Hi all,
I have a EC500 board which I flashed with the firmware remora-rt1052-2.1.1.bin
When I upload "ec500-rt1052-DMA.txt" with upload_config.py I get the message "JSON config length incorrect" from the EC500 console.
 

I tried different files and all gave the same result.

Regards, Hans

Addendum:
As a test I flashed "remora-rt1052-1.1.0.bin" and then I can upload the config file.
So that seems to be a bug in the most recent firmware file.
 
Hi, I've tried to replicate your issue. A full chip erase and firmware flashed from repo. Using your config.txt I get the following successful result..
Code:

Hi there

I wonder if I could just get you to confirm that.
I have flashed  remora-rt1052-2.1.1.bin  & am still seeing this at 24v all the time.

I have uploaded some pics. Its not so clear in the picture but all of the LEDs are off. 
If yours is working normally then I'm thinking it might be a hardware failure on my board.

Thanks
Alex

Has anyone experienced stuttering/jerky stepper motors?

I just installed the NVEM board back in the mill after having it on the desk while setting up LinuxCNC. The machine moves and homes, but during jogging the stepper motors stutters or jerks or possibly skips steps.
The hardware setup is untouched since running Mach3, so I'm confident it's not related to the steppers, drivers, wiring etc. Could implementing PID help? If so, what would be the right way to tune the parameters?
My hal and ini are attached if anyone wants to take a look.

Something like this?
forum.linuxcnc.org/18-computer/44828-rem...rd?start=1310#283944

Make sure you are using the latest firmware (link at bottom of page 134)

Also I found adjusting this helped.
PGAIN = 70

Hi all,
I have a EC500 board (RT1052) which I flashed with "remora-rt1052-2.1.1.bin" and uploaded my "ec500-rt1052-DMA.txt"

I can't set any outputs (LEDs) nor read any inputs (switches, NC).
Set outputs can be monitored by wireshark, but apparently the will not be processed by the EC500.

I will use stepper motors with integrated feedback ( www.aliexpress.com/item/1005005276593086.html ).
When testing moving a motor it also doesn't get any signals.

I'm at the wits' end!
What am I missing or what is wrong?
Do I need additional signals for the EC500 to enable its operation?

I hope a knowledgeable sees the problem ;-)

Regards, Hans

Yes, looks and sounds like the issue I have. My NVEM has the STM32 MCU, so it is not the same firmware as for the RT1052 unfortunately.
