Hi probably something stupid going on here but cant find it !
I have a bare ESP32-S3 WROOM 1 connected to a USAT/USB board. via TX0 and RX0.
if I use Putty (11520) it communicates fine giving this output when I reset it:

in the Arduino 1.8
I have this code which I attempt to upload with I00 set to 0v and "EN" briefly set to 0v
The COM port is visable as COM 8 and I have tried upload speed of 921600 and 115200.
TX0 >RX and RX0>TX
Board setting are:
firebeetle -esp32
upload speed - tried 115200 and 921600
Flash freqency 80Mhz
Core debug level none
I also have tried board type as Lolin 32 , sparkfun32, esp32s3devmodule
void setup() {
Serial.begin(115200);
}
void loop()
{
Serial.println("ESP working !!");
}
The error message is
A fatal error occurred: Failed to connect to ESP32: No serial data received.
