I am an amateur in C and an expert in electronic design since more then 30 years.<br/>
I am working on a personal project on a MINI D1 ESP32 based on the module AZ-delivery EPS32-WROOM-32.<br/>
The goal of this project is to convert 18 channels Spectrum audio analyser.<br/>
Actually, the code is converting the right and left channels into 2048 FFT signals and crates the 18 channels to displays. These data have to be send to another MCU through a SPI single data.<br/>
When the code try to send the first data, the MCU goes into panic mode and reboot. See below :

<e>The code is written under Vscode with :
* Espressif IDF v1.6.5

I Would like to know how to solve the issue.
Is Someone can help me in this task ?
