ESP32-LyraT-Mini: Blink example doesn't start unless pressing RESET button

Postby hackson » Mon May 11, 2020 3:34 pm

Hello,
I just bought an ESP32-LyraT-Mini board and flashed the blink example program under esp-idf repository. When the board is connected to the host computer via usb and running by "make flash monitor" command, the blinking function works fine. But when I use the board alone, plug in the micro usb cable to the power slot with POWER SWITCH - ON, the board is "idle" and doesn't blink. After manually pressing the RESET button, it starts blinking.

Here is the demo video: https://drive.google.com/file/d/1OFcvq2 ... sp=sharing

My question is: is this a correct behavior, or did I miss anything? How to make it running as soon as I plug in a power micro usb cable? Thanks.
