Is your feature request related to a problem?
Hi,
I would like to ask about possibilty of using flags like CONFIG_SPIRAM_XIP_FROM_PSRAM, CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY, CONFIG_SPIRAM_ALLOW_NOINIT_SEG_EXTERNAL_MEMORY in aArduino Core projects?
Does it really requires recompiling IDF?
Regards,
Lucas

Does it really requires recompiling IDF?
Yes, ESP32 Arduino has all the IDF components precompiled based on a specific sdkconfig setting.
It is done using a tool called ESP32 Arduino Lib Builder
The main script build.sh --help prints its options and usage. It is possible to add CONFIG_SPIRAM_XIP_FROM_PSRAM=y to the configuration modifying the content of the generic sdkconfig

There is a second way to enable CONFIG_SPIRAM_XIP_FROM_PSRAM which is by building the Arduino Application using Arduino as an IDF Component. In that case, the sketch and the Arduno Core code are part of a regular IDF Project and it is possible to use idf.py menuconfig to browse and change any sdkconfig setting.
