Hi,

I got a strange problem with esp32-wrover-e. I have uploaded a simple code which should just printing out a text message (in loop method). And while I am uploading, compiling.. and it is restarting by itself everything is fine.. program is working as expected.. but when I plugged out the power supply or usb and plugged in again I noticed that esp is not starting untill I press EN/RST button on esp..
I tested on two of esp32-wrover-e and the result is the same.
Could you help me with that?

regards,
chris

I just want to mention this is an esp32-wrover-dev. So it doesn't need to add 1uF capacitor and 10k resistor in circuit near 3.3/EN/GND.
Actually, I also tried with RC but it didn't change anything (should be implemented already in DEV boards).
