Dear All,
I made a custom board using ESP32-WROOM-32. I was testing with a "Hello World" program. During programming, I got the following in the output tab
Sketch uses 260193 bytes (19%) of program storage space. Maximum is 1310720 bytes.
Global variables use 21344 bytes (6%) of dynamic memory, leaving 306336 bytes for local variables. Maximum is 327680 bytes.
esptool.py v4.5.1
Serial port COM3
Connecting.....
Chip is ESP32-D0WDQ6 (revision v1.0)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
Crystal is 40MHz

Hard resetting via RTS pin...
The code I have used is
void setup()
{
Serial.begin(9600);
}
void loop()
{
Serial.println("Hello World!");
}
No legible output is seen in Serial Monitor.

When i short the Boot Pin to GND, then again some illegible output comes
What could be the issue? Is the ESP32 damaged or is there some other issue?
