Core2 v1.1 wont run from mbus 5V

[HolgerRauls]

I like to power the Core2 from an RS232 base module via the MBus 5V pin. This should work by switching the MBus to Input mode as shown below. However, it seems to remain in output mode and the Core2 keeps restarting i.e. the screen flashes up about once per sec. If powered via USB the device comes up normal.

Thanks for any advice!
Holger

#include <M5Core2.h>

void setup()
{
  M5.begin(true, false, false, false, kMBusModeInput, false); 
  M5.Lcd.print("M5Core2 started");
}

void loop() 
{
}

Hello @HolgerRauls

unfortunately M5Core2 v1.1 isn't fully supported in M5Core2 library. See here.

Consider switching to M5Unified library which supports M5Core2 v1.1 to run from MBus 5V.

Thanks
