Enable spindle synchronized compilation, and the firmware will crash after sending "?" about 600-1000 times. #320

For the sake of testing rigor, I re-downloaded the latest core and F4 driver source code. For the sake of testing rigor, I only enabled #define SPINDLE_SYNC_ENABLE 1 and #define BOARD_CNC3040 in my_machine.h. I tested the serial port and USB virtual serial port on both F407 and F401 respectively. For the sake of testing rigor, I only used the original serial port sending tool to send "?" every 100 milliseconds. No other commands were sent after power-on.

Testing with the spindle synchronized compilation option disabled showed no issues.

Do you have an encoder connected or are the encoder inputs floating?

Do you have an encoder connected or are the encoder inputs floating? Currently, my STM32F407 is just a development board. After flashing the firmware, it only sends "?" for testing purposes, so there is no connection to any IO pins.

I followed your advice and changed the spindle pulse to PD2. I tried connecting it to both GND and 3V3, but it still did not work. This problem may be quite challenging, so for now, I have only brought out their pins without enabling spindle synchronization in the compilation.

I have now run a F411 Blackpill with a simulator connected to the encoder pins and the spindle running (providing encoder inputs) for > 10 hours with no issues. Try with the encoder pins shorted to ground?

Even when I connect both the spindle pulse port and the spindle index to GND, the spindle still dies after a certain amount of time after power-up.

Perhaps there is nothing wrong with grblhal, and since I currently do not have a lathe for testing, I can put this problem on hold for now.
