mesa card 5i25 kernel error

today I have use the 5i25 folder from mesa site.

in the utility folder there is mesaflash..... I use it ..... mesaflash --device 5i25 --reload is't present ..... than I have reboot after --write command ...I used --verify command with succes. With sudo nautilus I copy bit file xml and other in a new 5i25 folder on /lib/firmware/hm2 folder

In the pncconf wizard in the page for choice the board I select 7i77x2 .... but I have only one (no problem for this). I have 5 axis and 1 jog wheel, than I select 6 encoder.. no other choice is possible (pwm or other). I can choice only number of channel or number of smart serial (obviusly i can select or deselect external card "saNITY CHEK").

If select 1 smart serial (or two) I can see tb8 and tb7 and analog output, otherwise i can see only i/o 2 connector and i/o 3 connector.

Is normal these?

I ask because when launch axis all work fine but i steel see the error in the sreenshot-34.pgn posted at the beginning.

Tomorrow I try with install mesaflash from repo.

The sserial errors probably mean that you dont have field power supplied to the 7I77s digital I/O section

You also have a real time delay error that is unrelated (perhaps you need to run the latency test to check the PC)

Ok. than the windows that I see is ok.........


the 7i77 have 5v external power and field power to 24V.
Connector 1-2-3-4 is on +24Vand nr.8 to 0V (switching ac dc power). VIN connector is free and W1 in left hand position.

latency test running with several open windows show 5000-6000 and is totally similar to these:


the pc is an ASRock AD2550B-ITX ....... the 5i25 metal base in directly grounded on the switchboard, is this a problem?

In set up I have write the servo period to 1000000.... I not see the label for base period set up (I must only run latency test in the set up?)


I connect some button and a jog whell .... it works fine and I see it working ok on hal scope and in halmeter pin/signal section..... I have not connected anlog out to drive and pulse input to encoder, except a jog wheel.

You do have a real time fault of some kind (The last message on your screen shot)

No sure why you are having communication errors.
These are usually related to cable problems or power supply issues

What parallel cable are you using (is it one from Mesa or dId you supply it)
and what length is the cable?

EDIT
just noticed:

always use for testing a flat cable 80cm and 5V external .

This is probably an issue, flat cables of any significant length are not suggested
Unlike flat cables , the suggested IEEE1284 cables have a twisted pair per signal
and much better grounding




Did you check the 5V and 24V at the 7I77

Since you are supplying 5V power to the 7I77, Is the 5I25 jumpered so cable power is disabled?
(5I25 W1 down)

Is the 7I77 jumpered for external 5V power?
(7I77 W5 right)

Ies I use 80cm flat cable for test only. In production mode I use parallel cable ieee 1284 .....
I not chek the 5V capability ..... I remembered that sometimes , these power supplies that use 5V are not calibrated correctly at 5V and must calibrate ....

Did you check the 5V and 24V at the 7I77

Is the 7I77 jumpered for external 5V power?
(7I77 W5 right)

Than no ... I not control the 5V measure .... and 24V too ...is possible that: 5 volts can actually be a little less ... 4.2 for example ... but I can adjust

Yes the jumper are ok.

Tomorrow adjust the voltage and re-test all....

ok ... now is my situation:

1 - I've install mesaflash from repo. I write 7i77x2.bit file with new mesaflash.

2- I control the power and adjust it (in the past it is not so good) now I have 24,4V and 5.3V power supply.

3- 5i25 have: w1 down -- w2 downd -- w3 up -- w4 up -- w5 up

4-7i77 have: w1 left -- w5 right all other equal to image on the manual

5-in 7i77 pield power nr. 1/2/3/4 connector is at 24.4V nr. 8 to gnd

6- encoder 5 is connectded (external jog weel) other is free

7- dvr0 to dvr5 is free

8- TB7 connector 16-23 is connect to input (+24 powered) all other is unconnected

9- TB8 is unconnected

10 - I re-reun pncconfig and re-run latency test with several windows and 2 video online (youtube) .... maxjitter 12000/13000 (I think is all ok ... is right?) I set 3 channel and 1 smart serial ... I set 6 encoder and 5 pwm and 24 input and 16 output ..... in the field that appear for 1 channel for an other 7i77 I/O board (or other) I write "unused" ...

This is the result .....



I can add a ieee1284 cable .... not change the situation .... the machinery is not running!!

this the dmesg file :




some other suggest?
