Display Module 13.2 with PoE BASE (v12)

BTSPERTH

Hey I have the Display Module 13.2, and whilst I have gotten the output to work, I can't get ethernet to work at the same time. If I fire up ethernet at the start of sketch it is all working, but as soon as I run this command "M5.begin(cfg);" to start the display, ethernet no longer has IP address and no longer functions.

Any help appreciated.

#include <Arduino.h>
#include <M5ModuleDisplay.h>
#include <M5Unified.h>
#include <SPI.h>
#include <Ethernet2.h>
#define SCK 18
#define MISO 19
#define MOSI 23
#define CS 26

byte mac[] = { 0xAA, 0x4D, 0xBE, 0xEF, 0xFE, 0xED };
int udpPort = 9090;

void setup() {
auto cfg = M5.config();

SPI.begin(SCK, MISO, MOSI, -1);
Ethernet.init(CS);
Ethernet.begin(mac);

Serial.begin(115200); // Initialize serial communication
Serial.println(" ");
Serial.print("Local IP ");
Serial.println(Ethernet.localIP());
Serial.print("Gateway ");
Serial.println(Ethernet.gatewayIP());

cfg.external_speaker.module_display = true;
cfg.external_display.module_display = true;

Serial.println(" ");
Serial.print("Local IP ");
Serial.println(Ethernet.localIP());
Serial.print("Gateway ");
Serial.println(Ethernet.gatewayIP());

// If you want to change the resolution, uncomment the following lines and
// adjust the values
  cfg.module_display.logical_width = 640;
  cfg.module_display.logical_height = 360;
  cfg.module_display.refresh_rate = 50;

Serial.println(" ");
Serial.print("Local IP ");
Serial.println(Ethernet.localIP());
Serial.print("Gateway ");
Serial.println(Ethernet.gatewayIP());

M5.begin(cfg);

Serial.println(" ");
Serial.print("Local IP ");
Serial.println(Ethernet.localIP());
Serial.print("Gateway ");
Serial.println(Ethernet.gatewayIP());

Hello @BTSPERTH

the display module schematic shows GPIO26 - BUS_G26 - F_G26 connected to BANK1 which would mean there is a conflict with Ethernet CS.

Thanks
