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.

Yes, I tried it also in the hm2_rpspi config string.
The message is here " invalid token in config string: "num_ssrs=0" "
 
It bug in hostmot2 driver(hostmot2.c: hm2_parse_config_string()), no code for reading "num_ssrs=" value.
Affected 2.8 and 2.9, in 2.7 hostmot2 driver not support ssr.
Fix code:
Code:
        } else if (strncmp(token, "num_ssrs=", 9) == 0) {             token += 9;             hm2->config.num_ssrs = simple_strtol(token, NULL, 0);

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)?

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.
