7i80 and 7i77

Hi Andy, thanks for the reply

tried showpin:
franco@knanolcnc:~$ halcmd showpin
RTAPI: ERROR: could not open shared memory (errno=2)

anyway after start lcnc from terminal i get

7i80DB is connected in the first db25 (J2), I thought same as you yesterday due to the name of the .bit file, but when I tried on the 4th (J5) gave me a long list of errors so went back to J2

if i have to map them then, shoul i get the info here ?
linuxcnc.org/docs/html/man/man9/sserial.9.html

if that's the case, can you give me an example... ?

maybe a simple one just to map any of 7i77's TB7 or TB8 physical outputs 0..15

ps: don't hesitate to ask for any other info ie screenshots with halshows / halscopes..

thnks !

If you do not have at least 2 7I76s you probably dont want to use the 7I76x2_7I77x2 config

If you just want something thats close to working with a pncconf config
I would chose 7i80db_25_7i77x4.bit and connect the 7I77 to J2

many thnks Andy

then, went back to J4

this is selection from list of errors

hm2/hm2_7i80.0: Warning: sserial remote device 7i77 channel 1 has old firmware that should be updated


i don't have much clear the sserial stuff besides the basics
to figure out how to solve this or continue (check version / update sserial firmware)

should i connect fieldpower, check out any led, or something else ?


ps1: first time i tried to flash the card i tried (with no sucess I thought) with the

ps2: i could't get control over the 7i80DB's CRs (nor got info what they mean, altough I read somewhere that perhaps were under control of ethernet firmware...) - but this is ancecdotic for now
ps3: ok understood the 5i25 strategy with pncconf (i started that yesterday too but got kinda overwhelmed... so tried to reduce axis, (ie single axis config) but found no options, so maybe i will try with lathe config to start with).

many thanks for your help !

yeah , thanks for the suggestion, PCW
yesterday I tried that too for a while trying to load the .bin with the command

loadrt hm2_eth config="firmware=/home/franco/7i80db_25_7i77x4.bit num_encoders=3 num_pwmgens=2 num_3pwmgens=1 num_stepgens=2 num_leds=4 sserial_port_0=000000" board_ip=192.168.1.121
but did't succeed..
It was too late to remember the problem nor flash anything else but my own brain

Anyway I guess the different behaviour on J4 means the is probably doing what it should.
If i cant solve the issues of my last post with the actual .bin I'll try this one

tnks !

loadrt hm2_eth config="firmware=/home/franco/7i80db_25_7i77x4.bit num_encoders=3 num_pwmgens=2 num_3pwmgens=1 num_stepgens=2 num_leds=4 sserial_port_0=000000" board_ip=192.168.1.121
but did't succeed..

I would not expect this to succeed since you cannot specify 7I80 firmware on the command line

( A 7I77 only config would not have stepgens so would error-out for that reason also )


7I80 firmware is flashed into the card with the mesaflash utility

something like

mesaflash --device 7I80 --addr 192.168.1.121 --write 7i80db_25_7i77x2.bit
mesaflash --device 7I80 --addr 192.168.1.121 --reload

ok. I'll try with fp then see
I'll do my homework best i can..
hopefully come back with good news
many thanks you guys !

ok got it: no 7i80 firmware in command, so i need to flash it manually
(I'm already aware of the proc)

For the record let me tell you that when I first tried to flash the 7i80db_25_7i76x2_7i77x2.bit I got errors
then I realized the existence of 7i80db_25_7i76x2_7i77x2D.bit (note the "D" at the end) and that one flashed ok
later guessed that the "D" probably had to do with 7i80"D"B ...

Now, to flash 7i80db_25_7i77x4.bit I thought I would need something like 7i80db_25_7i77x4D.bit, but coludn't find that file

any idea what the "D" stands for ?

anyway I accept the suggestion but when i decided for the 7i76 / 7i77 combined firmware, I was thinking in the true possibility of purchasing 7i76 to handle some steppers and so... too

Since it seems to be a considerable work to configure all this, I wonder if it won't be wise to give a try with the 7i80db_25_7i76x2_7i77x2D.bit



To avoid problems with steppers stuff in the meantime (ie while maintaining 7i80db_25_7i76x2_7i77x2D.bit and only using 1 7i77),
I tried a simple config disabling stepgens and the like with
loadrt hm2_eth config=" num_encoders=1 num_pwmgens=1 num_3pwmgens=1 num_stepgens=0 num_leds=4 sserial_port_0=000000" board_ip=192.168.1.121

then run ok
no errors
7i77 hooked in J4 and no fieldpower (yet)

and got encoder stuff reported in J4

so what do you think ?
how should i continue ?
