What am I doing wrong with the ESP32 module?

Hello everyone!

I'm trying to use ESP32 but the ESP_EASY network does not appear for me to connect to 192.168.4.1.

I am using the latest mega-20181214 version and used the two programs that come in it ...

I programmed using the commands below:

esptool -p / dev / ttyUSB0 write_flash 0x00000 ESP_Easy_mega-20181214_esp32test_1M8_partition.bin

esptool -p / dev / ttyUSB0 write_flash 0x00000 ESP_Easy_mega-20181214_esp32dev.bin

The two modules are as follows:

Nothing happened, so I connected the serial and a message appears below:

What am I doing wrong? :?:

Best regards

ESP32 support is still experimental and we are very pressured by the release of a first stable for the ESP82XX. Please be patient and we'll get going on the ESP32 in early next year.

i just flashed ESPEasy_mega-20181218.zip without any problems.

I think perhaps you neglected to flash the extra bin files :
  • boot_app0.bin
  • bootloader.bin
  • ESPEasy.ino.partitions.bin

I neglected to flash the extra bin, but how you program...
See considering the latest version "Release mega-20181218" I download zip and inside has only 2 file about ESP32 ...

• boot_app0.bin → may be ESP_Easy_mega-20181218_esp32dev.bin
• bootloader.bin → :?:
• ESPEasy.ino.partitions.bin → may be ESP_Easy_mega-20181218_esp32test_1M8_partition.bin

Then a try the comand bellow:
esptool -p /dev/ttyUSB0 --baud 115200 write_flash --flash_freq 40m 0x1000 ESP_Easy_mega-20181218_esp32dev.bin

esptool.py v2.1

Please, how you program your ESP32?

Is it still a problem when flashing the latest nightly built ESP32 files?
I only flashed them using the programming environment.

Yes, that would be great.

I have an esp32 here and just for fun i would love to flash espeasy to it.

But it wont work for me, so i would need a kinda "How to flash esp32 firmware in a few steps"

So if you have a little "How to" let me know :)

Thank you so much :)

I'd really like some advice how to flash an ESP32.
Sadly I have no clue how to do that.
I could write a wiki about that but at this time my job
takes every minute so I lack time to find out everything by myself.

I've some ESP32-nodeMCUs here waiting......

I only flashed them using the programmer environment and that one is using esptool.py to flash.

so do i have to connect gpio0 and gpio2 to GND to enter boot mode so i can flash espeasy ?

Depends on the setup.
Some boards use the "node MCU" way of restart to flash mode.
This is also supported in the esptool.py flasher as reset option.
At least GPIO-0 should be held low at boot to enter flash mode.

Thank you for your answere :)

maybe i should wait untill there is an easy way to flash.

now i would say i have an "half" operating system on my ESP32.

I did use the "ESP.Easy.Flasher.exe" to flash the esp32_Test build.
(gpio0 and gpio2 where LOW)

After that an ESP is showing up as Wifi AP, i can connect, but when i try to open 192.168.4.1 nothing apears :(

When i type "ipconfig" in cmd it shows my laptop has got the 192.168.4.2 and the gateway is 192.168.4.1
So this should be fine i think

Well if you flashed it, then it should also accept commands from serial.
So you could set the SSID and password using any serial terminal, or even the ESPEasy flasher.
See: https://espeasy.readthedocs.io/en/lates ... nds-listed
wifikey and wifissid.

Testing will be lonely when there is no HowTo for flashing...
I gave in meanwhile, didn't get any ESP32 to run.
