Serial2 recieve garbage when SPI device conected

[Gargantuanman]

What you are trying to do?
Use all 3 serial ports, the Serial1 is mapped to pin 13 and 14. and Serial0 and 2 are standard mapped.

Hardware:

Board: node32
Core Installation version: 1.0.4
IDE name: Arduino IDE
Flash Frequency: 80Mhz
PSRAM enabled: ?no? ?yes?
Upload Speed: 115200
Computer OS: Windows 10

Description:

Hello, I'm trying to use all 3 serial ports with the following code, I have been using this code, and worked perfectly, but today I connected an SPI Ethernet module that doesn't use any of the Serial pins but simply having the SPI device connected make Serial2 receive a lot of garbage. I checked the PCB and there are no hardware issues no short circuits or similar, If I Unplug the SPI module Serial works flawlessly, but if connected garbage returns only to Serial 2. I have look for a ESP32 limitation but havent found if that's the case.

Ethernet Module uses the following pins:
MISO 19
MOSI 23
ClK 18
Reset 26
CS 5

Sketch:

//Change the code below by your sketch
void setup() {
  Serial.begin(115200);
  Serial1.begin(57600, SERIAL_8N1, 13, 14);
  Serial2.begin(57600, SERIAL_8N1, 16, 17); //Serial2.begin(57600); I used like this originally

}

void loop() {

  if (Serial1.available()) {
    Serial.write(Serial1.read());
  }

  if (Serial2.available()) {
    Serial.write(Serial2.read());
  }
}

By coincidence or not, pins 13 and 14 are default HSPI MOSI and CLK.
Arduino SPI default pins are HSPI pins (12, 13, 14 and 15)

Try using other pins for Serial1.
By the way, you can use default Serial1 pins since you set Arduino Flash Mode to DIO in the menu.

Thank you, I found that an unused reset pin connected to GPIO26 seems to be the one causing the trouble, I don't actually know why but now is working, also I think I will change from 13 14 to 26 27 that actually where the pins I originally used now that I know i don't require the hardware reset of Module.
