Can't flash ESP32 on Ubuntu VirtualBox

Postby SteaLTH_INSteaD » Tue Oct 27, 2020 3:54 am

Hi,

I can't seem to flash ESP32-DevKitC on the VirtualBox with Windows 10 as the Host Machine and Ubuntu 20.04.1 as the Guest Machine after following multiple guides, including this one:
https://docs.espressif.com/projects/esp ... ction.html



After plugging/unplugging the ESP32 and typing the command

Code: Select all

ls /dev/tty*
I see /dev/ttyUSB0 appear.
I see a black terminal when I try to connect with PuTTy, but nothing happens when I restart the ESP32 chip by pressing EN.

When I try to flash the device with

Code: Select all

idf.py -p /dev/ttyUSB0 -b 115200 flash
it says timed out waiting for packet header even if I hold down the Boot button.

I have tried typing

Code: Select all

dmesg | grep tty
which shows the following output

Code: Select all

cp210x converter now attached to ttyUSB0
Here are the settings for my Ubuntu virtual box. Any Ideas?

I tried next morning and it seems to be working now on ttyS1 instead of ttyUSB0!
My guess is that it should be ttyS instead of ttyUSB since it's Serial instead of USB even though it's connected to the USB port.

If I am not wrong, there should be a menuconfig option for the port configuration...
