Programming Code Loading on ESP32-S3 WROOM2, but not executing

Other Hardware 3rd Party Boards

Hi there,

I would appreciate if someone would like to assist me.

I am using ARDUINO IDE 2.0.3 for loading a code for testing the execution on ESP32S3 WROOM-2 of the programming code of a blinking led ON and Off, but it seems is not working.

It successfully loads on the ESP32S3, but when checking the Serial Monitor i get the following message:
ELF file SHA256: 8152604156c60b52

E (185) esp_core_dump_flash: Core dump flash config is corrupted! CRC=0x7bd5c66f instead of 0x0

Rebooting...

Many thanks.

I'm not familiar with the ESP32S3 so probably can't help. But I think it will help others to help you if you post your code.

Core dumps happen when your code accesses memory that it's not supposed to access (e.g. writing outside boundaries of an array).

what particular ESP32-S3 board are you using?
what pin are you attempting to blink? are you sure it is connected to an LED?
on a ESP32-S3-DevKitC-1 the File>Examples>Basics>Blink works OK using LED_BUILTIN

i have resolved the issue, by changing to the following:

Tools
FLASH MODE ---> OPI 80 MHZ
PSRAM ---> OPI PSRAM

Now the code uploads, compiles and processes the execution well.
