You added it to config string?Where i have to add num_ssrs=0. If I add it into .hal there is a error "unknown command".
loadrt hm2_rpspi config="num_ssrs=0"Please Log in or Create an account to join the conversation.

Yes, I tried it also in the hm2_rpspi config string.
The message is here " invalid token in config string: "num_ssrs=0" "

Is there any manual where the ssr funktionality is explained?
The output in the HAL Configuration says that hm2_7c80.0.ssr.00.out-01 is off (yellow) All other outputs are red.
The hardware switches all outputs to high.

Affected 2.8 and 2.9, in 2.7 hostmot2 driver not support ssr.
Fix code:

Yes that was missed because there is no actual hardware where
disabling SSRs makes sense . For the OPs use, 7C80 firmware with no SSRs
makes more sense

Oh.
What I have to do if i have to compile linuxcnc with fixed driver?
Follow this steps?
Can anybody make a bit File with following Pinout (IOPort<=>Pin from 7c80spi.ucf)?

Does anybody knows what th ssr funktionality is for?
Out0..7 in phase with AC Ref == on and Out0..7 out of phase with AC Ref == off.
The only logical for following hardware is a XOR chip. We never have seen sth like this and i cannot find sth about it.

It makes zero sense to change the driver, you need to make a
bitfile that matches your hardware.

If you take the pinout file that D.L. provided and edit it to:
1. Add your additional encoders, sserial ports and PWMgens
2. Remove the inmux (actually not sure here if your hardware include the muxes or not)
Either D.L or I can take that new pinout and make a bitfile that
matches your hardware.
