To answer your question snahmad75, no you cannot. To give one example, Boost uses a different threading system which is not compatible with ESP32's FreeRTOS. The project will not compile.

Hi everyone,

For my project i need to use the flash to store 2 types of information :

1. Vital configuration of my ESP32 (i.e server authentification keys, WIFI credentials and some other values...)
2. Sensor data that will be stored in flash and that will be recovered after a week of usage ...

Hi,

i am trying to use Boost library on my ESP32 and get this error on Boost files when issuing 'make' : .... error: cannot use typeid with -fno-rtti

With this command on the terminal : user@ubuntu:~$ xtensa-esp32-elf-gcc-5.2.0 -v I can see configured with
.... --enable-cxx-flags='-fno-rtti ...

So i found it. Very easy.

On the official site of Espressif (https://www.espressif.com/en/support/do ... ther-tools) you can find "ESP32 Certification and Test" and use flash tool to test your ESP32.

Hi,

For example : I solder a ESP-WROOM-32 chip on a PCB that i made, who seems to be working great afterwards (it flashes and runs code).

But I want to assure myself that the ESP32 chip was not damaged in any way during the soldering operation. To do this i think a self-test program on the ESP32 ...

@kolban :
Thank you, I now understand the usage of IRAM_ATTR, especially for the interrupts i am using. I hope this post will be useful to other people searching for this information.

@ESP_Sprite :
Interesting.

In short ; I am not using esp_intr_alloc(). That may be why I had to use IRAM_ATTR in ...

Hi,

i do not fully comprehend IRAM_ATTR. From my understanding it tells to a function to use or to be in the Internal RAM of the ESP32.

One time I used it to fix an error concerning a interrupt function running on the second core ; error which made the ESP32 crash saying there was an error with ...

Haha ! I laughed at myself ! :P

Indeed i copied and pasted it from your book (kolban-ESP32.pdf), page 990.

I fixed it and now it connects to AP with no problem.

Hey it's my error too, i should have seen it !

by the way i just want to let you know that i appreciate your work and the documentation ...

Hi. I am trying to use C++ and C on the ESP32.

-> kolban's CPP Utils (https://github.com/nkolban/esp32-snippets/tree/master/cpp_utils)

My code is simple, i used the snippet in kolban's book and i followed the readme.md (i followed instructions) :

#include "WiFi.h"

extern "C" {
void app_main ...
