Hi!
What fails, the flashing progress, the lights and/or the WLED-AP showing up? What is your flasher program?
The partition layout is only setup to use 4mb, but it should run fine on 16mb units. Have you tried erasing the flash?
Hope we can get it to work! :)

Hi Aircoookie !
Thanks for your answer. I hope so too :)

Flashing the ESP32 is done by flash_download_tool_v3.8.5
Settings are : SPI SPEED = 40Mhz ; SPI MODE = DIO ; Flash Size = 128Mbit ;
esp32_bootloader.bin at 0x00000 and WLED_0.11.1_ESP32.bin at 0x10000
I always click ERASE befor flashing. ;)

The flash-procedure is done with no errors , but after restarting the device the bootlog says : Waiting for download
It seems that the device didn't find a firmare on the flashchip and boots into flash-mode.

The second device i have , has a 32Mbit flash , with the same settings but FLASH-SIZE = 32Mbit , the ESP32 boots the WLED-Firmware.

What is going wrong ? What can i do ?

Hi !
I have got it working .
Flashing was easy , if you know it :) ( Google was my friend , but hard for me to find )

My steps :

1. Erasing the flashchip
2. In the flash_download_tool_v3.8.5 there is a folder named "** bin **". In this folder there are four binaries named _a_0x1000.bin , _b_0x8000.bin , _c_0x10000.bin and _d_0x225000.bin . I think the four binaries a,b,c,d are for initial-flashing.
3. Setting the flash address of the files : for _a_0x1000.bin set to 0x1000 , and so on.
4. Then i flashed the four files.
5. After flashing i set the esp32_bootloader.bin to 0x00000 and the WLED-firmware WLED_0.11.1_ESP32.bin to 0x10000
6. Flashed these two files , did a reset on the ESP32 board and the firmware was booting . :)

Now the ESP32 Board with the W25Q128 (16Mb) is working without any Problems.

Thanks for help ,
