Stuck in bootloop

[jmccoy555]

Hello, any ideas would save my sanity!!!

Some times this works wonderfully, other I get stuck in a bootloop, serial output;

I've edited the code to use a Adafruit_ST7735 1.44" display, but that's all.

A successful boot looks like this;

My only observation is that this tends to happen more with different power supplies, but that's not consistent either. I have check all voltages are the same, and there's plenty of current, max draw when it works is only 320mA.

Thanks.

I also ran in to this when I started paring down the code to run a little faster. Using Robotdyne mega clone. I added a short delay during the loop initializing all the pins. Can't explain it more than that.
