Uploading doesn't work I'm getting time-outs and now after a single movement I'm getting a following error:

Did you upload the new firmware from this location? [I'll correct the earlier post]

github.com/scottalford75/Remora-NVEM/tre...json_config/Firmware
 

Need to change the address from 10.10.10.11 to 10.10.10.10? Or is it a card address?

The NVEM board IP address is hard coded to be 10.10.10.10 , Your computer can have any IP address on the same subnet.

You need to be in the same directory as the python file and the config file before running the command.

Yes I did upload that firmware and checked if it uploaded correctly

Hmm... ensure the ST-Link is disconnected and try pinging the NVEM at 10.10.10.10

Yes I could ping it, was thinking the same. Will try to upload the bin from the Release folder

I'll look to merge the feature branch into main later today. Until then this is the firmware for testing

github.com/scottalford75/Remora-NVEM/tre...json_config/Firmware

Downloaded the whole folder so it has a new name so it could not be from the cahce or something, uploaded the firmware again, but still the same result. Time out when I try to upload the config and directly a following error after each movement. Ping is 0.090ms

I've got a thought. Not sure why the upload is not working but when loading a fresh firmware there is no JSON config file in the Flash either, so when the board boots it's loading nothing, not even a stepgen. I'll need to include a default configuration in the firmware image somehow.

Really appreciate the testing guys. We'll get there.
