net spindle-vel-cmd-rpm-abs => pyvcp.spindle-speed

Sorry, that is exactly what i meant, and it is set correctly, so the scaling might be off.
That is if you are not using an encoder for the feedback.

Thanks for the feedback, I thought it was scaling causing it, but as I have no idea what I'm doing (just using the 'suck it and see' method) any help in understanding it is always appreciated.

Recycling an old thread, I have mesaflash and modcompile but cannot find where the .bit files are. I want to enable a pkt_uart on my 7i96 but can't seem to figure out how to do that. My ultimate target is getting Andy's modbus driver for mesa cards working.

Download the "support files" here:

You might need to expand zip files inside the zip file to find the Hostmot2 source, but the bitfiles should be there.

However, it might be more useful for me to just attach the 7i96 butfile that I used for all my modbus testing :-)

I may have mentioned this before, but I wrote my own HAL component VFD driver. It uses the pymodbus library and attaches to a host serial port, in this case /dev/ttyUSB0, as a RTU client. I'm wondering if it's possible to attach to the 7i96 pktUART as a TCP client. This would allow me to keep the VFD driver but eliminate the USB to RS485 dongle.  I will research this but would be grateful for any insights. Thanks.

You can connect to the 7i96 pktUART as an RTU client, but not as a TCP client.

I did
mesaflash --device 7i96 --addr 10.10.10.10 --backup-flash 7i96_firmware.bit
and that worked. Then I did:
mesaflash --device 7i96 --addr 10.10.10.10 --program 7i96_pktdv2.bit
and got
ERROR: Board 7I96 doesn't support FPGA programming.
readhmid works fine. What am I missing?
