ESP32 - PRO CPU has been reset by WDT

I have repeating resets of ESP32 controller with these warning messages:
Dev board based on ESP32.

First of all why checking out an old specific commit? you should try the latest master.
Secondly, How many freeRTOS tasks are there in your project or are you trying this example as it is? is it ESP32 or ESP32-S2, C3, S3 ??

First:
I have checked out to latest commit and getting Errors and resets too:

W (196) boot.esp32: PRO CPU has been reset by WDT.
W (202) boot.esp32: WDT reset info: PRO CPU PC=0x400841e6
0x400841e6: _xt_panic at C:/Users/esp-idf/components/esp_system/port/arch/xtensa/panic_handler_asm.S:29
W (208) boot.esp32: WDT reset info: APP CPU PC=0x400858d2
0x400858d2: panic_handler at C:/Users/esp-idf/components/esp_system/port/panic_handler.c:148 (discriminator 1)

Second:
I don't have any freeRTOS tasks.
Dev board based on ESP32.
ESP-IDF: v4.3.1

Since you are using ESP32 (I have tested in ESP32-S2) you will have to map the GPIO pins which support only GPIO output. and also do gpio_pad_select_gpio for required pins.

Comment HUB75E_Init(); in app_main and add a print inside while() and see if it's running. If it is running then you have to fix the IO init for ESP32

while (1) {
HUB75E_displayBufferPixels();
vTaskDelay(10 / portTICK_PERIOD_MS);
}

try like this is ok
