system
(wheezy, Linuxcnc 2.6.7)

Tested on Wheezy / 3.2.0-4-rt-686-pae kernel / LinuxCNC 2.7.0pre4: the same result, undefined symbol: hm2_unregister

can you try the iso image? looks like possibly a compilation issue?

Edit:

did you loadrt hostmot2 before hm2_7i90?
