New project, litehm2: a hostmot2 port to linsn rv901t

I built the bitstream, it is in the attachment. I only tested that mesaflash --readhmid still works with it, so please test carefully. It you want a different pinout or other function, please edit the attached conf file and send it to me, so I can compile a new bitstream for you. 
    

Thank sensille
The bit firmware can work normally, and the tool for modifying the circuit board is still on the way, so no further testing is possible

   Dear Sensille
  I think I may not use the encoder index, so that there are a few more inputs, can you help me rebuild the bit file?

New bitstream is attached, but it wouldn't have been strictly necessary. The encoder is just the secondary function. You can also just use any encoder input as ordinary input. The same holds for output, you can use the stepgen outputs you don't need as ordinary outputs as well.
 

Can you link to aliexpress for the correct board? I have 5A75E but it seems the project has stopped development. This project seems to work well.

rv901t is the correct designation. Bonus if you can read "spartan" on the FPGA chip in the product picture.
I'm also working on making this project available for 5a75 (lattice ecp5), but I can't say how long it will take.

This is very good news! Thanks !

Dear sensille
Your bit file is # J601, 40 pins
# Buffered through U603: 7-14 out
# Buffered through U607: 15-22 out
# Buffered through U602: 23-30 out
# Buffered through U606: 31-38 out
# Buffered through U608, shared with J600: 39-45 out
#
# J600, 32 pins
# Buffered through U600: 7-14 in
# Buffered through U604: 15-22 in
# Buffered through U601: 23-30 in
# Buffered through U605: 31-38 in

In case of RV901T you should cut one trace in two places then solder it to GND and add a smd 0805 1k resistor to 3V3. In the end you will get U603, U607, U602, U606 as input and U605, U601, U604, U600 as output ports.


The result of your transformation is the opposite, can you recreate the bitfile of the transformation method IlyaKw wrote?

Please check if the config suits your needs. The pin assignment is different.



 

I pushed some commits to master that add the modules inm, inmux and sserial. The latter two are untested.
