To fix the issue, you will need to find out the precise module you are using and set **PSRAM** in the Arduino IDE Tools according to the following table.
192+
193+
How to determine the module version:
194+
------------------------------------
195+
196+
* First determine if you have a `WROOM-1 <https://www.espressif.com/sites/default/files/documentation/esp32-s3-wroom-1_wroom-1u_datasheet_en.pdf>`_ or `WROOM-2 <https://www.espressif.com/sites/default/files/documentation/esp32-s3-wroom-2_datasheet_en.pdf>`_ module - this is written on the module shielding almost at the top, right under the ESP logo and company name (Espresif) right after the ESP32-S3 - for example ESP32-S3-WROOM-2.
197+
* Then locate the version code on left bottom corner on the module shielding. The markings are very small and it might be really difficult to read with naked eyes - try using a camera with careful lighting.
198+
199+
With this knowledge find your module in the table and note what is written in the **PSRAM** column.
200+
201+
- If the results is empty (-) you don't need to change anything
202+
- For QSPI go to Tools > PSRAM > QSPI PSRAM
203+
- For OPI go to Tools > PSRAM > OPI PSRAM
204+
205+
Note that WROOM-2 has always OPI.

3535
* Some of the GPIOs are **INPUT** only.
3636
* Some peripherals have output signals and must be used on GPIO's capable to be configured as **OUTPUT**.
3737
* Some peripherals, mostly the high speed ones, ADC, DAC, Touch, and JTAG use dedicated GPIOs pins.
38+
* Some pins are used to connect flash memory on the module - this prevents them from any other use - if a peripheral is routed to one of these pins the device will not be able to boot.

Before assigning the peripheral pins in your design, double check if the pins you're using are appropriate.

This partition will use about 12MB of the 16MB flash. The offset will be automatically calculated after the first application partition and the units are in K and M.

A alternative is to create the new partition table as a new file in the `tools/partitions <https://github.com/espressif/arduino-esp32/tree/master/tools/partitions>`_ folder and edit the `boards.txt <https://github.com/espressif/arduino-esp32/tree/master/boards.txt>`_ file to add your custom partition table.

Another alternative is to create the new partition table as a new file, and place it in the `variants <https://github.com/espressif/arduino-esp32/tree/master/variants>`_ folder under your boards folder, and edit the `boards.txt <https://github.com/espressif/arduino-esp32/tree/master/boards.txt>`_ file to add your custom partition table, noting that in order for the compiler to find your custom partition table file you must use the '.build.custom_partitions=' option in the boards.txt file, rather than the standard '.build.partitions=' option. The '.build.variant=' option has the name of the folder holding your custom partition table in the variants folder.
