Introduction and AAARRRRRRRGGGGGG!!!! Trying to get ESP-12 for EspruinoWiFi Flashed with Correct Firmware.

Hello Gordon, thank you for your reply.

My apologies, but I think my previous post was not entirely clear and complete based on a couple of things in your reply. (I have not modified the boot loader and A15 should already be tied low per your design)

The board I am attempting to build is essentially an exact copy of the official EspruinoWiFi built from the Eagle files you have made available and running the latest version of Espruino software updated via the IDE.

Now, onto my issues attempting to flash the ESP-12 module through the EspruinoWiFi board.

I had read the following instructions and forum post in an attempt to see if it would work on the EspruinoWiFi board:

and

In the linked forum post, the user soldered wires to RX/TX on the onboard ESP module and I would prefer to avoid that if possible.

I am actually running the code shown in my previous post on the officially purchased board as a “proof of concept”. Board is connected to the IDE, code shown is pasted into the left side of the IDE and certainly seems to execute as written, disconnect button on IDE is pressed, and then I issue the following command on my PC:

esptool.py -p COM7 -b 115200 flash_id

My thinking is that if the non-destructive flash_id command works, then the write_flash command should also work.

I hope am making some sense.

Thanks again.

Dale

p.s. I finally managed to get the AT firmware flashed onto my leadless, unmounted ESP-12S module so none of the above is any way a show stopper.
