Did someone get these three components running together? My ESP32 just gets restarted all the time.

You better post schematics and code.

I've got it running without restarting now, but the stepper still doesn't spin. I'm getting all 0 in the Serial console. The wiring is described in the code below.

#include <WiFi.h>

#include <TMCStepper.h>

// TMC2209 GND goes to ESP32 GND
// TMC2209 VM goes to ESP32 5V
// TMC2209 VIO goes to ESP32 5V
// TMC2209 A1, A2, B1 and B2 go to NEMA 8 5V bipolar stepper coils: A: red and blue, B: green and black

// #define EN_PIN  7  // Enable pin - not needed, TMC2209 EN pin is grounded
#define DIR_PIN 2  // Direction pin
#define STEP_PIN 3 // Step pin
#define SERIAL_PORT Serial2  // GPIO 16 goes to TMC2209 pin RX, GPIO 17 goes to TMC2209 pin TX
#define DRIVER_ADDRESS 0b00 // TMC2209 Driver address
#define R_SENSE 0.11f // Sense resistor value

TMC2209Stepper driver (&SERIAL_PORT, R_SENSE, DRIVER_ADDRESS);


void setup () {
    Serial.begin (115200);

     // pinMode (EN_PIN, OUTPUT);
     // digitalWrite (EN_PIN, LOW); // Enable driver in hardware
     pinMode (DIR_PIN, OUTPUT);
     pinMode (STEP_PIN, OUTPUT);

     SERIAL_PORT.begin (115200); // Initialize UART
     driver.begin (); // Initialize driver
     driver.toff (5); // Enable driver

     driver.rms_current (800); // Set motor current
     driver.microsteps (16); // Set microstepping
}

void loop () {

    digitalWrite (DIR_PIN, HIGH); // Set direction 
    digitalWrite (STEP_PIN, HIGH); // Step delay (10); 
    digitalWrite (STEP_PIN, LOW); 
    delay (10);      

     // Read and print diagnostics
     Serial.print ("SG_RESULT: ");
     Serial.println (driver.SG_RESULT(), DEC);

    // Read DRV_STATUS 
    uint32_t status = driver.DRV_STATUS (); 
    Serial.print ("DRV_STATUS: 0x"); 
    Serial.println (status, HEX);
}

Result:

DRV_STATUS: 0x0
SG_RESULT: 0
DRV_STATUS: 0x0
SG_RESULT: 0
DRV_STATUS: 0x0
SG_RESULT: 0

It seems that for some reason I can not establish UART communication with TMC2209. I guess I'll just buy TMC2208 instead.
