New project, litehm2: a hostmot2 port to linsn rv901t

You load the driver with multiple ip addresses specified
The hal pins/parameters will have different board numbers.

Its also important with multiple cards to use the read-request function
so that the second card does not have wait for the first card to respond
before its read data request is sent.

I did notice that in litehm2.py there are imports for "M12L64322a" and "GENSDRPHY", though they do not appear to be used anywhere. I just wanted to confirm that they aren't required for functionality. 
 
Sorry for the late reply. Yes, the SDRAM is not used, only internal resources (BRAM).

You should carefully read a little instruction.

Help me please.
It seems that I’ve done everything and the bit files change when uploaded, but for some reason I can’t start Linux sts. What am I doing wrong?

report?
 

Did you read the section regarding patching the linuxcnc driver ? Because of the 1G bit network interface on The colorlight card.
It may be worth updating Linuxcnc so that you are running a version that has the patch included.
That is if you haven’t already done so.
