That might be why the iFan03 I flashed with Tasmota was so finicky trying to get it to flash. I believe it’s running on an ESP8285. That does kind of explain it.
How to you reset while holding down IO0 and having the board plugged in? For the life of me I can’t seem to be able to flash a sonoff 4ch
Never, ever flash a board with it pugged into mains power.
At best you will fry your PC. At worst, yourself.
That did the job! Thanks a lot!
Spend 2 hours trying to flash ESP WROOM 32
Hello there, I’m facing the kinda the same problem, except that I’m using a Esp32-cam
(ESP-32s)
And I’m using a USB ESP-01 module. connecting (as you can see in the next pictures)
U0R -Tx
U0T - Rx
GND -GND
VCC- 3.3V
Trying to imitate an FTDI interface like this:
But I get the same mistake:
Unexpected error: ESP Chip Auto-Detection failed: Failed to connect to Espressif device: Timed out waiting for packet header
But this module, the ESP-32 cam, just have one button: RST button, it flashes while I press, but I cant upload any code and I always get the same error.
Any ideas?
I figured it out, with ESP-01 USB adapters you need to connect Tx-Tx and Rx-Rx… I’ll explain more here:
