Solved

I have been using a Laboratory grade power supply with constant voltage at 3.3V.
After some 4 days of messing around and frustration I decided to put a 22uF electrolytic cap and a 0.2uF Tantalanium cap across the supply and straight away I had no problems.

I hadn't bothered with these before as it was a Laboratory grade supply.

Oh well live and learn

Cheers and thanks to all

After flashing a couple of Esp-01 I decided to see if they worked in my project and yes they were great.
Went bank to flash the other two and Lo and behold , backed to where I started.

Yesterday I had to restore my win10 laptop back to an earlier version as the last update hangs at 32% due to driver issues. Since then I could flash Ok it seems.

When I tested my project based on a arduino Uno it required a driver update to work and that was just before my old problems returned.

I am thinking the issue is Win 10 or a driver or even my laptop. I will try an older computer and see how that goes.

Used a different computer and changed usb to serial module and it worked.
It still doesn't seem robust as it sometimes locks up.
Changed the advanced settings to allow more latency, not sure this had an effect.

Anyway I am up and working and my project is working

Cheers
