I have connected everything and flashed the bitfile from PCW. But it looks i have not configured the second card in the hal properly.
Attached the output of mesaflash readhmi, the hal and the crash report from lcnc
any ideas?
thanks in advance.

HAL: ERROR: function 'hm2_7c81.1.read' not found
./intos.hal:16: addf failed

should be
hm2_7c81.0.read

Hi,
thanks for your fast reply.
if you read in the hal, there is written :
addf hm2_7c81.0.read
addf hm2_7c81.1.read
for both cards
.0 is the 7i77 and .1 is the 7i78
I interpreted the documentation that it should be done like this.
Any advice how it is configured correctly?

How many 7c81 are in use?
for one only, delete the line containing 1
addf hm2_7c81.0.read
addf hm2_7c81.1.read
Pretty sure this should only be used if you have 2 of 7c81, 0 and 1 there are enumeration for 2 of 7c81 not the add on cards, they do have their own enumeration after the model number, example:
hm2_7c81.0.7i77.0.0.input-07
First 7c81 that has the first 7i77 attached, first is always 0 with Mesa and LinuxCNC enumeration.
Had a look at your hal, there is more editing required, so it might be easier to make a new config with a single 7c81.

Hi,
only one 7c81, you tip has done the trick. Thank you!
but the next problem occured

The error changed to:
/intos.hal:88: parameter or pin 'hm2_7c81.0.7i77.0.1.analogout0-scalemax' not found

so checked this line in the old, working hal, without the 7i78, and its exactly the same. What does change here when i use 2 daughterboards?
Any Ideas?

EDIT:
i have also tried to change the channel number to 0:
hm2_7c81.0.7i77.0.0.analogout0-scalemax'
and 2 and 3

Try omitting that line with scalemax, right now i can not recall i ever used it.
Just add # in front of the line, save, test.
