I have an Arduiuno framework based project for an ESP32 S3 based LCD/TFT 4.3" board.
There is a slight jerk of the image on the screen durng rendering, and it looks like its been fixed using a Bounce Buffer, but only in the espressif framework not the Arduino.
Rather than port the bounce buffer to the Arduino framework, I thought I would move my entire project to use the
framework = espidf
instead, then I can just take the existnig bounce code and my code and use it.
I can compile the code, but when I upload it to the board, it fails to run, and the UART log is showing me this message
(Note that I am using the same settings in the platform io as I use for the Arduino project apart from the line
framework=espidf

**I (36) boot.esp32s3: SPI Mode : DIO**
I (40) boot.esp32s3: SPI Flash Size : 16MB
Looking at the SPI Flash mode its in DIO, not QIO - then I noticed in my platformio.ini I have an arduino setting
board_build.arduino.memory_type = qio_opi
How do I change the platformio to specify the memory type as QIO for espidf ?
Ok I now see that with this approach some settings will be in the platformio.ini, but other settings on the espidf side will be in the sdkconfig file in the project folder i.e. sdkconfig.esp32-s3-devkitc-1
Q1 - When I do a clean and build is the file sdkconfig.esp32-s3-devkitc-1 copied to the sdkconfig and then the platformio settings are written in the sdkconfig aswell ?
Q2 How do I edit things sop they dont get overwritten or cleaned ? Do I edit the sdkconfig file, or the sdkconfig.esp32-s3-devkitc-1
Also - how do I set the program to load into core 1 ? As I can see its on core 0, which for the Arduino version set the executable to core 1, so I presume I need to do the same here with the espidf framwork ?
This is the error I see from UART now

I can see core 0 is where the panic is, and I presume I need to setup memory somehow, or switch execution to core 1 ?
