ColorCNC Colorlight 5A-75E/5A-75B as FPGA controller board

Did you post it in the previous post, I saw it in the previous post

Did you post it in the previous post, I saw it in the previous post，I tested it with a servo motor connected to J9-1 and J9-2 last night. I tried both the speed mode and the position mode of the servo. The motor does not turn, and then I use the stepper motor to go to the pulse mode, but it doesn’t work. J9-1 and J9-2 run the code to measure the voltage change。Use your default configuration in the hal example，There is another question I would like to ask you. I use the USB BLASTER to flash the firmware. The command is openFPGALoader -c usb-blaster -m, but I have to flash the firmware again after power off. Can it be permanent?

The option for flashing in the eeprom is -f, I'm using this command:
openFPGALoader --unprotect-flash -c ft232 -f Lcnc.bit

So if I remember correctly, J9-1 and J9-2 are step and direction of stepgen zero for your confiiguration.
Do you have a multimeter to check if the board is geenrating any voltage on these pins?
I would start with the simplest configuration possible:
Use HAL.hal in support files, use halshow to check the pins status and set them manually. Start first with the board enabling sequence, as expained in the readme, then adde all the pins and parameters of the stepgen 0 and if everything is right once you set the velocity command to a value other than zero you should see the position feedback in halshow change and see the pulses on the pins. If there are no pulses but the position is changing then maybe there is some problem in your pin mapping.

The voltage of J9-1 only fluctuates by 1-2V, and J9-2 will fluctuate by 3-6V. Because the power supply I use is 6.2V, it will only be generated when running the code. I tested it in jog mode, and J9- 1 and J9-2 are the Z axis, J9-3 and J9-5 are the Y axis, 67 is the X axis

It's ready to run. It's my wiring problem

I tested it. When running the code, I found that the value of the G54 coordinates will always be offset by 0.01, sometimes it will become larger and sometimes it will be smaller.
