ESP32 Can't compile

[Alan_37]

Hi I have this problem when trying to compile toolchains are installed and also esp-idf
this was working some time ago now it's not.

Anyone can help please?

Could you try the following ...

Run a Command Prompt
cd to the esp-idf directory, possibly at C:\Users\alanc\Desktop\esp-idf
e.g.

Code: Select all

cd C:\Users\alanc\Desktop\esp-idf

Then type/run

Code: Select all

install.bat esp32

Looks like a Python problem.
Only thing I can suggest is uninstalling Python, then try again.

[Alan_37]

hi, I have uninstalled everything and reinstalled it again now compiling and downloading ok

but the esp is not booting it is panic and reboot by itself I am using ESP32s any idea what can be causing this.

This is what I get from the serial port from the ESP maybe can help to understand the problem.

Rebooting...

[LeighM]

Could you attach your program?
Then we'll see if someone has an ESP32S to try it on.
Did you try a simple LED flash program?

[Alan_37]

Good morning,

I am just trying to blink an LED for now on pin 11 ( GPIO 35 ) that's all .

[LeighM]

I think we've caused some confusion by using the word "pin"
Pin 11 = A.11 = GPIO11

Another thing to consider.. GPIO35 is input only, so we can't swap to that

To determine an available output to drive the LED I will need to dig out info on this AI ESP32S board,
unless you get there first

edit: try a bit further down on GPIO25 (Pin 25, A.25)

[LeighM]

There is a very important note here ...
https://docs.espressif.com/projects/esp ... /gpio.html

Which includes ...

• SPI0/1: GPIO6-11 and GPIO16-17 are usually connected to the SPI flash and PSRAM integrated on the module and therefore should not be used for other purposes.

• GPI: GPIO34-39 can only be set as input mode and do not have software-enabled pullup or pulldown functions.

[Alan_37]

Hi LeighM ,

Yes, that was the problem, output on GPIO25 the ESP does not panic and working fine now.
I didn't know that some pins will cause the ESP to panic and reboot if set to output.
would be a good idea to disable those pins in the output icon.

And yes it would be less confusing if the pins were labeled GPIO instead of pin .

Thanks for your help LeighM.
