Hey, Scott (or any volunteer)!

Have you had the time to look at my config files that are causing the following errors? I use the remora-nvem-basic config from github.com/scottalford75/Remora-NVEM/tree/main/LinuxCNC, also attached to this message.

Hello GeremyL, you talked about pins but I don't understand you, XD-, YP-...... are outputs of the am26ls31c differential line driver, this ic has 4 inputs and 4 pairs of differential outputs, therefore this ic convert GPIO_AD_B1_06 ( pad of rt1052) in XD+ and XD-, the GPIO1 module can be connected in this pad through GPIO1_IO22(that is X_DIR_PIN), then XD-, YP-..... are not direct pins of rt1052 GPIO_AD_B1_06 yes it is, So if you have problems with the negative differential signals, I would look for the problem in the line drivers ic. Furthermore, to use these pads as input pins you have to modify the hardware, which does not seem attractive to me, greetings

Can you please share your .txt file you have uploaded to your board and also what is your ping response time?
It helps to add PGAIN to your hal file and .ini file.

Sure! The config is attached. I have tried with both the nvem-basic-config.txt and nvem-full-config.txt, but the result is the same.

This is the respons time:
PING 10.10.10.10 (10.10.10.10) 56(84) bytes of data.
64 bytes from 10.10.10.10: icmp_seq=1 ttl=255 time=0.331 ms

64 bytes from 10.10.10.10: icmp_seq=7 ttl=255 time=0.258 ms

How would one go about adding PGAIN?

Hi, I've had a look at your config files and they are identical to mine, and I can run with a 1000% feed override without following errors....

Now I'm really scratching my head to understand what could be going on. Do you have the serial debug output connected? It would be interesting to see if there are any issues on the board.
 

sudo halcompile --install remora-nv.c

pip3 install pyocd

python3 upload_config.py config.txt

Ping response times are longer than I'm getting though, averaging around 0.17ms. Do you have a router in between the NVEM and computer?

Let me explain exactly what I have done. Maybe you can spot something that I've done wrong.
- Full chip erase on NVEM using STM32 ST-LINK Utility
- Flash NVEM with Remora-NVEM-STM32-1.0.0.bin from github.com/scottalford75/Remora-NVEM/tree/main/Firmware using STM32 ST-LINK Utility
- Install Raspberry Pi OS (Legacy) 32 bit
- Install LinuxCNC and realtime Kernel according to forum.linuxcnc.org/9-installing-linuxcnc...n-raspberry-pi-3b-pi
- Copy github.com/scottalford75/Remora-NVEM/tre...es/remora-nvem-basic to /home/pi/linuxcnc/configs
- Copy github.com/scottalford75/Remora-NVEM/tre...Components/Remora-nv to /home/pi/linuxcnc/components
- Install remora-nv component using

sudo halcompile --install remora-nv.c
- Install pyocd using [code]pip3 install pyocd
- Write config to NVEM using [code]python3 upload_config.py config.txt

And that's it I think. Can you spot anything I might have done wrong?

I do not have the serial debug output connected, but I can do that if there is a guide I can follow. Do you happen to have one? [img]/media/kunena/emoticons/smile.png[/img]

No router. 2 meter cable directly from the Pi to the NVEM. Is the response time high enough to cause these errors you think?
