ESP32 Forum

Hello.
I am trying to upload a program to ESP-Wroom-32D. I connect 3.3V, GND, RX and TX. I get into download mode (GND-GPI0) but the console says: 'rst:0x1 (POWERON_RESET),boot:0x1'
But it should be: 'rst:0x1 (POWERON_RESET),boot:0x3'
Where am I making mistake?
Thanks.

The level of the GPIO15/MTDO pin is low in your hardware while it is high in the 0x3 boot line. You should still be able to flash the ESP32, whatever the level of that pin is.

Unfortunately I can't connect to esp, no flashing.
Connecting........... and end.

I'd suggest you check the Tx line from your serial port or USB-serial converter to the Rx of the ESP32 in that case. If that's faulty, you can't get a connection.
