ESP32 Forum

Hi everyone!

I have developed a custom board with the ESP32-D0WD-V3.. I copy exactly the design from the wrover module... But I just use a 16MB flash...

I can program the system perfectly with the Arduino IDE ... But when I open the serial monitor it looks like an endless reset loop.... I can not find any hardware issue... I am very very lost...

Have you ever seen something like that?

Thank you so much in advance for your help!

Best regards!

Can you post the text that appears on the reset loop here? Also, just in case, can you post your schematic?

Did you try to flash simple empty sketch to see if its hardware or software?
