Frequently Asked Questions¶
How to modify an sdkconfig option in Arduino?¶
Arduino-esp32 project is based on ESP-IDF. While ESP-IDF supports configuration of various compile-time options (known as “Kconfig options” or “sdkconfig options”) via a “menuconfig” tool, this feature is not available in Arduino IDE.
To use the arduino-esp32 core with a modified sdkconfig option, you need to use ESP-IDF to compile Arduino libraries. Please see Arduino as an ESP-IDF component and Library Builder for the two solutions available.
Note that modifying
sdkconfig.h files found in the arduino-esp32 project tree does not result in changes to these options. This is because ESP-IDF libraries are included into the arduino-esp32 project tree as pre-built libraries.
How to compile libs with different debug level?¶
The short answer is
esp32-arduino-lib-builder/configs/defconfig.common:44. A guide explaining the process can be found here <guides/core_debug>
SPIFFS mount failed¶
When you come across and error like this:
E (588) SPIFFS: mount failed, -10025 [E][SPIFFS.cpp:47] begin(): Mounting SPIFFS failed! Error: -1
Try enforcing format on fail in your code by adding
true in the
begin method such as this:
See the method prototype for reference:
bool begin(bool formatOnFail=false, const char * basePath="/spiffs", uint8_t maxOpenFiles=10, const char * partitionLabel=NULL);
