ESP-IDF on Ubuntu 20.04.1

This is commands used in youtube video

Commands:

sudo apt update && sudo apt upgrade -y

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1

sudo apt install -y python3-pip

sudo update-alternatives --install /usr/bin/pip pip /usr/bin/pip3 1

sudo apt install -y git wget flex bison gperf python-setuptools cmake ninja-build ccache libffi-dev libssl-dev dfu-util

cd ~

mkdir esp

cd esp

git clone --recursive https://github.com/espressif/esp-idf.git

cd esp-idf

. ./install.sh

pip install --upgrade pip

. ./export.sh

nano ~/.profile

Append next line to ~/.profile script:

. $HOME/esp/esp-idf/export.sh

To save press CTRL+X, Y, ENTER

sudo usermod -a -G dialout,tty $USER

Restart machine. If you are on virtual machine then shutdown completely and start it again.

ls /dev/ttyUSB*

cd ~/Desktop

cp -r $IDF_PATH/examples/get-started/hello_world .

cd hello_world

idf.py set-target esp32

idf.py menuconfig

idf.py build

Put ESP32 into programming mode.

idf.py -p /dev/ttyUSB0 flash

idf.py monitor

To exit monitor press CTRL+]

Very helpful. Missed the update-alternatives step and couldn't figure out why it was crying about python2

when installing all necessary tools you miss typed a package. Its python-setuptoolsnot python-serialtools

Thank you @fmillerr 👍, it's fixed.

Hi, thanks a lot for this tutorial, it is very useful for beginners like me 👍
I am stuck when flashing. Could you help me please ?

Here is the error message and logs :

Hi @Sphaaax

Hi.

I think
. ./export.sh

-->

source ./export.sh

run export.sh doesn't work for me. only source works

Hi @buildorder

. ./export.sh is same as source ./export.sh

You can notice that there is dot and space at the beginning of . ./export.sh command.
On the first image you have executed ./export.sh instead of . ./export.sh

I'm using the Adafruit esp32 feather huzzah and had to include baud rate that's different from the default in order to flash.

https://cdn-learn.adafruit.com/downloads/pdf/adafruit-huzzah32-esp32-feather.pdf
According to the datasheet, they recommend 921600

The command would then be:
idf.py -p /dev/ttyS8 -b 921600 flash monitor

Hello, first thanks for the tutorial ! I tried different tutorials to do that during more than a week and none of them worked for me, but yours worker so thanks a lot !

But now, I'd like to flash an existing project namely the AT-command firmware : https://github.com/espressif/esp-at but I have absolutly no idea on how to do that, I tried the method explained there : https://docs.espressif.com/projects/esp-at/en/release-v2.2.0.0_esp32c3/Compile_and_Develop/How_to_clone_project_and_compile_it.html but I got errors.

Do you have any idea on how to do that ?

Hi thanks for step by step explanation but I am not able to come out of monitor. please help

Hi,
Amazing video - thanks a lot.

I want to share what was not working in my case:
. ./install.sh causing terminal crash, works with
chmod +x install.sh
and
flashing return error related, the solution was pressing BOOT button and executing idf.py -p /dev/ttyUSB0 flash
and
idf.py monitor return error, works with
idf.py monitor -p /dev/ttyUSB0

issues are probably related to my setup (Ubuntu VM on Parallels + ES-WROOM-32)

Thank you @kampi0

When doing "ls /dev/ttyUSB*" I get: "ls: cannot access '/dev/ttyUSB': No such file or directory".

If doing "ls /dev/tty*": there none close even to ttyUSB. It seems the OS lacks the drivers to work on. So I downloaded the following: Linux 3.x.x/4.x.x/5.x.x VCP Driver

Well, when I do 'make' for installing, it, I get errors and, so far, no good (have tried a lot online):
