Hi,

I guess, the max ic i used for smartserail is to slow. I tested my board with a frequency generator and it worked as expected on lower speed. Guess the am26Cxx (which I used for step interface) would have been better choice for smart serial ...
.

Do you have any access to a Mesa sserial BoB to test with?

So I bought a 5i24 together with a 7i47 (which should drive the stepper through differential lines) and a 7i44 for smartserial cards.
But I realized, that the 5i24 is shipped with a dummy firmware only, that supports just ioports/leds ...
Is there a firmware, that combines the new cards I got - and if so, which one is it?

5i24_16_sssvst8_1_5_7i47.bit

5 Step/Dir, 1 PWM, 4 encoders on 7I47 (P4)
Plain GPIO on middle connector (P3)
8 SSerial interfaces on a 7I44 (P2)

is probably close to what you want
(assuming you have a -16 card)

Yes, I have a -16 card.
7i44 on P2 is ok, but 7i47 is not what I intended.

I want to use as much steppers on the 7i47 as possible (I read about 12 steppers).
Encoders are a later option.
At start I want to drive steppers with the 7i47, use analog channels of a 7i33 for overwrite knobs and 8x8 keypad on each 7i33 for keyboard and GPIO on 7i33 should be fast enuf for endstops or so.

PWM - yes I want pwm, but I don't know, where it will be best located.

When I buy encoders (I plan about magnetic absolute encoders with serial interface), I'll probabely have to buy another daughter for the 5i24 ...

What do you think?

Argh - 400 bucks wasted and same result :(

I tested the bitfile 5i24_16_sssvst8_1_5_7i47.bit
7i47 and 7i44 connected and powered with separate power and connected 7i73 on channel 0 and channel 1

hal documentation says, that config options for 7i44 could be found in mesa doc - did not find anything in there.
So i tried the same commandline as with 5i25
Code:
halrun loadrt hostmot2 loadrt hm2_pci config=" num_encoders=5 num_pwmgens=1 num_stepgens=5 sserial_port_0=1110xx"
first the output from mesaflash

next the output from loadrt hm2_pci:

and last the output from show pin:

File Name: 5i24_pinout_X.txt

no smartserial or any pin of a 7i73-card found.

I additionally searched the forum for 7i44, but it looks like other users needed a bitfile, but no one asked for hal config options. What am i missing?

P.S.: the 7i73 cards did not change red led
P.P.S.: i discovered the --serial option for mesaflash. Output is:
Code:
SSLBP port 0: SSLBP Version: 1.43 SSLBP Channels: 8 SSLBP Baud Rate: 2500000
