ESP32-C5
Device Description
WT0132C5-S6 series module built-in ESP32-C5 N8R4 series chip with UART module and two additional buttons for chip configuration.
Hardware Configuration
CH340 USB-UART converter, GPIO 27 is connected to Download Boot Button, 28 - SPI_boot button
Version
v3.3.0
IDE Name
VSCode Platformio with pioarduino, Arduino IDE
Operating System
Windows 11
Flash frequency
80 MHz
PSRAM enabled
no
Upload speed
115200
Description
The ESP32C5 constantly resets because of watchdog timer (rst:0x8 (TG1_WDT_HPSYS)) when running even the most basic Arduino sketch.
Reset Pattern:
System flashes and boots normally;
Code executes briefly (prints all outputs in setup and loop);
Timer Group 1 watchdog reset occurs (rst:0x8 (TG1_WDT_HPSYS));
System reboots and repeats the cycle.
Looks like new release can't handle interrupts properly, hence IWDT issue.
Sketch
#include <Arduino.h>
void setup() {
Serial.begin(115200);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB
}
Serial.println("Hello, World from ESP32!");
}
void loop() {
Serial.println("Still alive...");
delay(1000);

Other Steps to Reproduce
On Arduiono IDE I use the latest release, and on platformio my .ini is:
[env:esp32c5]
platform = espressif32
board = esp32-c5-devkitc-1
framework = arduino
monitor_speed = 115200
