Can not flash ESP-01 (not ESP-01S)
Posted: Mon Jan 06, 2020 4:59 pm
I do have a programmer from @dyimore.cc.
Using it I can flash ESP-01S.
The ESP-01S came with a relay board.
The programmer came with a ESP-01. I also bought 5 at one time for a total of 6. I have used the programer on all 6 of the ESP-01. I have other USB serial flashers. They work on the ESP-01S, but not the ESP-01.
I did find some old articles, but they did not fit and not being sure the culture on this forum I was afraid to resurrect an old thread.
The programmer does have a switch that shorts GRD to IO0. I don't think that is my issue.
Just in case I have what I am calling the S model backward, let me ask this.
My non S models are black also, but I am sure of the 01S (right side) because it is silkscreened.
So is the one on the left an ESP-01?
Do they program the same?
Here is an example of me trying to erase the memory. Same error if I try and flash it.

After posting I found this explaining the differences between the black boards.

As you can see, mine does not have the "AI-could inside" silkscreened.

Here is a video I posted for the person who is helping me where I bought it. I load a 01S model first then the 01 model fails.

ESP-01 (blue PCB) vs ESP-01S (black PCB)
- 512kB flash vs 1MB flash
- Red power LED vs -No- power LED
- Blue LED on TX vs Blue LED on GPIO2 (low = on)
