Thank you, Tony. My Ai-Thinker NodeMCU-32S worked fine, and I got "MicroPython v1.8.6-567-g975df68 on 2017-02-04; ESP32 module with ESP32." The first problem I encountered was when trying to erase flash. Holding the boot button, tapping EN (reset), then releasing boot, got an error. What I had to do was hold down the boot button until the command started to work, then just release it. No tapping EN (reset) at all. I hate those small buttons so close to the usb connector. They are so difficult to use. I used the same procedure for the next step. I did it on Windows 7, so the Virtual Box screens were different than on your Mac, but easy enough to figure out.


Thanks again.

Great info. MycroPython Rocks. Keep up the great information. It is much appreciated.

[thomaskrueger]

Thanks for this very helpful video; it worked for me.

[bertieblob]

Interesting and helpful. Any chance of an updated version of this? Thanks.

[gkhan]

just wanted to say your videos are awsome!!

[dmurphydrtc]

Tony love your videos...I have a esp-wroom-32 board and when I want to flash (deploy) firmware I don't need to hit the reset/boot button combinations. Done this multiple times now. FYI.

[jimstarr]

Thank you. Wish I found this about a week earlier. Could not get a REPL working. It was exactly the qio vs dio problem (I needed to use dio as you suggested).

[MahmudIbrahim]

Great tutorial. Keep up the good work. I would ask you that How to use Adafruit MQTT library for ESp8266 in micropython??

[danieltrivino]

Many thanks for the video, Do you happen to know how to install ESP NOW using MidroPython?
Thanks in advance for your help

Daniel

[Electromaniaworld]

can we do it on any esp32 modules ? e.g. bare esp32 boards ? is there any limitation for Flash required to run micropython

It appears that the latest version of esp-idf doesn't work. If you are having problems, try checking out the correct hash as mentioned in the video.

It took me a long time to work out that was the problem :(

With any version of Linux, the reason you need to use sudo with apt-get install is to elevate yourself to super user. sudo = super user do. Unlike Windows when your login under a user account that setup as Administrator, your the Administrator every minute your login under that profile. I don't know about Mac. I'm running Ubuntu 16.04 and have tweek some of the commands you use.

[johndripper]

can someone tell me how many firmwares are there for esp32 and whats the official firmware? im so confused

[glenp]

I get this when I perform a make as the vagrant user.

In function 'bootloader_main':
error: 'CONFIG_ESP32_XTAL_FREQ' undeclared (first use in this function)
clk_cfg.xtal_freq = CONFIG_ESP32_XTAL_FREQ;

[jameshansen]

For anyone following this video, sometimes you do have to push the ESP-IDF back to the hash supported. I compile both ESP8266 and ESP32 and it runs into issues.


But essentially, grep for ESPIDF_SUPHASH in esp32/Makefile. Then:
cd /home/vagrant/esp-idf; git checkout <HASH>; git submodule update --recursive

Then you can start over with a make clean followed by make. It worked for me on Sept 1, 2017.

Thank you, Tony.
Unfortunately, despite following your clear instructions, I run into a 'make' error: "soc/soc.h" does not exists in file I've read some forums and found soc.h does exist in another esp-idf folder. However, I've no idea what to do. Could you give me a clue how to proceed? Thanks in advance. Peter

PS. I'm using an ESP32 dev.board (DoIt) with an ESP-WROOM-32. Used FLASH_MODE dio and FLASH_SIZE 4MB, but that does not seem to make any difference in the compiling with make.

Wow, looks like my interest in IOTs has landed me in a pit of angry snakes. Trying to clarify what videos work with what devices more specifically NodeMCU which I have seen it also referred to as the ESP8266. Can MicroPyhon be loaded on the NodeMCU/ESP8266?
