Hi all,

I'm having a problem with the ESP-WROOM-32 .
The problem is that when I power the ESP it gives the following message.
<<" ets Jun 8 2016 00:22:57

rst:0x1 (POWERON_RESET),boot:0x21 (DOWNLOAD_BOOT(UART0/UART1/SDIO_FEI_REO_V2))
waiting for download ">>
however Esp is fool functional ,and the circuit to boot works perfectly.

I upload program via Arduino IDE with board->ESP32 Wrover Module.

does anyone know how my ESP after power on stop boot and start its program normally??

Is there something connected to GPIO0 of the ESP? If this is pulled low, the chip will go into download mode.

WROVER != WROOM.

Switch board definitions.

As for boot-up, it sounds like you are also pressing the IO0 button (boot) instead of just reset/rst. Press only ONE button, unless you are trying to upload (which you shouldn't need to press any buttons for, if your setup is working correctly).
