Mesa 7i48 servo card - no input signal.

OK the FPGA configuration file is in the HAL file since this setup
was created with pncconf.

The configuration is here:

loadrt hm2_pci config="firmware=hm2/5i20/SVST8_4.BIT num_encoders=3 num_pwmgens=3

(SVST8_4.BIT) which is not the correct FPGA configuration for a 7I48

Does pncconf have a option to select a 7I48 daughtercard?

Phew - we changed the firmware option and it worked. Nearly 3 days to get this to run.

Ok so which is the correct one.

I have

5I20 7I37 7I48

SV12
SV12_2X7I48_72
SV12IN_2X7I48_72

There are other options but these seem the most logical.

As far as I know with the distributed bitfiles, only ones with 7I48 in the
name are appropriate for use with the 7I48

Thanks. We used the SV12_2X7I48_72 and it worked.

Next issue Limit switches ?? They work in the PNConfig but when I try and run I get a error. Tried inverting signals but still the same.

I have posted it under a previous discussion on it
