The conclusion is that the 5V Vcc cannot connect to 3.3V device.

The Grove's Vcc would be nice to be 3.3V as the ESP32 is powered by 3.3V. Also, the Grove socket/connector is too tight, so much so, Grove male connector will break the edge.

I gave it a go using all esp-idf components and a program without M5Stack. I then hit the command, "make flash monitor". The result is as what you said. Awesome!

I would like use your source to get the TFT LCD screen to work first. Do you have any advise for me that I should aware, avoid, etc, please?

Thank you

Did you refer to the driver or the M5Stack-idf? All my esp-idf drivers and examples as well as the Webradio Bluetooth Speaker work without any issues. Can you be more specific, please?

Has anyone encounter similar problem in Ubuntu?

I read the description of the environment it was modified CP210x driver for the 2.6.38 kernel (Ubuntu 11.04).However, I am now running Ubuntu 16.04, 4.13.0-35-generic.
See the error messages below. Is this driver still needed to program/use M5Stack. If yes, has anyone succeeded compiling it?

Hi there,
I haven't seen much information on M5Stack using esp-idf FreeRTOS. Hence, I would like to know if anyone out there using M5Stack with esp-idf which is FreeRTOS. What about those drivers, such as TFT-LCD, MPU9520, GSM, etc, are they available in esp-idf?
