2 weeks ago Hi @scottalford75 , I really appreciate the work you have done and has made it a lot easier for us beginners like me. I have researched quite a bit here and there. Went through the code and some other stuff. What i have come up with so far is that the board (W5500-EVB-Pico) shall take the stepgen, dir, inputs, and outputs from the JSON file that we upload through the upload_config.py. And it works fine as long as there are no outputs placed in the JSON file. If the mode of only a single digital pin is set to output. The board doesn't work then. And we can observe that from the blink pin - GP25. it doesn't blink then. Which shows that it didn't upload.
I also went through the linuxcnc forum and this guy "telmoram" also had this issue and nobody responded to him. The link is given below to his exact same matter: https://forum.linuxcnc.org/18-computer/49156-remora-for-rp2040?start=90
This sam issue also appeared when i was going through the github page: https://github.com/scottalford75/Remora/issues/11 here @aaroncnc also had issues with outputs and then you went on and said there was something wrong with the data structure packing was the issue meaning that the "outputs" data byte was not included in the SPI packet.
And yo said, "Ok, I've found the problem. It looks like the data structure packing was the issue meaning that the "outputs" data byte was not included in the SPI packet.
Structure corrected in both remora.c and firmware. Fix has been pushed to the repository and firmware.bin has been updated.
I've now got a light working on pin 2.7 :-)".
so it it still corrected in the remora.c or is the fix like commented out or something like that.
I would really appreciate if you could help me out or point me in the right direction.
Huge thanks

hello everyone, I am a newbie to linuxcnc but have learn alot in the past few months.
This is my scenario: I am using W5500-EVB-Pico board as a controller for 3-axis cnc machine. Loaded with the remora firmware, followed https://github.com/jschoch/Remora-RP2040-W5500/commits?author=jschoch , and did what had to be done to get it working. The problem is that when i add outputs in the config.txt fie, it stops working. Whatever i do it just doesn't work.
The hale file:
https://github.com/scottalford75/Remora-NVEM/blob/main/LinuxCNC/ConfigSamples/remora-nvem-basic/remora-nvem.hal
The config.txt file: (The thing causing the problem)
{ "Thread": "Servo", "Type": "Digital Pin", "Comment": "light", "Pin": "GP12", "Mode": "Output", "Data Bit": 0 }
