#73869 Hi,

I have 2 x esp8266-01s that I can programming without an issie.

But I also have 3 x esp8266-01 and they just don't work.
I can't program them nor can I get anything in the serial monitor whatever I do.

What can I try? I don't believe they are all dead on arrivals :(
I have a FTDI with 3,3V out and connected DTR -> GPIO0 and RTS -> RST
I also tried with a separate 3,3V supply.
