Issues flashing brand new ESP32 Module

[dgube1]

So I'm trying to create my own development board for the ESP32, when trying to flash the boards I couldn't get the module to enter bootloader mode, at first I assumed it was my design so I wired up a single module seperate from my design and still could not get the module to enter bootloader mode and program. This issue occurs both for the MingW32 environment and in Arduino has anyone had a similar issue?

I'm using an FT232 as a usb-uart bridge to program with buttons attached to GPIO0 and EN for initiating bootloader mode but no luck so far.

GPIO2 should be low, when booting ESP32 in UART mode. Please check this point first.

To flash, you need to enter into the bootloader. Here is the wiki on that https://github.com/espressif/esptool/wi ... -Selection.

I recently wrote a GUI to connect and flash ESP32. https://github.com/sunbearc22/ESP32FlashWriter. I have tested it on Linux (Ubuntu 16.04) and Windows 10 with a ESP32 DevKitV1 board. I wonder if this can help you?

Will pressing EN and GPIO0 buttons can make the board into downlaod mode?
