Problems getting program to run.

Hi, please be gentle with me on this one. This is my first post and I’m very new to D1 mini’s.
I’m trying to construct a Automatic Blind controller that I found on the internet. I’ve made all the hardware but I’m getting stuck trying to run the program. it’s supposed to connect to Blynk, also Alexa.

It’s running from a D1 mini plugged into a DC power shield, with a PCB board mounted on top of these.

I can install the program without and problem but when loaded the board seems to keep on rebooting, checking the serial monitor I keep on getting this report every few seconds and the blue LED flashes

ets Jan 8 2013,rst cause:2, boot mode:(3,7)

load 0x4010f000, len 1392, room 16
tail 0
chksum 0xd0
csum 0xd0

Can anyone explain what it all means and how i can fix it.

I’ve uploaded other programs using Blynk which appear to work ok, so i don’t think its the D1 mini thats at fault.


Perhaps it’s the fault of the code you didn’t post.
