Hi all, I'm facing a strange issue with my esp. I know that I'm OT, but may someone alraedy faced this problem. Sometimes, when I power up the esp, the board is totally irresponsible end the small led starts to flash quickly. Even unplugging and plugging the USB connector don't solve the issue. The only solution is reflash the chip (an easy "make flash") and the esp restarts to works. The board is a Lolin v0.1. Any idea ? Maybe the flash ram starts to be corrupted?
