Thanks for your suggestion. However, this is not my case. I tried to unplug any jumpers or connection and just monitor (make monitor) and the Wrover KIT reboot when it call gpio_matrix_out() to set MOSI pin. It looks like a segfault in ROM code then reboot is triggered.

Dear ESP32 team,
I also new to ESP32. I bought 2 Wrover KIT and I faced the issue with IO13.
My application will configure the VSPI pin as following:
#define SPI_HOST VSPI_HOST
#define GPIO_MOSI 13 //13 //19 //VSPIQ
#define GPIO_MISO 12 //23 //VSPID
#define GPIO_SCLK 14 //18 //VSPICLK
#define GPIO ...
