IDF component include missing

[jomi26@gmail.com]

Hi,

I am new to ESP32 and the IDF tools so I guess I am making a rookie mistake here but I cannot figure it out and the forum search function doesnt work right now (at least for me)
I am using IDF 4.1

Here is my problem:
1. When I include esp_spi_flash.h in main.c everything compiles fine
2. When I create a new component and include esp_spi_flash.h the compilation fails.

Looking at the error in the terminal I can see that the include path to the IDF tools folder where esp_spi_flash.h is located is missing. I guess I just need to change that and it should work but how can I do that?

Below is the error message which does not include the path to esp_spi_flash.h

Hi Chegewara,

thank you for your quick reply. It works now!

I added "REQUIRES spi_flash" to the CMake file and it works.

Thank you for your help!
