Gene,

I believe for testing the SPI connection ssh will do it.

The hostmot2 part of the ini file should have:

    [HOSTMOT2]
    DRIVER=hm2_rpspi
    BOARD=7i90
    CONFIG=""


but I think you know that.

Testing with halcmd:

    halcmd loadrt hostmot2
    halcmd loadrt hm2_rpspi

expected output:

Good luck again!
