How to update ESP32 Arduino Core

Postby jscastonguay » Sun Dec 02, 2018 7:45 pm

Hello,

How can I update the ESP32 Core for Arduino IDE? In document

https://github.com/espressif/arduino-es ... windows.md

we can see the git fetch step used to update the Arduino Core. I am not sure to understand: a git fetch only got the modifications from origin to the local repository but no to the workspace. Instead, a git pull is needed. Am I wrong? If not, how to do the update?

Thanks,

JS

There are two ways
In Arduino IDE the board manager can be used to select ESP32 and update the latest 'released to Arduino" ESp32 files. These are not the latest on Github

If you use the Github then this can upload the latest version

In both cases the files are located in a hardware folder in your Arduino sketch folder. You may have to enable this during the update process

I have seen a recommendation that says you should totally delete the ESp32 folder in the hardware folder before doing either action . I have done this, moving from the Arduino version to the latest version.

This actually helped me to solve the problem with continuous reboot.

In Arduino IDE: click Tools, Board, Board Manager.
After the dialog is loaded type ESP32 and look for:
esp32 by Espressif Systems ...
if it is installed
Press Update button (in my case to version 1.0.4)
if it is not installed, I can not see how you got here to find the continuous reboot problem.
But do not worry, just press Install button.

Try this before you go for 160MHz CPU frequency, 40MHz flash, DIO flash mode, PSRAM disabled etc.
not to mention the resistor and capacitor on EN input.
