Flashing difficulties with wt32-eth01

[Mitko939]

Hi,
I have a problem to flash wt32-eth01 (v1.2) with tasmota. I tryed the tasmota web installer on Chrome, but i haven't find a tasmota32 version. I try with a simple tasmota version and for one time it works. I had rebooted the wt-32 but i can't find it like AP with wifi.
I conncet from the FT232TL to W32-eth01
GND-->GND
3.3v-->3.3v
TXD-->TX0
RXD-->TX0
and only on the power on of the device the w32-eth01 GND to IO0.
I tryed much time to flash with tasmota, but now it's impossible to put the tasmota on wt32-eth01. Some advice?

I tryed flash via esp_flasher, but on mac the flasher not works ( when i open the program, this turn off itself).
What can i do? Thank you.

Swap tx and rx. It does not work if both tries to transmit on the same pins.

Note that FT232TL is generally not a good one for flashing, as it cannot deliver sufficient power for reliable flashing. And ESP32 takes more power than ESP8266.

thanks for the quick answer. I was wrong to write. links are like that:
GND-->GND
3.3v-->3.3v
TXD-->RX0
RXD-->TX0

Do you raccomand to try to power the WT32 externaly with 5V when i flash it?

[ascillato2]

5V will burn it. Do Not apply 5V to a 3.3V device. Please, use 3.3V in a 3.3V device.

[Mitko939]

the wt32-eth01 has 3.3v port and the 5v port. I powered it with 5v on 5v port. On the manual it says that you can power the wt32-eth01 with 3.3v on the pin 3.3v or with 5v on the pin 5v.
this is the manual.

Hi, I also have a problem to find the correct firmware...while reading the closed post #9496 i tried to flash via webinstaller the latest tasmota versio but finally had o ethernet config.
So i have a tasmota on the W32-S1, but need now to flash the correct one!
I need the neopool packages on it.. so i think i have to compile it in some way... - i already did it last year for normal esp32... - have to enter again how i did it. i think i did it with gitpod... so i have to find a working wt32 tasmota and integrate neopool... maybe someone has some hints...

The Ethernet support is by default included in ESP32 builds, without you needing to do anything to include it when you build. You still need to configure gpio pins and a few settings to match the hardware.
