    SPI MODE should be DIO. The rest of the settings can be.

    Of course you should clean the flash every time.

    And it is not.
    .
    This is not possible in the tool. At 80MHz you can set SPI, but you don't need to, at 40MHz it works too. Rip everything into a short directory so you can see what you are uploading where.
    Set yourself up like this:
    No new access point after uploading ESPEasy_mega to ESP-WROOM-32 .
    Note if the green progress bar when uploading flies to the end, you can of course upload with baud 921kb, it is faster, but the cable must be good and short.
    After the first reset when you have the serial connected the monitor will spit it out:

    What "adapter" are you using to program this module?

    I was referring to the "adapter" for the ESP32 module itself and how it connects to the USB/UART converter along with the power supply.

    Upload using Arduino IDE + ESP32 CORE some example with led flashing or printing something on the UART. If the chip works OK without wifi, then it probably has power supply issues.
    I would blindly start with the capacitor at the chip itself, a small ceramic 100nF to start with, and end up somewhere around 3000uF. I've had the problem a few times with modules going OK, but only when I'm not using WIFI. You can see from the log that it randomly bushes somewhere in between:

    Check that there are not two resistors missing there, as in the diagram below - the LED with a series resistor can be given up.

    Of course, the 3.3V supply and the USB/UART converter must also be switched to 3V3 mode.

    The adapter is similar, but there is no LED.

    I raised the supply voltage, to 4.2V and it started up

    And is it definitely 4.2V on the ESP supply now?

    I soldered these resistors myself because they were not available
    Now I have set 4.4V and the module draws about 140 mA and surprisingly it works

    These are my monsters:

    I added 1000uF to the pure module to get the WIFI working, and 3300uF to the Lolin32, connecting the battery did nothing. I just happened to get this one for free from a Chinese guy because he was supposed to send something else, so I'm not complaining. Both worked beautifully until I turned on the WIFI. Pre-made boards with ESP32 rarely have problems, but as you can see it happens.

    I have doubts about measuring this voltage.
    The ESP32-WROOM-32 should be running at 2.7V~3.6V. It consumes 80 mA on average, at peak it can be up to 500 mA.
    There is no need to "stick" electrolytic capacitors on the ESP32 power supply, as long as the power supply itself has sufficient current capacity, i.e. min. 500 mA and "holds" the required voltage at this load (e.g. some USB ports may not meet these requirements). If you supply this ESP32 with more than 4V, you will simply shorten its lifetime.

    I am powering this with a laboratory power supply from KORAD.
    I added a capacitor, but it did not change anything.
    Strange situation with this power supply. if I set it to 3.3V the current consumption is only 40mA and of course it does not connect to the router

    Can you verify the voltage measurement with some sort of meter?

    I found the cause
    I added wires to the ESP adapter.... Previously I had such small connectors for golpins and there was a big voltage drop on them (poor connection). Now I have 3.5V on the power supply and 3.48 on the meter at the adapter.

    Hello again. I would like to revisit the topic of esp32. Namely, I am trying to upload a file named "ESP_Easy_mega_20211105_normal_ESP32_4M316k" from github.com in cell 0x10000 but unfortunately after uploading, ESP does not send out AP. How to do this?

Topic summary

The discussion revolves around issues faced when uploading the ESPEasy_mega firmware to the ESP-WROOM-32 module. The user initially reports that no access point appears after uploading, despite successful previous experiences with the ESP-12. Various responses suggest checking the firmware version, ensuring the correct flash settings, and performing a complete flash erase before re-uploading. Users emphasize the importance of using the correct offsets for the binary files and the necessity of a stable power supply. The conversation also touches on troubleshooting steps, including using the correct baud rate, ensuring the COM port is not in use by multiple programs, and verifying voltage levels to avoid connection issues. Ultimately, the user finds success by addressing power supply issues and using the correct upload settings.
