Hello,
I have the esp 8266 01 already in use and it functions perfectly.
Now I want to use the version 07, but i can't flash the firmware.
This is my ESP on a PCB to connect it with jumper cables:
I soldered a 10k resistor between VCC and EN to enable the ESP without a jumper.
My programmer is a USBtoESP8266 (for the 01 version board):
This is the chematic i used:
Then it looks like this:
The Software i used is the CMD based "flash.cmd" whitch come with the Build 145.
I have already tried the arduino ide and other flasher, but always with the same result.
To startup the ESP I used this mapping:
PIN
VCC VCC (3.3V)
GND GND
GPIO0 PullUp
GPIO15 PullDown
CH_PD PullUp
Has Someone an idea what I make wrong or can do better?

Re: couldn't flash esp 07
I just flashed an ESP 07 today.
what I did
connected 3,3V to VCC and EN
grounded GND GPIO15 & GPIO00
flased the firmware with the provided flasher, make sure you have the correct port & flash size (1M for esp07).
hope it helps.

Hi,
I got it
Just forget resistor on reset.
Now the esp is running nicely.
